The Case for and Against Estimates, Part 5

If you’ve been following the conversation, I discussed in Part 1 how I like agile roadmaps and gross estimation and/or targets for projects and programs. In Part 2, I discussed when estimates might not be useful. In Part 3, I discussed how estimates can be useful. In Part 4, I discussed #noestimates.  Let me summarize […]

The Case for and Against Estimates, Part 4

When we think about the discussion about estimates and #noestimates, I have one big question: Where do you want to spend your time? In projects, we need to decide where to spend our time. In agile and lean projects, we limit the work in progress. We prefer to spend our time delivering, not estimating. That’s

The Case for and Against Estimates, Part 3

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

The Case for and Against Estimates, Part 2

In the first part of this series, I said I liked order-of-magnitude estimates. I also like targets in lieu of estimates. I’ll say more about how estimates can be useful in part 3. In this part, I’ll discuss when I don’t like estimates. I find estimates not useful under these conditions: When the people estimating are

The Case for and Against Estimates, Part 1

After the article I referenced in Moving to Agile Contracts was published, there was a little kerfuffle on Twitter. Some people realized I was talking about the value of estimates and #noestimates. 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

Velocity is Not Acceleration

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

Value of Burndown and Burnup Charts

I met a team recently who was concerned about their velocity. They were always “too late” according to their manager. I asked them what they measured and how. They measured the burndown for each iteration. They calculated the number of points they could claim for each story. Why? Because they didn’t always finish the stories they

Creating Great Estimates as a Team

I’ve been teaching workshops these last few weeks. A number of the participants think that they need to create great estimates. I keep hearing, “I have to create accurate estimates. My team needs my estimate to be accurate.” I have found that the smaller the work, the better the estimate. If people work as a team,

Great Review of Predicting the Unpredictable

Ryan Ripley “highly recommends” Predicting the Unpredictable: Pragmatic Approaches to Estimating Cost or Schedule. See his post: Pragmatic Agile Estimation: Predicting the Unpredictable. He says this: This is a practical book about the work of creating software and providing estimates when needed. Her estimation troubleshooting guide highlights many of the hidden issues with estimating such as:
