Book Review: Agile Game Development With Scrum

Staying on this Agile game development interest, I was at the local book store the other day and ran across the book Agile Game Development With Scrum by Clinton Keith and thought, “how appropriate”. Needless to say I was intrigued about the aspects of applying Agile directly to game development and immediately started reading it.

One of the elements that Keith keeps repeating throughout the book is that there are “no silver bullets” and adopting Agile won’t save a team already on a death march schedule, nor will it allow a team to handle an impossible schedule. What Keith proposes instead, is that Agile will give a team a framework to learn about scheduling issues, current velocity and burn down charts as well as processes to detect potential issues with the schedule or design, far earlier in the project.

The main point that I found crucial to success, was the idea of cross domain teams. A couple artists, level designers, game programmers, server programmers etc. would form a single team responsible for part of the game, and would handle all aspects of that feature, while iterating over the different stages every two week sprint. Adopting this team structure, I feel, would be a huge boon to any game dev work place as the slowest part of any game is always (always!) cross team integration. Here are two examples of what could happen in a non-cross domain team:

1. An artist creates an asset and has no developer support to test it. Without integration they go on to make multiple assets the same way spending weeks (or months) of effort, only to find out later they need to modify all their assets now that dev has begun testing them.

2. Server team creates APIs for client, but no client team is available to test them. Server developers go off and create new APIs. Once the client begins testing the APIs they find they need to add additional parameters and/or bug fixes. This requires days of rewrites from a different developer, since the original author is working on another critical section and is not available to update the code.

I see these kinds of issues happening over and over again in large scale isolated teams, where individuals begin to make decisions that should require cross domain knowledge, but instead move forward without that knowledge, and often wastes significant time when having to fix their mistakes. This amount of rework can also result in a crunch time later to try and catch up on the previous wasted effort.

One of the other important things that Keith mentions is the issue of burnout during a crunch, and estimates that only two to three weeks actually show any improved velocity. Once a month (or more) of crunch has been put into effect the overall velocity is actually worse than that of a non-crunch velocity! People will get tired, frustrated and upset with extended overtime, and Keith points to the that measures the quality of life of game developers across multiple industries, which is a good read I will probably comment more on in a later post.

The book also goes on to describe a number of key aspects regarding Agile practices (running a scrum, user stories, minimizing up front documentation, continuous integration and working builds every sprint) but also concepts for implementing and introducing Agile and scrum to the workplace, shifting emphasis to a team responsibilities for setting schedules and working with Agile for Art, QA and Producers.

Overall the book offered some valuable insights and interesting experiences. I would love try and implement more Agile processes at my current workplace, but we shall see how strong the culture is resistant to change. There are a number of jokes about trying to change culture like Angry Monkeys if you are not familiar with the story (the link points to RTP Scrolls which gives a good example). It is a shame really, since I do feel that Agile is the way to go for any game, and that all management styles eventually move closer to Agile anyway, since it allows the most flexibility and creative changes to make the game more fun. I guess it is like that saying, that the only thing harder than learning something new, is forgetting something old.

But when it all comes down to it, game development should be fun too…
Bye for now,

Thanks Clinton, I enjoyed the book and found it quite interesting. I have been attempting to inject some more modern practices from your book (and agile methodologies) into my current workplace, but they have a strong culture (largely stemming from 50+ years of warehouse & manufacturing procedures) so I think it will be a gradual, but positive change.
