esults from an iteration Your iteration is just about complete... You’ve made it! You’ve successfully put your process in place: the stories have piled up in the Completed section of your board, and everyone’s ready for a little breather. Before people head out for the weekend, though, let’s do a quick status check: With testdriven development and automated testing, your code works... and you’ll always know if it stops working. 318 Chapter 9 What we’ve got Customer-driven functionality Compiling code Monitored builds Continuously tested code Solid test coverage Reliable progress tracking Pacing that adapts to the team The burn-down graph and velocity turn idealistic schedules into real, quantifiable dates and deliverables. That’s an impressive list—but don’t turn the lights out in the office just yet. Suppose all your hard work has resulted in a day or two to spare at the end of your iteration. What else could you do if you had more time? Skeptical you could have time left? A good velocity calculation, staying on task, and accurate estimates will get you there faster than you think. Download at WoweBook.Com User stories and frequent customer interaction ensure your software does what the customer wants it to do. You know if someone tries to check in code that won’t build—and because of continuous integration, you know your code is always buildable.
...but there’s lots left you could do There are always more things you can do on a project. One benefit of iterative development is that you get a chance to step back and think about what you’ve just built every month or so. But lots of the time, you’ll end up wishing you’d done a few things differently. Or, maybe you’ll think of a few things you wish you could still do... You’ve worked hard putting this process together, but the whole point of iterative development is to learn from each iteration... how can you improve your processes on the next iteration? Everyone documented their code, right? No typos, misspelliins, or incomplete ? Sometimes a design pattern doesn’t really show itself until you’ve implemented something more than once. Maybe you didn’t need a factory in the first iteration... or the second. But by the time you add more code in the third iteration, things are screaming for a helpful pattern. What we don’t have Process improvements System testing Refactoring of code using lessons you’ve learned Code cleanup and documentation updates More design patterns? Development environment updates R&D on a new technology you’re considering Personal development time to let people explore new tools or read You may be cutting-edge now, but when do you have time to learn about even newer technologies and work them into your projects? Which of these things would you feel like you have to do? Which ones do you think you should do? Are there things that can be put off indefinitely? Are there other things you’d like to do that are not on this list? Download at WoweBook.Com ending an iteration You’ve got unit tests, but users haven’t tried the system out yet. And users always find things the best testers miss... No matter how slick your design seemed early on, you’ll always come up with just a little something that will make it so much sweeter. Do you do that now? There’s always some new tool out there that will “revolutionize” your build environment—or maybe you just need to reorganize dependencies. Either way, when do you update your environment? you are here 4 319
