the customer still rules And it’s STILL about the customer Let’s say you’ve calculated your new velocity. You collected bugs and put them all in a bug tracker. You waded through all the piles of unfinished and delayed tasks and stories, and had the customer reprioritize those along with stories planned for the next iteration. You’ve got your board ready to go. You still have to go back and get your customer’s approval on your overall plan. And that’s when things can go really wrong... 360 Chapter 10 All your estimates from planning poker, your stories, your nice organized big board...they all have to get trashed (well, not the board itself) if the customer makes a big change. This looks great, but I’ve got big news...We’ve just bought Mercury Meals, the galaxy’s premiere inspace catering company, and we need to integrate their ordering system into our code ASAP! Throw out everything else; this is top priority now. Download at WoweBook.Com You’ve suddenly got a ton of new code that you know nothing about, and it replaces a lot of what you had planned for the next iteration.
Now hang on a second! That’s a LOT of work to just toss out. Couldn’t we have checked with the customer earlier? Or done something else to avoid all this wasted time? Software is still about CHANGE Sometimes the customer is going to come up with a big change at the last minute. Or your best plans break down when your star programmer takes a new job. Or the company you’re working for lays off an entire department... But even though what you’re working on has changed, the mechanics of planning haven’t. You have a new velocity, and you know how many days of work your team has available. So you simply need to build new user stories, reprioritize, and replan. You already know how to... Calculate your team’s velocity Estimate your team’s user stories and tasks Calculate your iteration size in days of work that your team can handle You’ve got a ton of new code that you’ve never seen or used before. What would be the first thing you do to try and estimate the time it will take to integrate that code into the Orion’s system? Download at WoweBook.Com the next iteration you are here 4 361
