Assume you are a systems analyst and you have been asked to develop the information system described in the case study provided for this question or any other case study, including but not limited to the veterinary case study used in class:

a) Describe three use case scenarios

b) Using use cases, model the system expected from case study

c) For one important use case, develop a basic flow of events and one alternate flow of events

Case study:

The case study describes a dairy farm management system for small scale farmers. The systems main functionalities are:

Animal control, Stocking and capital expenditure: This is where recording of the cost of animal acquisition or farm inputs take place.

Human resource management: allows for capturing of human resource details such as their national identification numbers, worker earnings, names and cadre.

Animal production management: Farm produce is captured per unit of production. For example, in a dairy farm, milk recording is done per cow hence monitoring production per animal per milking session.

Consumables recording: Alongside stocking and capital expenditure, there is need to capture routine consumables.

Equipment: The acquisition of farm equipment is recorded as capital expenditure. Once acquired, records for maintenance and servicing are captured through the equipment module.

Document Management: allows for scanning and uploading of documents using phone camera. Uploaded documents may be restored on need basis and used as proof of expenditure or income. .

Buyer registration and rating: allows for buyers to be registered so that in case they are identified as not being fair, they could be reported to other farmers.

Reporting: users can generate simple reports from the various core functionalities.
