Agile and the Theory of Constraints – Part 3: The Development Team (1)

Thu, 16 Feb 2017 15:54:53 +0000

(Note: this post has gotten far too long, so I’m going to break it into parts. Or subparts, I guess) A few notes before we start: I’m using “feature” because it’s more generic than terms like “story”, “MVP”, “MBI”, or “EBCDIC” I picked an organizational structure that is fairly common, but it won’t be exactly...

Trip Report: Agile Open Northwest 2017

Tue, 14 Feb 2017 16:46:26 +0000

Agile Open Northwest uses a different approach for running a conference. It is obviously around agile, and there is a theme – this year’s was “Why?” – but there is no defined agenda and no speakers lined up ahead of time. The attendees – about 350 this year – all show up, propose talks, and...

Stop writing bad tests. Write only the tests that you can do great.

Sun, 09 Oct 2016 20:25:15 +0000

I’ve been working on a talk on ways to make unit testing easier. I has not been going well; I’d come up with an approach I liked, do most of the slides for it, come back to it, and be unhappy with what I had written. This happened – and I am not exaggerating –...

You Suck at TDD #8 – Doing fewer things

Tue, 05 Jul 2016 15:05:33 +0000

Welcome back to You Suck at TDD. Today’s code will show up in the Improvements-Phase-3 branch if you would like to follow along. In our last episode, we concentrated mostly on the Employee fetching and filtering. Things are better, but we still have a problem… Well, actually, we have a number of problems, but we’ll start...

Agile and the Theory of Constraints – Part 2: The development cycle

Tue, 17 May 2016 15:18:44 +0000

In the last post, I talked about some of the analysis used in lean. Now, let’s see how we can apply the same principles to the software world. I will start by trying to create a value-stream map. But where to start? There are three levels at which we can do the mapping: The entire organization,...

Agile and the Theory of Constraints – Part 1

Mon, 25 Apr 2016 04:52:35 +0000

I’ve been spending some time over the past few months exploring the lean side of the house and looking for things I can adapt into the agile side of the house. The most interesting thing I found was the theory of constraints. After spending some time writing this, I realized that I need to split...

Doesn’t pairing cost twice as much?

Tue, 05 Apr 2016 23:02:07 +0000

(I was recently involved in a discussion about pairing, and I think what I wrote will be of more general interest.) Many teams evaluate pairing from a simple mathematical perspective. Total work done = # of team members * amount of time spent working If you want to increase the amount of total work done, then...

You Suck at TDD #7 – Improvements Phase 2

Sun, 27 Mar 2016 18:20:33 +0000

All changes from this post are in the Improvements Phase 2 repo… Commits that start with “R:” are done through Reshaper. I’ll cluster them together this time. R: Start of Phase 2 Last time, I created the EmployeeFilter abstraction and populated it with code from the GetEmployees() method. That was a pretty typical refactoring to...

You Suck at TDD #6 – Improvements Phase 1

Tue, 15 Mar 2016 15:13:51 +0000

Welcome to the first post on improving the yucky code. I have a few points I’d like to cover briefly, and then we’ll dive into the code. First off, I’m going to end up refactoring to a specific endpoint, but that is not necessarily the only endpoint or even the best endpoint. Not only are...

You Suck at TDD #5 – Homework

Thu, 10 Mar 2016 16:17:32 +0000

It is now time for me to turn the tables on you, to present you with some homework. If you take a trip to my Github account, you will find the following lovingly crafted repo. In it, you will find some yucky code. It’s not terrible code – in fact, it’s pretty average code from my...
