Stories often start out too big. Big stories are a challenge, and it is not always obvious how to deal with them. Its important that stories be small enough to estimate, to fit easily into an iteration and to have a decent definition of done. This article explores why some stories don’t fit this mold and what you can do about it.
Any of you people coming to Chicago for the Agile conference, here are a few of my wife’s and my recommendations for things to do in the the city. Most of these activities are within walking distance of the conference hotel.
Test Driven Development more than doubles the lines of code you have to write. With all that extra code to write, where will we ever find the time?! We have deadlines!
This is the third in my Deep Agile Embedded Panel Questions series. The question is:
We had a team doing agile. To them that included not doing any documentation. We need documentation once we go into maintenance. Is doing documentation allowed in Agile?
The short answer is yes. Agile does allow documentation. Do you think agile is a totalitarian dictator? 🙂
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”
Read on for some specific questions, and my answers.
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.
During my TDD session at the Embedded Systems Conference yesterday, I did a demo. Before the demo, I make the case for TDD as a way to prevent bugs (see Physics of TDD). For the live demo I usually code on my mac and run the tests there as well. The question always comes up: “You are running tests on your PC, can you run them on the target?” or maybe “Sure you can TDD on a PC, but what about the real hardware?”
Let’s say you were an embedded systems developer, and you were planning on attending a conference like the Deep Agile Embedded.
What questions would you hope you could get answers for at the conference?
What if you already knew it all but were sending your boss, co-worker, or CEO who needed to learn more, what would you want them to hear about?
Would you want to do some hands on Test Driven Development?
Here are some of the questions we have so far:
Every now and then I get a new automatic update. I usually just press install. Today I browsed the release notes for the Adium IM client update (below). There are six new features, denoted with a “*”. The rest (about 30 of them) are fixes, meaning something was broken. These guys must be too busy to proactively test Adium. Test Driven Development probably would not work for them 🙂
The Microsoft Zune 30G had a well known crash to bring in the new year. Here is the snippet of code that is the alleged culprit, from one of MS’s suppliers (Freescale).
