Prior to the Deep Agile conference, I received a number of questions about getting people to change, to try new things. Change is hard. People need to be motivated to change. “If it ain’t broke, don’t fix it” they say. But there is always some things that are broken.
First there needs to be awareness/acceptance that there are problems to solve. Do a retrospective of the last release. Find the problems that people are passionate about. Try not have blame session. Build a logic chain from the problem to some solution you think will help. Get people to sign up to try the new approach for a month or two, not the rest of their lives. Iterations give a great opportunity for this kind of experimentation.
You have to try things, rather than just talk about them. I am not sure where this quote is from, but it is profound:
“It’s easier to act your way into thinking differently than to think your way into acting differently”
Last weekend was the Deep Agile Embedded Conference that I participated in. In this article I’ll answer some of the panel questions related to concurrent hardware development. There seems to be a theme here, because the hardware is involved, an embedded development team really can’t be agile. That’s not my point of view, or my experience. I am not a hardware engineer, but I have worked near them. Let’s see some of the questions and answers. Continue reading →
Coupling and cohesion have been discussed for a long time as the right criteria for judging a design. But there seemed to be no objective way to determine if code exhibited those qualities. Could TDD lead to higher cohesion and loose coupling? Continue reading →
I’ve been talking Agile at the Embedded Systems Conference. Last week was my 7th year of participation. A few common questions usually come up. I’ll paraphrase the questions and answers. Continue reading →
I keep hearing that you can’t write unit tests for device drivers. I don’t believe that’s true. To disprove this claim, I thought I would find a device driver and write some unit tests for it. This blog posting shows what device driver unit tests look line.
