Early on when trying to apply Agile methods to software development I found a lot of the challenges were in the area of software testing. Not just because a lot more automated testing was being done, but because requirements would shift and change rapidly. Many levels of rapid feedback needed to be in place to ensure the development didn’t misstep for too long.
I started exploring more places a focus on testing and quality could be applied. And that led me on a journey earlier and earlier in the development timeline.Continue reading “Testing as a Holistic Exercise”
There is a famous experiment in behavioural science called the Marshmallow Experiment. In the simplest version of this experiment they sat down a child in front of a marshmallow, the instructor told the child that if they sat there and waited the instructor would come back with an additional marshmallow and they could have both. However if they took the one marshmallow before the instructor returned then that was all they would get. Once the child understood the instructions they were left alone for 15 minutes.Continue reading “Avoiding Giving Advice”
In a recent assessment of people applying for graduate and intern positions at my work we wanted a way to quickly assess them as a group. Ideally we wanted to see their individual skill at work, how well they worked with others and all in under an hour for groups of up to five. So I suggested we get them to do some Mob Programming on a Kata exercise. It wasn’t something we tried before but the idea wasn’t completely out of the blue.Continue reading “Pair and Mob Programming for Interviews”
My go to tool in coaching is to ask a question. I used to try and give people advice but I learned that no one listens to uninvited advice. Telling people want to do can work in a position of authority but they wont take the time to ask why you want them to do it differently and are happy to abandon it all when you leave. So I take a different approach and ask them about what they are doing already.Continue reading “Dumb Questions”
My team has a challenge that I haven’t run into before. We all want the code to be better quality that it is now. However we don’t agree on what “better” is.
Even simple things can lead to long discussions and debates so it was a struggle to get some serious progress. Reviews could get bogged down because a refactoring someone did triggered a debate on its merit. We needed a format to allow us to work through some of the fundamentals and find where there was consensus. So I booked us in to do some mob programming together except we were not going to write new code. We were going to focus on only refactoring.Continue reading “Learning Refactoring Together”
It’s been interesting over the last year for me as I explore where coaching for software teams and coaching for sports people overlaps. This year I got to be coach for a Roller Derby team which is the first time I’ve called myself a coach for more than a brief workshop. In my day job I’m involved in many activities that have nothing to do with coaching so I rarely call myself an Agile Coach. But to that sports team I am the coach. And while I’ve been involved with Roller Derby for 5 years I have very little training in coaching sports teams so I started applying all the things I’ve learned coaching software teams.Continue reading “Coaching is a Transferable Skill”
We had a discussion at work after watching the excellent Kelvin Henney talk about good unit tests. And it helped me clarify the many roles tests play and why people get a habit of complaining about their tests getting in the way. So here is the four categories a test is trying to balance:

Last year I got to attend a workshop on the Toyota Kata by Hakan Forss and I could immediately see how it could be useful but I didn’t have an obvious place to apply it until recently. We got some good experience with the concept using jigsaw puzzles in a group.Continue reading “Applying the Toyota Kata”

How lean coffee works: A few people from work got to take part in one at Agile Australia but I missed it myself. So I just got online and read everything at http://leancoffee.org/ I grabbed a bunch of index cards and texters and was ready to go.Continue reading “Things I’ve Learned from Running Lean Coffee”
I spend a lot of time working closely with programmers on the software testing process. Much of my career mission is to get more people embracing techniques like Test Driven Development. As I push more and more of the testing demands onto the developers I sometimes run into people who say they need a tester for “independent testing”.Continue reading “Can Programmers Test?”
