Magnet environment in Riyadh Military Hospital ICU unit Essay

Magnet environment in Riyadh Military Hospital ICU unit - Essay Example Many of the United States hospitals have engaged in developing plans required for reorganizing the nurse staffing while reducing operational cost to fit the magnetic environment according to Halligan (2006). These hospitals are using the magnetic approach in restructuring the nursing system that has proofed to be advantageous as it makes use of external management consultants who serve similar role with nurses hence reducing nurse retention. Since the introduction and implementation of magnetic hospitalization in Riyadh military, the hospital has experienced significant changes in its health care method of operation. Most of the implementation of magnetic environment focuses on the nurse job satisfaction as well as their turnover. Riyadh has to device a way o f retaining its magnetism in order to improve its nursing staff condition by examining cost containment and reorganization. The management in Riyadh has however shown that the hospital has been reluctant in revealing its reorgan ization process to the consultants for guidance according to Cranley, Cummings, Ferrone, Harvey and Tourangeau (2010). This is because they believe they best positioned to identify their appropriate change direction. The aspect of magnetic environment implementation in Riyadh should be because the nursing staff has been experiencing significant restructuring as well as external configuration. The general mix in nursing skills and sponsoring therein in service education is definitely an aspect that needs to be incorporated in implementation of magnetic environment. This is because such training reduces nurse attrition as well as rationalizing nurse retention as suggested by Magnet (2005). Due to the current shortage of nurses in the country, Riyadh Military Hospital intensive care... The main topic of the essay is the implementation of magnetic environment in Riyadh Military Hospital ICU unit involves clinical specialists’ deployment, more flexible working schedules, and professional models of care delivery. This essay then tells more about the evolution of nursing as a profession that has led to many hospitals to pursue magnetic accreditations hence a resurgence in the nursing grant rounds. The essay then goes through a specific case of intensive care unit in Riyadh Military Hospital, which is a challenging environment. As a result, there needs, a well-implemented magnetic environment to ensure there is nurse attrition and retention. This is because the intensive care unit deals with critically ill patients. This needs to take place in a magnetic environment where nursing, respiratory, and medical teams need to expect problems and stay informed of the patient’s problem. For the past four years, Riyadh Military Hospital has experienced a rapid impro vement in patient outcomes and this is attributed to the well-implemented magnetic environment. This has been due to the reduction in nurse attrition for those nurses who contribute to their best towards the critically ill patients. The aspect of magnetic environment implementation in Riyadh should be because the nursing staff has been experiencing significant restructuring as well as external configuration. . The implementation department should put into consideration that in promoting the retention of the nursing staff they should focus on modifying the work place.

Different approaches to corporate governance

Different approaches to corporate governance Corporate governance is almost frequently viewed as both the construction as well as the rapports which ascertain collective direction as well as functioning. The board of directors are generally fundamental to corporate governance. Its rapport to the former basic players, generally stockholders as well as management, are vital. Other participants admit workforce, consumers, providers, as well as creditors. The corporate governance model besides depends upon the legitimate, regulative, institutional as well as honourable surroundings of the profession. (Dignam, A, 2006) CORPORATE GOVERNANCE The full term Corporate Governance isnt easily to specify. The condition governance concerns for a procedure of deciding as well as applying the determinations in the concern of every stakeholders. It essentially associates to growth of corporate functioning as well as ascertains right accountability to direction in the concern of every stakeholder. The Cadbury describe of 1991 on Corporate Governance conceives it as the strategy by which corporates are guided on as well as organized. Corporate governance is the strategy through which organizations are addressed as well as handled. It determines how the aims of the organization are fit as well as accomplished, however danger are supervised as well as evaluated, and how functioning are optimized. (Cadbury, 1991) DIFFERENT APPROACHES TO CORPORATE GOVERNANCE JAPAN Abiding by the 1945 frustration, Japanese zaibatu or organization groupings were broken down, firm has intimately determined by governance. The requirement for japan to regain subsequently the warfare headed to end governance management of firm, by a centre on development in exportations as well as marketplace apportion besides profitableness. Organization boards dont commonly assemble often as well as the organization is generally handled by the chairman as well as his functioning commission, wherever actual authority is practiced along with determinations taken which is entirely hand stamps by a control board. FRANCE A lot of great businesses in French Republic have till lately been operated by governance. A few individual organizations for instance: Renault, Michelin who have an eminent external visibility, but almost of these have trusted on a hard basis of French marketplace abide in decree to go international. Almost French organizations are comprised as well as are handled by general manager who are responsible for stockholders. Greater as well as cited organizations are integrated. GERMANY German corporate governing is rooted in the OECD rules of May 1999, which constituted written for cited organizations in Jan 2000 through the German board on corporate governance. (Adrian Davies, Chapter 2) DIFFERENT TYPES AND COMPARISONS OF CORPORATE GOVERNANCE Board of Directors A board of directors are a corporate governing mechanism which protects the concerns of a organizations stockholders. The board is much responsible in brushing up organization direction as well as taking out persons who do not amend the organizations general fiscal operation. Audits Audits are an autonomous critique of an organizations patronage as well as fiscal functioning. This collective governance ascertains which enterprises or companies adopt domestic accounting principle, rules or different extrinsic guidelines. Audits could besides amend a companys abiding in the organization surroundings. Additional organizations perhaps more amenable to act upon by an organization that is a firm record of functioning. Balance of Power Reconciliation authority in a company ascertains that no individualist has a power to overstrain resourcefulness. Dividing obligations among board members, directors, managers and other persons ascertains that all separate obligations have well reasonably to the company. Making distinct characters besides continue the business adaptable, ascertaining that functional alterations or novel employs could be built without disrupting present functioning. (Adrian Davies) LEADERSHIP Leadership is a procedure for bringing matters executed by folks. The quarterback acts the squad toward a touchdown. The elderly patrol leader directs the group for an eminent evaluation at a camporee. These leaders are bringing work acted through acting by folks. Theyve employed the procedure for leaders to accomplish definite destinations. Leadership isnt a scientific discipline. Therefore representing a leader is a hazard as one could never make certain whether one would accomplish the objective at the least in present time. (Scoutmasters, BSA, 1937) ORGANIZATIONAL CONTEXT LEADERSHIP Commonly on superior betterment efforts top-ranking leadership establishes transformational conducts that were accompanying winner for those enterprises. Public constitution could be demographic variance among the company or capacities for persons as well as groupings. In leadership literature a few accent inclines to sexuality, as well as employees heterogeneity along with its effect on leaders or execution. No stress inclines to the transformational leaders. Operations admit the manner of governing, Human Resource Management strategies and so forth however procedures themselves are not generally the basic centre for the empiric explore. Almost of the reports in the leadership literature discoursed the consequences of province or stipulate as the contextual inconsistent entirely at the greatest stages of companies as well as hold centred on mass alterations along with crises affecting top management squads, chief executive officer along with Boards of Directors. (Lyman W. Porter, Grace B. McLaughlin; 2006) LEADERSHIP APPROACHES Traits approach Leadership trait hypothesis is the thought that individuals are birthed by convinced quality traits or calibres. As convinced traits are assorted by skilled leaders, it adopts that if one can discover individual by the right traits, one would be capable to discover leadership as well as individual by leadership prospective. Group approach In counterpoint to human leadership, a few companies have taken in troop leadership. In that position, much one-man caters management to a squad in general. A few companies have admitted the approach in desires of growing creativeness, cutting prices, or retrenchment. Behavioural approach Behavioural leadership isnt actually a character of leadership. Alternatively, its analyse for the forms of activities as well as behaviours which comprise what the company could address the leadership mode. LEADERSHIP STYLES o Authoritarian or autocratic The mode is utilized whilst leaders narrate their workforce what they require to do as well as how they need them achieved, without bringing the advice for their followers. o Participative or democratic The mode implies the leader admitting one or several workforce in the deciding procedure o Delegate or Free Reign Therein mode, the leader admits the workforce to build the determinations. (Hofstede, Geert, 1977) Situational approach Additional approach to leadership analyses is the situational approach, the primary preface of that is dissimilar positions require dissimilar cases of leadership. A position, among the circumstance, is an determined of measures as well as positions among which the people or troop has to consider in a procedure of activeness as well as with reference to which the action is designed as well as its consequences apprized. Transformational approach Transformational leadership is specified as the leadership approach which efforts alter in people as well as social structure. In its perfect anatomy, it produces worthful as well as favourable alteration in the followers by the last objective for growing followers into leaders. Inspirational approach The power to urge individuals to accomplish large altitudes of execution as well as winner is an attainment that leadership require. Passion, intention, hearing as well as significance assist attain a leader inspirational. (Kendra Cherry) CHANGE MANAGEMENT Change management is an integrated approach path for changing or transitioning people, squads, as well as companies as of a present province to a desirable prospective province. Its an organisational procedure aspired at authorizing workforce to consent as well as adopt alterations in their present organization surroundings. (Hiatt, Jeff, 2010) FACTORS TRIGGERING CHANGE IN AN ORGANIZATION All business carries out points of shift which could drive strain along with uncertainness. To be productive, companies have to adopt a lot of characters of alteration. The extrinsic surroundings are impacted by governmental, societal, and technical, along with economical stimulations exterior of the company which drive alterations. The interior surroundings are impacted by the companys management strategies as well as modes, systems of rules, as well as processes, and workforce postures. (Cliffnotes) APPROACHES TO CHANGE MANAGEMENT Kurt Lewins approach The framework is constituted in a common schemes possibility, a lot of specifically, its referred by the drives that hold down equal schemes or those which breach it down. Socio technical approach It distinguished quasi- independent work on troop as the initiation of some company as well as besides it has greater suitable to the requirements of organization it was little thoughtful to the basic requires of the workforce such as job gratification. Lean production approach Its supported the precepts for zero faults; zero stocks as well as zero languish, by the consolidation of every system of rules. Total Quality Management approach Its accompanying lean output. Alike lean output, TQM employs to the all functional strategy by full incorporated work squads as well as centres on calibre as well as consumer demands. (Stroh, U M, 2005) BRITISH AIRWAYS In the year 1981, British Airways brought out panel afresh chairman. Whilst the chairman commenced, he observed that the organization was really ineffective as well as was ravaging a lot worthful resources. To build the company more advantageous, this chairman determined to reconstitute the whole business. He accomplished that the greatest method to do was by change methodological analysis management program. Consistently, the company set out contracting their employees. However, earlier they acted this, by his change direction leadership, the chairperson devoted the organization the causes for the reconstituting as well as privatisation of the organization in decree to develop them for the forthcoming alteration. Therefore, by leadership as well as communicating, he guided his organization by a hard time which can had unfortunate without competent change management opposition communicating. (Mistyfaucheux, 2009) CONCLUSION Effective corporate governance structures promote organizations to produce esteem along with put up accountability as well as command systems of rules in proportion to on the dangers involved with. Effective corporate governance structures promote organizations to produce esteem along with put up accountability as well as command systems of rules in proportion to on the dangers involved with.

A Descriptive Analysis of Nigger: The Meaning of a Word by Gloria Naylo

A Descriptive Analysis of Nigger: The Meaning of a Word by Gloria Naylor What is the rhetor’s purpose? In the essay â€Å"Nigger: the meaning of a word† Gloria Naylor discusses the essence of a word and how it can mean different things to different people in a myriad of situations. Depending on race, gender, societal status and age Naylor outlines how a word like ‘nigger’ can have different meanings within one’s own environment. Naylor discusses how a word can go from having a positive to a negative connotation merely due to how it is spoken and by whom. Naylor shares a personal experience with her audience as she describes the first time she really â€Å"heard† the word ‘nigger’. A young white boy in her third grade class spit it in her face. Naylor states, â€Å"I didn’t know what a nigger was, but I knew that whatever it meant, it was something he shouldn’t have called me.† (Naylor 460) Naylor writes about her own personal experience and is obviously biased. This, while powerful, can also be seen as a limited view of the subject. Her audience only understands thorough her eyes and her experiences. Naylor is trying to educate her audience by sharing a personal experience. I think she wants her audience to sit back and think about the words they use and how others may use them and how this can affect others. Naylor wants her audience to understand how she was affected not only by a young boy but also by how she didn’t really think about the word ‘nigger’ until the moment it was used to hurt her. She is striving to make her audience think about the words they use and hear and how the context these words are immersed in can change the meaning of them. Who composes the target audiences? To be a part of Naylor’s target audience one must have obviously had experience with language and how people use it. She is targeting those who have heard and/or used the word â€Å"nigger† before. Naylor wants her audience to take on her experience and be empathetic towards her. She doesn’t do this in a seemingly pathetic way, as she seeks no pity. She outlines her experience and wants her audience to understand her view and how this view came to be. What roles or personas does the rhetor assume? Naylor assumes the role of an educator in her writing. She assumes a persona of a young girl experiencing a new way of understanding a word. ... ... She uses a conversational tone that adapts nicely to the audience. I say this because draws the reader in and he or she easily understands and accepts her experience. Naylor uses her experience to exemplify her point and to offer validity. One is drawn in by her experience as a young girl, and her evolution of understanding. Naylor makes her audience think about what it would be like to really â€Å"hear† a word for the first time, to look back and realize you had heard the word many times in a different context. What strategies are used? The language used by Naylor is common, as she doesn’t use large words one has to look up to understand. She writes in low style which is effective for her argument. This use of languages conjures an almost friendly relationship with her audience, like she is sitting down with you over a cup of coffee discussing how context can change your understanding of a word. She is sharing a part of her life and experience with the audience in order to shed light on her argument. Works Cited: Naylor, Gloria. â€Å"Nigger: The Meaning of a Word† Ed. Goshgarian, Gary.

Blood Bank

Blood bank Although there are any complicated instruments in the blood bank department, but it’s a very important and sensitive section of the medical laboratory as it deals with donors and acceptors of the blood, it transfer for leukemia and thalasemia patients, new born and cancer patients and so many cases blood bank save their lives. Tests that are carried in this department: 1- Some tests, which included donated free of diseases, serology tests 2- blood grouping 3- rhesus factor†Rh† 4- direct & indirect coombs test 5- cross matching 1-serology testsTo ensure that donated free of infectious diseases as HIV, Hbs, VDRL These tests are rabid tests using a card [pic] 2- blood grouping Red blood cells contain on their surface on Ag A,B, and the have their antibodies in the serum on the same red blood cells. That means, that every blood group can give a specific other group and receive also from a specific one in order to avoid agglutination and so blood clotting. [p ic] Method 1: On a slide put two drops of blood- -Add a drop of anti A on the first blood drop, and a drop af anti B on the second blood drop – mix and wait for 2 minutes – observe the agglutination if happened with anti A the blood group is A [pic] You can use a test tube instead of the slide, and then put the tubes in the centrifuge and watch the agglutination found 3- Rhesus factor â€Å"Rh† Is a complex antigen â€Å"D† found on the red blood cells and has its anti in the serum of the blood. 85 % are Rh + which has D in their blood Its very dangerous if persons, which are Rh negative received Rh positive it makes agglutinations, and may lead to death. Method : -As in the blood grouping -Put a drop of blood + a drop of anti D Mix together, observe the agglutination – -If found any agglutinations, its Rh positive. -direct & indirect coombs test This test is carried out to detect the presence of incomplete antibodies, which would react with double of complete antigen making a clot. And these are very serious and dangerous cases. A- direct coombs test Detect antibodies reactive with RBCs and conjoined Bhaotkon these objects is incomplete and not have the ability to cause coagulation alone and shows Taktherha only after the addition of serum Coombs. This test is very important in diagnosis many cases, the most popular is â€Å"Hemolytic anemia of new born†, lead poisoning, some drugs, inherited hemolytic anemia.Method: -Add drops of blood in a test tube and wash using saline 2-3 times( â€Å"wash† as the word means, add saline to the blood and through the filtrate 2-3 times making a bloody suspension) – add 2 drops to the washed Rbcs, and put the tube in the centifuge – examine the formation of any agglutination first with nacked eyes then using microscope. – if found it’s a positive coombs test B- indirect coombs test: to detect the presence of free antigens in the blood, not attached to red blood cells. Method: – prepare a sample of blood group O+ and wash with saline 2-3 times 2- put drops of patient serum in a test tube, add 2 drops of washed O+ blood 3- put in a water bath for 40-60 minutes 4- after 50 minutes add â€Å"bovine serum albumin† to the tube 5- wash again with saline 3-4 times 6- add 2 drops of coombs anti human globuline, and then put into centrifuge 7- observe the presence of agglutination 8- if found before add coombs reagent = presence of anti D 9- If found after add coombs reagent= presence of incomplete anti D 10- If not found at all= negative test. [pic] -cross matching The cross matching test is very important in case of blood transfusion from donors to acceptors as the blood group and Rh should be identical to each other. So sample of blood of donor and acceptor is added to each other and checking for any formation of clotting, if found that indicates that they are not suitable for each other At first the blood group and th e Rh type is detected before carring out the cross matching, and they should be identical Simply add drop of donor blood + drop of acceptor blood and mix well and watch for agglutinations formedIf any agglutination formed that’s means the donor and acceptor blood are not identical The figure below explain the procedure briefly. [pic] Blood bags colors: For keeping blood bags colors are as follows: Red is the color of blood is used to save the type (o) Yellow color is used to save the blood of type (a) Green color is used to save the blood of type (b) Blue color is used to save the blood of the type (ab) This poster, which shows color should clarify the patient's name and for keeping the blood bag and the type of preservative and temperature required to save the blood and the name of the hospital blood and date of preparation.Anticoagulants used in blood bags: Is non-clotting materials added to the blood bags Blood Bag These materials vary its chemical content, which in turn a ffect the period of keeping the blood. 1 – Material CPD: It knows its components citrate phosphate dextrose and that preserve blood for 21 days after mixing blood, under colder than 2-6 degrees Celsius. 2 – Article CPDA: They are the materials the previous addition of adenine, which in turn kept the blood for 29 days in the same previous methods. 3 – Article CPDA-I: This article reservation blood for 35 days ,save the whole blood.These three materials used amount of 63 cm ? full unit of blood is added about 400-450 cm ? of whole blood by withdrawing blood from the donor. Where that blood saves temperatures of 2-6 degrees Celsius private refrigerators to save the blood. 4 – SAG-M material or substance ADSOL: used to save the concentrated red blood cells for a period of 42 days degrees cooler than 2-6 degrees Celsius. This method using a 100 cm ? the sag-m or ADSOL be present unit separate from the whole blood units and connected pipe tight and sterile.As t he blood drawn from the donor and mixes textured CPD usual and after by the apartheid regime through centrifugal force refrigerated centrifugation separates blood plasma to the unit empty neighboring unit blood then keep red blood cells concentrated alone which are added directly 100 cm ? of the foregoing adsol / sag-m to keep red blood cells to centralize for a period of 42 days. 5 – Article Djileerool glycerol: Reservation concentrated red blood cells for a period of 15 years or more and under cooler from 65 to 200 degrees Celsius below zero.This modern way used to freeze red blood cells concentrated from rare species or negative and is dissolving blood frozen after that when usage and the need for washing cells red, textured saline-glucose solution to remove material Djileerool of blood and then later used these red blood cells to patients. The means of blood plasma and sludge near, it is frozen in freezers less degree cold out to about 30 to 35 degrees below zero and one year AD full, but platelets, they kept for five days in a continuous motion to prevent damage, and the degree of conservation of 20-22 degrees Celsius.Types of Blood Transfusion Blood Transfusion: Full blood transfusion whole blood: The simplest kinds of transport where blood is taken from the donor and kept in the fridge at a temperature close to almost 8 degrees. Which is used during times of emergency, But loses its anti-bleeding elements. Transfer plasma: As we know consists of blood â€Å"red blood cells + plasma† If red blood cells transport oxygen. The tasks of the plasma containing elements prevent blood clots. And thus will be useful for many patients and gives better results and faster as patients liver.As well as a pint of pure plasma is easier on the body of a mixed-liter of whole blood. Transfer platelets: It is relatively more expensive and needs modern major hospitals. Or be separated manually through lab technician but needs a sterile room at 100%, which may b e difficult to get it continuously. The mean platelet extract â€Å"only† from the donor and returned the rest of the blood â€Å"plasma + erythrocytes† donated to the same moment. It is suitable for patients who suffer from a shortage of blood platelets, which help heal wounds. Refrigerators Blood Bank: You will find two types of refrigerators: – refrigerators for keeping blood bags full whole blood: And often have gate transparent glass shelves. Each rack of a particular department or certain species. There is, for example, a special rack Balveselh A-or there is a special rack, Department of Orthopedic.. Each section has a share of the blood bags. There is a special rack emergency. Wharf special surplus â€Å"given any section†. Refrigerator temperature appears on a small digital screen. In addition, the average temperature of 8 degrees Celsius. 2 – refrigerators to save plasma bags: temperature of about 43 below zero ..Because plasma contain ele ments prevent icing and prevent bleeding and proteins need to lower temperatures to save Blood transfusion bags: Per bag hose blogger called â€Å"tube†, Recorded in the book Blood Bank. As an example: No. This bag is hose 123456a .. And on each paper bag writable. Adzun â€Å"name of the donor† and â€Å"the name of the patient† and â€Å"taking blood† and â€Å"blood†. Daily and periodically examine the contents of refrigerators of blood bags and review its date. In the event of termination validity blood bag is left out of order execution .. Blood bags execution: Be executed â€Å"get rid† of blood in two cases.Either analyzes showed that the donor patient in one of the viruses â€Å"hepatitis or AIDS or syphalis† Or â€Å"expiration blood†. Collect the bags to be culled in environmental bags â€Å"red†. And closes tightly car to take them medical waste to get rid of them safely through the burning in special containe rs .. Books of blood transfusion: All data is recorded books, Name of the donor, blood type and result of the analysis and the compatibility and tube. When asked for any blood bag section. The technician or doctor reviewed the book and the contents of the fridge and writes a receipt or revenue blood bag, such as banks completely

A comparative analysis of traditional software engineering and agile software development Essay

Various industries handled information and data manually until 1960 when the first software development methodology was hinted. Software development methodologies are key steps in development of information system. Different methodologies have different requirements in terms of cost, time frame, expert requirement, size of the business, maintenance cost, and flexibility in case of changes in the future among others. Therefore, organizations evaluate each methodology in order to come up with the most effect one for their information system development. Software methodology involves a structural framework to plan and manage the processes that are involved in development of information system.Prototyping and dynamic system methodology will be critically evaluated to understand the role of software methodologies in information system development. Dynamic system development methodology                The method ensures frequent delivery of information system in businesses. The methodology is can be reversed during development in case of errors, and the requirement is based on high level and integrated testing throughout lifecycle, which allows collaboration and cooperation between all stakeholders (Association of Modern Technologies, 2014 Software Development Methodologies) Critical evaluation                Since this methodology involves end users and teamwork decision, it forms the best choice for information system development. Future changes can be accommodated since changes are reversible. This methodology follows PRINCE concept since it start with initiation of a project and conclude with crossing of the project. Prototype methodology                In this methodology, incomplete software is created, which differs with the final product (software development and engineering, 2012 n.p.). The methodology makes it possible to evaluate the software during the development process and design before it gets to the final step. The software can also be tried before integration in an organization. This method allows involvement of the users and evaluation during designing phase and thus increasing the likely hood of easier implementation in any organization. Critical evaluation                In this methodology, users, builder and system interaction are mandatory. It requires expertise for both builders and end-users. With this model, time and cost are decreased compared to traditional method, which becomes a major consideration when developing information system. This methodology is applied mostly in situations there is risk uncertainty. This methodology is best applied in managerial systems, as its main objective is planning, direction, controlling and decision-making. This forms one of the choices for information system since users can be able to do a value analysis and investment can be made at relative increments. PRINCE plays an important role in information system development since it establishes the management, control, and application of the appropriate software for information system. It gives more insight about the software developed and provides authenticity of the software, which is important in making information system decisions. Question 2 According to (Bantra et al, (2010 p 383) agile methodology is based on various values such as Individual and interaction over processes and tools, Working software under comprehensive documentation, Customer or end user collaboration over a contract negotiation the and Responding to changes over following a plan                The agile methodology builds flexible information systems that can be upgraded or changes in future (Rao, Naidu, & Chakka, 2011 p. 42). For example, if an organization wants to expand its system, it can build its new information system on the existing system. Hence, the methodology is adopted where future changes in the information system are expected. Time aspect makes this approach cost effective. The methodology involves the end users at every stage making software development process effective and accurate (Aitken & Ilango 2013 4758). In addition, the process is fast and efficient thus ensuring that the information system development easy and economical. The traditional methodologies are fixed and do not allow future changes (Aitken & Ilango 2013 p. 4756). That means that once the information system is developed using the traditional methodology, it will be hard to build a new system using it. The expansions or future changes in the information system require engineers and software developers to start a new system. This is not cost effective for business since they are always in a constant growth and keep on improving their information systems. Thus, agile methodology best suits development of a flexible information system that can be upgraded easily. Question 3                The Structured systems analysis and design method, (SSADM) is one of the widely used methodologies in computer applications in private and public sectors since its inception in 1981. The methodology operates under three principle techniques known as logical data, flow data, and event modelling (Al-Humaidan, & Rossiter, 2011, p 3). Logical data modelling (LDM) technique involves identification and documentation of the necessary data for business or organization information system. The information that the business wants to record on the information systems is identified and documented for inclusion in software development. Consequently, the data flow modelling (DFM) techniques involves identification, modelling and documentation of how the identified data using LDM technique will flow in the information system. It gives details on how various data will be transformed in the system. Then, event modelling (EM) technique identifies and documents the sequence of events in DFM. The techniques help the engineers to develop information system that meets the end users need since it allows participation of all the stakeholders. However, inadequate research may result to development of poor information systems, which may be cost to the business. The SSADM uses various tools that are important in development of information system. Data flow diagram, (DFD) highlights all the data pathways, while other tools such as data dictionary, decision trees and tables give guidelines on data classifications. The tools make operation of the information easier for the end users. Unified modelling language, (UML) is a language used in software engineering. It helps the developers to create a system using a standardized language that can be understood easily by both the participants and the system. The main techniques and tools used are diagram and language structures such as class, interactions and activity diagrams (Al-Humaidan, & Rossiter, 2011, p 4). The main difference between SSADM and UML is that the former interfaces are composed of design dialogue while the latter utilises components and classes of modelled diagrams as interface (Al-Humaidan, & Rossiter, 2011 p. 24-29). In addition, SSADM uses requirement catalogue as the data resources while UML uses modelled stereotype features as data sources. Question 4                Software development approach entails identification the information system issues and making decision of how the issues should be solved and the solution remains viable. Critical evaluation                The approach helps to develop software in a top down development consisting of independent steps that are completed sequentially. The engineers are able to evaluate each step independent and develop consecutive phases based on completed ones. The methodology is fast and effective for development of small information systems. However, methodology is not suitable to develop large information system because it is slow and cumbersome. In addition, the approach is costly and a short term. According to Stoica et al, (2013, p. 68) this method requires product definition, clear understanding of requirements and technology, and expertise and the system is short lived. End users approach                In this approach, the end user is the developer of the software. He or she designs the software such that it is able to meet his or her needs. This is done through modification of commercial off-shelf software (COTs). Critical evaluation                The approach does not involve formal designing of the information system. The approach does not require documentation of the project. The end user is the main controller of the information system developed from this approach. However, it is not fit for large business and lack of documentation limits future changes of the information system would be very hard. Thus, the approach is not economical especially of growing enterprises. When the size of the project is large, the software development approach is based on the cost or budget limitations, timeframe taken by the approach, and the flexibility of the approach. This is because, the organizations designs information systems that are economical in that they does not affect their profitability and operations. Approaches that are cheap and are executed in a short span of time are preferred to others that are costly and take long time before completion References Aitken, A., & Ilango, V. 2013.
