IT Assessment Answer

TASK: CASE STUDY PART 1 ISY00243 INTRODUCTION Eat Organic Food produces organically certified foods. It initially started by using Ian’s backyard. It was a large backyard...that had also made use of neighbors’ unused land. The business prospect has expanded in recent years with the return of Ian to his family property that historically has been used as a dairy farm. Although it was a major commitment, Ian has turned much of that land into a vegetable garden. He did not do this all by himself. He has employed farm hands to assist on the farm for several years. The range and volume of production and the number of customers is now making it difficult for Ian to keep track of things. An information system may provide a way to help manage the increasing complexities of the business. ACTIVITY 1 ISY00243 1. Use the background information to create a short summary (one short paragraph) about the “Eat Organic Food”. 2. Create an organisation chart for the business. 3. Use the information above to describe the area of the organisation under study (i.e. the business functions that will be handled by the new information system). 4. Add the background information, organisation chart, and business functions to your Report document in Part A: Initial Investigation. CASE STUDY PART 2 ISY00243 At your initial meeting, you and Ruth discussed some initial steps in planning an information system for the farm. The next morning, you worked together on a business profile, and talked together about various types of information systems that could provide the best support for handling their customers’ needs, and mindful that there was a need to also track certification documentation to demonstrate the fully ‘organically produced’ nature of the farm produce. You also discussed the longer term plan to expand the operations of the farm to include farms that supplied fruit, which would also have to be demonstrated to be fully ‘organically produced’. You start by creating a System Vision Document for “Eat Organic Food”, so that Ruth can use this to define a vision for the new system and present this to Ian. ACTIVITY 2 ISY00243 1. Either by yourself or with another class member, brainstorm all the functions that the “Eat Organic Food” Information System might fulfil. Keep it at a very high level. 2. Prepare a draft System Vision Document for the Farm Information System. This System Vision Document will be revised when you find out more about the requirements for the system. An example of System Vision Document can be seen in Figure 1.8 of the textbook (Figure 1.5 in the 6 th ed). 3. Add your System Vision Document to your Report document in Part A: Initial Investigation CASE STUDY PART 3 ISY00243 Ian has agreed that Ruth’s argument for an information system has merit. Your System Vision Document helped to demonstrate some of the potential benefits. Ruth wants you to get ready for the next set of systems development tasks, which will be requirements modelling for the new system. Yesterday Ruth called you into her office out at the farm to discuss the specific tasks she wants you to perform. After meeting with Ruth, you sit down and review your notes. She wants you to treat the set of tasks as a project, and to use project management skills to plan the tasks. Ruth is fully supportive of your involvement and excited that you carry so much practical knowledge in computer systems and that you are quickly learning about farming issues. Ruth is also excited that she too can become involved with her previous knowledge and skills in technology. A CTIVITY 3 ISY00243

• Create a table, listing all tasks separately, with their duration;
• Identify all dependencies, and indicate what predecessor tasks are required;
• Construct a Gantt chart in Microsoft Project or other project management software;
• Identify the PERT/CPM chart in the software, and identify the critical path;
• Determine the overall duration of the project;
• Take clear screenshots of the Gantt chart and PERT/CPM chart and paste into your Report document in Part A: Initial Investigation under Project Management.
• Include the overall duration and critical path in your report.

CASE STUDY PART 4 ISY00243 As a system analyst working on the development of a new system, it is your role to ensure that the project is feasible. Some of the reasons that projects fail are incomplete requirements, lack of executive and technical support, poor project planning and lack of required resources. At this stage, you decide to do an initial project feasibility analysis, to see whether “Eat Organic Food” should continue with its plan for the new information system. ACTIVITY 4 1. What are the risks associated with this project? Create a list of up to 10 risks and their likelihood of happening (see Study Guide topic 4, activity 4.6 for an example of how this should be set out). 2. Define the anticipated benefits of the new system. This should include both tangible and intangible benefits. Wherever possible, translate the intangible benefits into anticipated tangible benefits. 3. Define the expected costs of the new system. Look at the examples given in workshop activities for some examples of expense categories. It is OK to give estimates at this point. 4. Use two or more cost-benefit analysis techniques to decide whether to proceed with the project. 5. Identify any assumptions and interpretations that you are making with respect to the information that you have been given, that you are estimating, and that you are projecting (into the future). 6. Create a new section in Part A of your report: Risk and Cost-Benefit Analysis. Insert your work from above, and give a clear indication as to whether it is feasible to continue with the project. 7. Does the proposed system present a strong business case? Why or why not? Include a recommendation as to whether the system should proceed, as the final part of your preliminary report. The Preliminary Investigation part of your Report can now be submitted. CASE STUDY PART 5 ISY00243 You need interviewing staff with various job roles. This is part of the investigation is necessary to find out more about the requirements for the proposed system. ACTIVITY 5 1. What fact-finding techniques, apart from interviews, do you recommend to find out the requirements for the new system? 2. Include the recommendations for other fact-finding techniques, in your Report. Provide enough justification for using those techniques. 3. Identify at least two staff members with different primary job roles of interest to this project for interview. 4. Prepare a list of questions for an interview with each staff member. Identify the time anticipated for the interview. Review your topic on creating interview questions, and make sure you include suitable question types. 5. Include the interview plans (before, during, and after) in the Appendices for your Report. CASE STUDY PART 6 During requirements modeling for the new system, you met with the farm hands and owners of several farms who were in discussions with “Eat Organic Food” and intending to join as part of an expanded company, all coordinated in a direct delivery model to customers. Things were moving very quickly, and positively. You conducted a series of interviews, reviewed planting and harvesting records, observed business operations, analyzed the payment processes, and studied a sample of sales, billing and account settlement transactions. Your objective was to develop a list of system requirements for the proposed system that would unify the farms at a business level. ACTIVITY 6 1. Write down a list of the main functions needed to be handled by the new system. 2. What are the roles that will be interacting with the system? 3. Write down a list of additional features which in principle could be included in the new system, but are more likely to be held back for now and considered in the “Eat Organic Food” Case Study ISY00243 future if and when the resulting information system is subject to later review and enhancement(s). Include the list with appropriate descriptions in your report. 4. Using all the information that you know about the EOF business so far, create a use- case diagram (with all actors/users and use cases) for the new system and include it in your report. You may provide enough explanation about the use case diagram. 5. Select four use-cases and write a brief use-case description for them. Pick one of these use-cases and write a full use-case description for it. Draw and use an activity diagram in the full description. You need to have the following in your report: ? use case list and descriptions ? the use-case diagram and its explanation ? brief use-case descriptions for 4 use-cases ? a full use-case description ? an activity diagram
