Design the Path for the Success Case

When you are designing a process branch, focus first on the path for the success case. This is the case in which everything goes forward successfully with no interruptions.

The success case follows the "80 percent rule:" this is what happens 80 percent of the time. The other 20 percent are exception cases.

To design the success case, you need:

• Good requirements gathering and analysis
• Communication with the end users of the process

The end users for the success case are typically the primary stakeholders for the process branch from whom you will gather the requirements.
