I have a new article up on agileconnection.com called The Case for #NoEstimates. The idea is to produce value instead of spending time estimating. We have a vigorous “debate” going on in the comments. I have client work today, so I will be slow to answer comments. I will answer as soon as I have […]
I have an article up on agileconnection.com. It’s called How Do Your Estimates Provide Value? I’ve said before that We Need Planning; Do We Need Estimation? Sometimes we need estimates. Sometimes we don’t. That’s why I wrote Predicting the Unpredictable: Pragmatic Approaches for Estimating Cost or Schedule. I’m not judging your estimates. I want you to consider
I am doing a google hangout with Marcus Blankenship on April 10. We’ll be talking about estimation and my new book, Predicting the Unpredictable: Pragmatic Approaches to Estimating Cost or Schedule. The book is about ways you can estimate and explain your estimates to the people who want to know. It also has a number
For years, we bought the cone of uncertainty for estimation—that is, our estimates were just as likely to be over as under. Laurent Bossavit, in The Leprechauns of Software Engineering, shows us how that assumption is wrong. (It was an assumption that some people, including me, assumed was real.) This is a Gaussian (normal) distribution.
Many organizations create teams by their architectural part: front end, back end, middleware. That may have worked back in the waterfall days. It doesn’t work well when you want to implement by feature. (For better images, see Managing the Stream of Features in an Agile Program.) Pierce Wetter wrote this great article on LinkedIn, There is
As I write the program management book, I am struck by how difficult it is to estimate large chunks of work. In Predicting the Unpredictable and Manage It!, I recommend several approaches to estimation, each of which includes showing that there is no one absolute date for a project or a program. What can you do?
I’m writing part of the program management book, talking about how you need to keep everything small to maintain momentum. Sometimes, to keep your work small, teams move from iterations to flow. Here are times when you might consider moving from iteration to flow: The Product Owner wants to change the order of features in
Cesar Abeid interviewed me, Project Management for You with Johanna Rothman. We talked about my tools for project management, whether you are managing a project for yourself or managing projects for others. We talked about how to use timeboxes in the large and small, project charters, influence, servant leadership, a whole ton of topics. I
Do you have projects where you can’t predict an end date? These tend to be a job search, a change project, and with a tip of the hat to Cesar Abeid, your life. I like to call these “emergent” projects. You might prefer to call them “adaptable” projects, but to me, every project has to
This post is continued from Cost, Value & Investment: How Much Will This Project Cost, Part 1 We’ve established that you need to know how much this project will cost. I’m assuming you have more than a small project. If you have to estimate a project, please read the series starting at Estimating the Unknown:
