It’s easier than you may think. And when you learn to create use cases more effectively, you’ll experience multiplying success as a business analyst.you’ll experience multiplying success as a business analyst.

In fact, here are three ways to do it:

For individual stakeholders, use a three-part use case system.

To simplify the use case development process, use this model: position, need, reason.use case development process, use this model: position, need, reason.

For example, as an IT firm manager, I need to protect my companys computer from hacking and malware attacks, because there is sensitive data that could compromise my business.

Position: IT manager

Need: Security

Reason: Sensitive Data

In using the model to create better use cases, you can create a solution-based approach that concentrates on the big picture, instead of small parts of a whole. When you use this system, you’ll find that writing use cases becomes vastly easier.

Please note: this model works best for an individual stakeholder, not a complete organization; however, it’s important to note how the IT manager’s problem impacts the entire company.

A group session brings the whole picture together.

During the requirements elicitation phase, a group session helps you determine a collective consensus. As you put your feelers out for requirements, go beyond the individual level, and place your focus on what the entire organization needs from you.

If a group session is not an option, you’ll need to go from office to office in order to create the most thorough report. It’s best to avoid this situation by telling your stakeholders that a group session would provide the greatest benefit because:

  • You may find hidden problems.
  • You’ll understand what stakeholders experience.
  • You’ll see the big-picture solution.
  • You’ll have synergy as a group.

Work as a BA team.

If you’re working as a team, don’t be afraid to call a meeting between BAs. When you create a collaborative use case, you’ll add details that make the project run more smoothly.

According to the IIBA, this is not the best way to complete use cases. In their thinking, team efforts lack a representation of all stakeholders involved.

However, if you include multiple stakeholders and decision makers, and take your use case idea session past the brainstorming phase, you’ll find that team development of use cases can work.
