Posted February 24, 2020 by Tim Ottinger in Learning

The manager looks across the room at the team members. It’s 8:45 and everyone should be in attendance. Where’s Rob? Surely he’s not still at his desk? “Okay let’s start on the left and go around the room,” the manager says, as she always does.

Posted February 17, 2020 by Tim Ottinger in Learning

I’m going to be using a metaphor that not everyone can relate to since not everyone is on a speaking circuit. My hope is that this metaphor will teach you two things: how to plan a conference talk, and how to approach doing big things quickly.

Estimates vs Actuals

Posted February 11, 2020 by Tim Ottinger in Learning

“Oh, no! We estimated 23 story points for the sprint, but we only turned in 20. We’ve failed the sprint!” It seems that a lot of teams, especially scrum and SAFe teams, are spending a lot of time on story point estimates. This is understandable, and also disappointing. You see, you can’t estimate your way […]

Are tests valuable?

Posted October 31, 2018 by Jessica McCay in Learning

During my time as a developer, I have come across wildly differing opinions on testing. Many would say that you absolutely, without a doubt, should write tests around the code you write. Others felt that testing was a waste of the developer’s time and energy. When I first began programming, I did not like writing […]

Posted October 18, 2018 by Mike Rieser in Coaching, Learning

A team is asked to take on a special project but they feel uneasy because they lack all of the skills necessary for a successful outcome. Have you experienced that problem before?

How long is too long for a build?

Posted July 6, 2018 by Brett Schuchert in Continuous Delivery, Learning

Synopsis Short builds enable responding to change, continuous code improvement, and keeping your customers happy. When the build slows beyond certain thresholds, there are predictable responses by a team that lead to slower builds, lower code quality, and continuous code rot. We’ll look into why this is, why it is worth investing in speeding up […]

Mob programming is great stuff! We have found it to be the best way (so far) to teach technical skills to teams of programmers, and the best way for them to continue developing and teaching their skills well beyond our workshops. Here are a set of tips that help us to make mobbing more successful […]
