Use Case

Description: 

A use case is a set of instructions that an individual in a process completes to go through one single step in that process. It describes what the user does to interact with a system.

Uses: 

To understand how a user is aided by a system when completing a specific task.

How do I use this tool?: 

1. IDENTIFY A PROCESS AND A SCENARIO within that process (the use case) to be analyzed.

2. IDENTIFY STAKEHOLDERS AND KEY PLAYERS in the use case.

3. DETERMINE THE GOAL(S) to be achieved from the analysis. Generally the goals of the use case revolve around identifying event triggers, alternate scenario paths or extensions, or simply just to understand the process and scenario better.

4. COLLECT RELEVANT DATA that will aid in achieving the goals of the use case identified in the previous step.

5. ORGANIZE THE COLLECTED DATA in a manner which best supports the use case goals.

6. SUMMARIZE AND FORMULATE CONCLUSIONS.

Expertise Required: 
Users of this tool usually have some training or experience in its use.
Advantages:

Disadvantages: 

Clinical background is necessary for good results in health care settings.
