Requirements management 7/22
Session Links
  • Requirements are the properties the model must have
  • Purposes of requirements management
    • Establish common understanding between sponsor and modeler
    • Make a clear statement of “where we must go”
  • Requirements provide basis for project planning

Pattern 2: Routine

“Requirements” can be difficult to define. But here’s a simple operational definition: the requirements of a model are the minimum set of capabilities without any one of which the model would be considered a failure. For example, the requirements for a bridge should probably include both the maximum load it can support, and the number of travel lanes it should have.

The requirements should be settled on before any development begins. If you try to change them after work starts, you can end up having to rework some of what you’ve already done. This is the basic reason why requirements practices are so important.

Inspect Your Project Early

Many believe that the main benefit of spreadsheet inspections is that they locate issues so they can be fixed. Certainly they do accomplish that. But spreadsheet inspections, when performed early enough and often enough, can actually prevent problems. And preventing problems is certainly more valuable than locating them.

We hope that you’ll apply what you learn about spreadsheet inspections when you work on your projects. If you’re working in a team, review your project schedule and decide when would be advantageous times to insert an inspection or two. If you’re working alone, ask someone else who’s working alone if they would be willing to inspect your project in exchange for your inspecting theirs.

Since we don’t grade on a curve, helping someone else doesn’t hurt you. Inspection exchanges raise the quality of both projects — and both grades. Whatever you do, don’t wait until the end to do your inspections.
