Case Study 1 - Henry's Organics produces organically certified vegetables, fruit and nuts, honey and eggs that are grown with permaculture principles and biodynamic soils. It initially started inHenry Cropper'sbackyard. He and his friends started a community garden, and due to increasing demand for locally grown organic food, it has grown into a commercial venture.

ACTIVITY 1
1. Use the background information to create a short summary (one short paragraph) about the "Henry's Organics".
2. Create an organisation chart for the business.
3. Use the information above to identify 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 2 - At your initial meeting, you and Belle 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 alsotrack certification documentation to demonstrate the fully ‘organically produced' nature of the farm produce.

ACTIVITY 2
1. Brainstorm all the functions that the "Henry's Organics" Information System might fulfil. Keep it at a very high level. E.g. a Functional Chart and/or ideas from Lecture 1.
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 System Vision Document can be seen in Figure 1.8 of the textbook or Lecture 1 slides.
3. Add your System Vision Document to your Report document in Part A: Initial Investigation.

Case Study 3 - Henry has agreed that Belle's argument for an information system has merit. Your System Vision Document helped to demonstrate some of the potential benefits.

Bellewants you to get ready for the next set of systems development tasks, which will be requirements modelling for the new system. YesterdayBelle called you into her office out at the farm to discuss the specific tasks she wants you to perform. After meeting with Belle, 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.

ACTIVITY 3
1. Create a table, listing all tasks separately, with their duration;
2. Identify all dependencies, and indicate what predecessor tasks are required;
3. Construct a Gantt chart using project management software (see the suggested resources);
4. Using PERT or CPM identify the critical path;
5. Determine the overall duration of the project;
6. 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.
7. Include the overall duration and critical path in your report.

CASE STUDY PART 4 - As a system analyst working on the development of a new system, it is your role to ensure that the project is feasible

ACTIVITY 4
1. What are the risks associated with this project? Create a list 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, along with the information from the lecture on how to complete the analysis).
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 the 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 andinterpretations 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 proceedas the final part of your preliminary report. The Preliminary Investigation part of your Report can now be submitted.

ACTIVITIES FOR REPORT PART B

CASE STUDY PART 5
You need to interview staff of various job roles at Henry's Organics. 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 for finding out the requirements of 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 modelling for the new system, you met with the farm hands and owners of several farms who were in discussion with Henry's Organics 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.

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 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 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 need to provide enough explanation about the use case diagram.
5. Select four use-cases and write a brief use-case description for them.
6. 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.
7. 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

CASE STUDY PART 7
You have been preparing the System Requirement report for Belle and Henry. From your investigation so far, you are leaning towards a recommendation for either in-house development or outsourcing options for the new system. You do not feel that a commercial software package would meet the needs of the farm, but you will investigate this option further.

ACTIVITY 7
1. Review the NLA fact-finding summary and all other information you have about the required system and critically analyse this for duplications and inconsistencies.
2. Draw an ERD diagram with crows-foot cardinality as well as a domain model class diagram with notation. Assume that system entities include farms, customers, status as Regular or Variable, orders, vegetables with associated price per unit, and delivery person (at minimum), as well as organic certified.
3. Design tables - making sure each table only refers to one "thing". As you create the database design, identify primary and foreign keys by underlining primary keys, and making foreign keys italic.
4. If you add primary keys which use codes - for example a code for the farmID, then identify the format of these codes.
5. Create suitable sample data to populate the fields for at least three records in each table.
6. Include the following in your report:
• The ERD or domain model class diagram you have completed;
• The database design (schemas);
• Formats of codes used;
• Sample data for each table.

CASE STUDY 8
You are now making sure that you have sufficient models to understand the new system. In reviewing the models (use-cases diagrams, including activity diagrams) you realise that you have not included a system sequence diagram for any of the use cases.

ACTIVITY 8
1. Create a system sequence diagram for one of the use cases identified in Activity 6.Add this system sequence diagram to your report in the appropriate area.
2. Search online for potential commercial software packages for Henry's Organics. Identify two packages, and compare their features, and their suitability to be used as the new system.
3. Present at least three options for the new system in your report. One of these must be in-house development, and two of the others may be the commercial packages as identified in (2) above.
4. Review your feasibility analysis for the new system. Taking all options into consideration, make a recommendation for the new system, in your "Conclusion and Recommendations" section.

You have completed the contents of your report, and now need to make sure that the report is presented professionally, as it will be shown to Henry, Belle and owners of farms intending to work with Henry's Organics, as well as any potential investors in the new system, and the expanding prospects for Henry's Organics.

ACTIVITY 9
Ensure your report is professionally presented. This means your report should include:
• a title page, with the name of the Report, and the analyst's name (your name);
• an executive summary;
• a table of contents, with page numbers;
• page numbers on all pages except the title page;
• Headings, sub-headings, dot-points and numbering where necessary. Headings should be numbered or the structure should otherwise be easily identified;
• Appendices where necessary;
• Formatting and whitespace (space where there is no text or pictures) used appropriately; (Be willing to start each new section on a new page);
• Page orientation used appropriately. For example, if you have an ERD that will show better in landscape orientation than portrait orientation , set a Section break (Page Layout > Breaks) before this page, set the page to landscape and then set another Section break to start the new page in portrait again.
