Estimation Alternatives, Part 1: Feature Budgets

by

A powerful estimation alternative is to treat project funding as a budget and charter teams to spend it effectively.

The most common question on any project is, “How long with this take?” This question isn’t too difficult to answer when the work is small – a few minutes to a few days. Problems start when someone wants an estimate for a chunk of work you can’t complete in just a few days. Requests for estimates like this come from a need to make higher-level planning decisions. But estimates aren’t the only way to make these decisions. Over the last fifteen years of working with agile teams, I’ve seen value in exploring estimation alternatives. Two, in particular, come to mind, the first of which I’ll describe here: Shifting conversations about estimating to budget discussions.

The Secret to Backlog Refinement (and Five Bonus Tips)

by

Antique key in a keyhole“What’s the secret to backlog refinement?”

Eighteen pairs of eyes turned to look at me, waiting for my answer to this product manager’s question. I’d spent the last two days with the group working through the challenges they faced using Scrum in their company. We discovered that most of their delivery problems stemmed from the teams not understanding what was needed. They’d identified with the story I’d told about the team that hated Sprint Planning and hit the reset button on their process. They knew they weren’t doing refinement and could see the effect. They wanted to know how to make it work for them.

How to Improve Transparency and Flow in Your Team’s Work

Water flowing over rocks in a mountain stream.
Teams should expect surprises to happen – even if they don’t know exactly what or when. Agreements about how to manage challenges when they do occur can keep them from disrupting the team’s flow.

The team was struggling. They were working on an industrial motion control product, porting a legacy code base to a new hardware platform. Parts of the code were decades old, and many of the original developers no longer worked at the company. They kept getting stuck trying to figure out how the code worked and what they needed to do to make it work in the new system. Neither the engineers nor the product manager had visibility into what was taking so long or how to help.

Scrum Commitment or Forecast

by

I’ve been training, talking, coaching, and writing recently on the topic of commitment and realized that anytime that comes up, it reminds me of the old (seems old – but not really that old!) discussion on commitment or forecast. I still find there are many questions on this topic. It certainly has not been put to bed. The approach I like to take is to step back and ask “what is the real problem?”  Is a word stopping you from succeeding or is something else causing the problem?  What am I talking about? — I’m talking about when the Scrum Guide was updated to change commit to forecast.

Agile Area Rugs- Covering Opportunities with Longer Sprints?

by

Will longer agile sprints or iterations cover up opportunities to improve and cause you to view these opportunities as unsolvable problems?

The typical agile sprint size is 2 weeks. What percentage of teams use 2 weeks?  I don’t have statistics on it, but I’d guess over 90%.  I’m working on a product where we are doing 1 week sprints.  It’s a startup and things are changing a lot so 1 week works well.  I also know some teams that use 3 week sprints and it is working for them.  I’m not saying it has to be a certain number of weeks – but please don’t kid yourself with what length will actually work for you.

I’ve seen situations where people are doing 3 week sprints, but then have a 1 week “hardening” sprint.  Personally, I’m not a big fan of hardening sprints.  I can see many “logical” arguments on why people need them, but in the 3+1 week sprints – I’d say stop kidding yourself.  You have a 4 week sprint!  Maybe that is the best you can do right now and you are ACTIVELY working to eliminate the hardening sprint – but if you believe you will always need one you are likely stuck.
