Process patterns example: driving 7/5

  • Processes can be classified by their sophistication
  • Following Freedman and Weinberg, there are six patterns of sophistication
  • Let’s do an example — the process of driving a car:
What’s “driving”?
We drive wherever we want to go at the moment
We know how to use the steering wheel, we know the recommended routes, and we do the right thing (except when we panic)
We have several routes, and we choose from them according to conditions at the time
We consider the predictions for weather, traffic, construction, etc., when we’re deciding our route
We’re always improving everything, including steering wheel technology, weather, and traffic prediction … we’re even improving how we improve

These patterns are useful for analyzing the sophistication of almost any process.

Part of managing a model development process is knowing where you are. Is your process Variable? Routine? If you know the level of sophistication of your process, you have a better idea of what to expect from it in terms of predictability, quality, and so on.

Most organizations that use spreadsheet models to support business decisions are at the Variable or Routine level. This is most ironic, because the level of sophistication of their other processes is often quite high.

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.
