For the purpose of this analysis approach, “Business Events” are anything that occurs that causes your “business” to initiate a business process. Defining all of the Business Events in scope will lead to discovery of the business process in scope.
There are three main types of Business Events:
- External: These come from outside of your business and you have little or no control as to when or how often these events occur. Examples are “Customer purchases Product” or “Associate requests time off”.
- Temporal: These events happen at regular predetermined intervals. These intervals are required, they are not a business or design decision. Don’t let technology limitations determine the interval. Good Example: “It is time to file quarterly taxes”. Bad Example: “Every two hours the HR system sends employee information to the Financial System”.
- Data/System State: Occur when the data or system reaches a predetermined condition. These are usually Business Rules or Policy decisions. Example: “Product is re-ordered when the inventory level reaches 5”.
The input arrows on the Context Diagram are the starting point for event discovery. In the next post I will define the elements of the “Event List”.
