A Use Case Description Tutorial For The Business Analyst

What Are Use Case Studies?

The purpose of Use Case studies are to show the situation(s) in which a program is going to be used by the end user.

It is like a story board in that it tells a story, describing how the program is going to work and the input of the user.

A Use Case does not document how the program is developed. There is also no detail about any of the programming. The aim is to express the concept behind the creation.

The Types Of Use Case Study

Generally a use case comes in two types, which are:

1.The essence use case

This is created at the beginning of the project. Its purpose is to show what a program is going to do. With this case there are no technical terms or jargon used, or mention of any programming.

2.The Real Use Case

This will give you a more hands on description of the application. There will be slides which show how the system is to be operated. The Real Use Case is put together mid-way through the programs development.

The real use case will give the stakeholders a glance of how instrumental the program will be.

It allows the stakeholders to see the users interactions with the system and then suggest improvements.

The Use Case is the best way to communicate to the IT department what the system will be used for. It describes in a hands on manner how the application will be used within the system.

It allows everybody the chance to know what will be expected when the program is complete.

The case study will allow stakeholders, the IT department and end users the chance to be satisfied before completion and outcome of the project.

Use Case Studies For More Than Just Scenarios

It’s also important to note that a Use Case study can be more than just a means to show scenarios of an application. They can also be a pivotal part of training and crucial documentation.

After the project is done the end user or stakeholders may want to keep the Use Case studies for a guide to help develop training manuals. This is great news for the business Analyst that takes the time to present the use case studies clearly and succinctly.
