In Part 1, I discussed order-of-magnitude estimates and targets. In part 2, I said how estimates can be misused. In this part, I’ll discuss when estimation is useful. Here are several possibilities: How big is this problem that we are trying to solve? Where are the risks in this problem? Is there something we can do to manage the risk ...

The Case for and Against Estimates, Part 1

Some folks thought I was advocating never estimating anything. Let me clarify my position. I like order-of-magnitude estimates. I don’t hire people without either a not-to-exceed or an ...

When is Agile Wrong for You?

agile-logo

People often ask me, “When is agile  right or not right for a project?” I’ve said before that if the team wants to go agile, that’s great. If the team doesn’t, don’t use agile.

Velocity is Not Acceleration

agile-logo

I see a lot of confusion around velocity in new-to-agile teams. Too many people treat velocity as an acceleration measurement. That is, they expect velocity to increase to some large number, as a stable state. Velocity is a rate of change coupled with direction. When managers think they can measure a team with velocity, they confuse velocity with acceleration. As I enter ...

Resource Efficiency vs. Flow Efficiency, Part 2: Effect on People

agile-logo

If you haven’t read Resource Efficiency vs. Flow Efficiency, Part 1: Seeing the System,  I explain there about optimizing for a given person’s work vs. optimizing for features. Some people (including managers) new to agile have questions about working in flow vs. optimizing for a person. The managers ask: How do I know the work won’t take longer if we ...

If you’ve read Reasons for Continuous Planning, you might be wondering, “How can we do this?” Here are some ideas. You have a couple of preconditions: The teams get to done on features often.
