It also wants to better manage its membership data and offer its members enhanced e-commerce and communication capabilities for booking any sport court such as badminton, table tennis, swimming lesson etc. As a systems analyst working within a software development organisation, you have been given the task of producing a PROPOSAL for the development of a new system, to meet the following requirements; • New Membership management and subscription renewal • Taking new, overdue and reward payments • Sports court and swimming session booking • Product marketing and online ordering The system development must focus on cost efficiency but importantly must fully meet the above requirements in a short development time scale. YOUR PROPOSAL MUST ADDRESS THE FOLLOWING TASKS. EACH TASK SHOULD BE COMPLETED IN THE WORKBOOK. Assignment title Systems Analysis Purpose of this assignment In this unit learners are provided with a detailed insight into the systems analysis life cycle. They are also taught Modelling tools and techniques, testing procedures and the need for systems evaluation. This unit we examine the requirements of analysis for both commercial and technical applications. It will also introduce the data and functional modelling techniques, which the learners can be expected to use. Task 1 (AC: 1.1, 1.2 and 1.3) i. Identify the functions and purpose of each stage of a systems development life cycle (SDLC) ii. Compare the most widely used life cycle models and their corresponding development methodologies iii. For the given case study briefly state with reasons a suitable systems development life cycle and a development methodology. Task 2 (AC: 2.1, 2.3, 3.1, 3.2 and M1) i. Analyse and discuss the importance of accurately capturing the functional requirements of a software system. ii. Outline the strategies you would propose for the above case study. Task 3 (AC: 2.2, 4.1, 4.2, 4.3 and M2) i. Design a solution for the specified case study requirement using; a. An object oriented analysis and design methodology b. A traditional methodology based upon data flow and entity relationships Ensure that for both (a) and (b) methodologies you include appropriate diagrams to show the OUTLINE of your design Task 4 (AC: 3.3 and D1, D2) Analyse and Evaluate the system design that you have developed. Comment on the effectiveness of your design diagrams, compare strengths and weaknesses of the two development methodology approaches, traditional and object oriented. This task requires students to undertake more private research, reflect on their own learning and demonstrate a comprehensive knowledge of the concepts of system analysis, in order to be awarded a Merit or Distinction. TASK 1 The FOUR key stages of a systems development life cycle (SDLC) are shown below; The Function & Purpose of Stage 1 is; Create software requirements specifications the basis for an agreement between clients and contractors or suppliers The Function & Purpose of Stage 2 is; Originally released as a methodology is a systems approach to the analysis and design of information systems. Central system produced and also communicate The Function & Purpose of Stage 3 is; Structured Systems Analysis as well as Design is a way used to overview and analysis of information systems The Function & Purpose of Stage 4 is; With input from the system design, and development of a system for the first time in a small programs known by unit , which is integrated in the next phase each unit functions of development and testing , and which is referred to as the unit test THREE of the most widely used Life Cycles + Development Methodologies Life Cycle: Waterfall-model Advantages; This model is simple and easy to understand and use plus is easy to manage because of the hardness of the model each stage has specific outputs and for the review process. In this model it is processed stages and finished at one time. Disadvantages; Once the application is in the testing phase, it is very difficult to go back and change something that was not well thought out in the concept stage. It is produced any work programs until late during the life cycle. High amounts of risk and uncertainty. Not a good model for complex projects and object-oriented .Poor model for a long and ongoing projects. Development Methodology Structured system Life Cycle: V-model Advantages: Simple and easy to use. Can test activities, such as planning, design, testing occurs well before coding. This saves a lot of time. There is a greater chance of success, so the waterfall model. I find any defects at an early stage proactively track the bugs. Avoid the downward flow of defects. It works well for small projects where they are easily understand the requirements. Disadvantages: Very rigid and less flexible. The program was developed during the implementation phase, so it is not production models at the beginning of the program. In the event of any changes in the middle of the road , and then along with test documents and documents and to update requirements Development Methodology Software and hardware development Life Cycle; Spiral-model Advantages: High amount of risk analysis, therefore, is reinforced to avoid risks. Good for large projects and mission critical. Strong approval and control of documents. You can add additional functionality at a later time .The program is produced early in the software life cycle Disadvantages: It can be expensive model to use. It requires a very specific expertise to analyze the risks. The project's success depends to a large extent on the risk analysis phase .It does not work well for small projects . Development Methodology Very extremes programming For the given CASE STUDY My Choice of SDLC + Methodology SDLC: waterfall Methodology: Reasons for my choice are; 1. Easy to use 2. Easy to understand and use 3. easy to manage because of the hardness of the model each stage has specific outputs and for the review process. 4. processed stages and finished at one time TASK 2 The REASONS for accurately capturing the functional requirements of a software system are; 1. 2. 3. 4. The STRATEGIES proposed for capturing the functional requirements of the system detailed in the CASE STUDY are; 1. 2. 3. 4. 5. 6.

A Merit or Distinction is awarded for higher level achievement. If all Learning Outcomes have not been achieved the work is Referred Where there is some doubt or concern regarding the origin of some of the content, the work is withheld. The student will then be interviewed to ascertain originality. When a Unit has been assessed Grades are reported on the Online E - Learning System. Students can obtain the grade awarded by viewing the Submission Inbox. Grades are reported according to the following; 50% indicates Pass 60% indicates Merit 70% indicates Distinction 30% indicates Referred 0% indicates Withheld A percentage mark within one of the boundaries indicates further work would be required to achieve the next highest grade e.g. 50% indicates that a Pass has been achieved, with additional work (according to the grade descriptors) a Merit could have been achieved. By viewing the Report the Originality can be obtained. Clicking on the GradeMark tab will reveal the QuickMark comments. Clicking on the General Comment tab will reveal the comments made by the Assessor and Internal Verifier NOTE • The Assignment Brief details all Assessment Criterions against which the coursework will be assessed • The Assignment Brief also specifically indicates which of the above grade descriptors have been incorporated within the activities to be assessed, in order that a student can achieve a Merit or Distinction. • Late and Very Late Submissions of the assignments are capped to Pass only.
