deciding on a iteration tempo for your project Browse Trails 10 days Pri. 10 18 Chapter 1 List Equipment 7 days Pri. 10 These two features will take 17 working days to complete... that’s close to a calendar month, so we iterate when we’re done here. Your job was to build an iteration plan for Tom’s Trails. You should have come up with something like we did, below: We had to put a lower priority feature in place here, because our high priority feature depended on it. Log In 2 days Pri. 30 Buy Equipment 15 days Pri. 10 Search Trails 3 days Pri. 20 Around 20 working days per iteration Download at WoweBook.Com The last iteration was a short one, and that’s okay, too. Add a Review 2 days Pri. 20 View Reviews 3 days Pri. 20 Compare Trails 1 day Pri. 50 Your project ends with an iteration, where the customer gets to “sign off” on what you’ve built. This is probably the only plan that serves the customer’s priorities, keeps iterations at a manageable length, and gets the job done. If you came up with something different, take a hard look at why you made different choices than we did.
Q: The last feature scheduled for my iteration will push the time needed to way over a month. What should I do? A: Consider shifting that feature into the next iteration. Your features can be shuffled around within the boundaries of a 20-day iteration until you are confident that you can successfully build an iteration within the time allocated. Going longer runs the risk of getting off course. Q: Ordering things by customer priority is all fine and good, but what happens when I have features that need to be completed before other features? A: When a feature is dependent on another feature, try to group those features together, and make sure they are placed within the same iteration. You can do this even if it means doing a lower-priority feature before a high-priority one, if it makes the high-priority feature possible. I decided to have the customer check on the project after each feature. That’s even better than iterating every calendar month, right? Your iteration length should be at the right tempo for YOUR project great software development An iteration helps you stay on track, and so you might decide to have iterations that are shorter or longer than 30 days. Thirty days might seem like a long time, but factor in weekends, and that means you’re probably going to get 20 days of actual productive work per iteration. If you’re not sure, try 30 calendar days per iteration as a good starting point, and then you can tweak for your project as needed. The key here is to iterate often enough to catch youself when you’re deviating from the goal, but not so often that you’re spending all your time preparing for the end of an iteration. It takes time to show the customer what you’ve done and then make course corrections, so make sure to factor this work in when you are deciding how long your iterations should be. Download at WoweBook.Com This occurred in the previous exercise where the “Log In” feature was actually a low customer priority, but needed to be in place before the “Buy Equipment” feature could be implemented. Q: If I add more people to the project, couldn’t I do more in each of my iterations? A: Yes, but be very careful. Adding another person to a project doesn’t halve the time it takes to complete a feature. We’ll talk more about how to factor in the overhead of multiple people in Chapter 2, when we talk about velocity. Q: What happens when a change occurs and my plan needs to change? A: Change is unfortunately a constant in software development, and any process needs to handle it. Luckily, an iterative process has change baked right in...turn the page and see what we mean. you are here 4 19
