This is the start of a multi-part series on my favorite requirements elicitation technique: the Business Event/Response Analysis. Early versions of this methodology were developed in the late 1980’s by some of the great system development minds of that era. Since then it has evolved and I have adapted it to meet the needs of whatever organization for which I am working.

There are some that think you can gather requirements by just asking the sponsors and users “what do you want?”. Needless to say, this method will generate incomplete requirements and tends to start and end with functional requirements. In the latter half of the project when large requirements gaps are discovered, the sponsors/users blame the analyst and vice versa.

When I teach on this topic, I tell the analysts it is their responsibility to gather complete requirements. Given this, we need a method that will (1) generate the appropriate questions to ask, (2) ensure that we have the complete set of requirements, and (3) allow us to derive the functional requirements from the model.

The Business Event/Response method meets these desired outcomes. The advantages are:

• It helps the Business Analyst create the questions needed to draw the requirements from the Business Owner, even if the Analyst has no knowledge of the business area.
• It organizes the requirements in the context of Business Processes and Usage to promote better understanding.
• The output serves as a starting point for defining the testing scope and scenarios.

In the upcoming posts I will describe this method in detail.
