When you cut corners, you pay for it later. Time not spent discussing the requirements in detail leads to misunderstandings; if you don’t spot it later on, you might have to wait until the show and tell for the customer to spot it – now you’ve wasted loads of time. Time not spent thinking about the design can lead to you going down an architectural blind alley that causes loads of rework. Finally time not spent refactoring leaves you with a pile of crap that will be harder to change when you start work on the next story, or even have to make changes for this one. Of course, you couldn’t have seen these problems coming – you did your best, these things crop up in software don’t they?

But what if you hadn’t rushed? What if rather than diving in, you’d spent another 15 minutes discussing the requirements in detail with the customer? You might have realised earlier that you had it all wrong and completely misunderstood what she wanted. What if you spent 30 minutes round a whiteboard with a colleague discussing the design? Maybe he would have pointed out the flaws in your ideas before you started coding. Finally, what if you’d spent a bit more time refactoring? That spaghetti mess you’re going to swear about next week and spend days trying to unravel will still be fresh in your mind and easier to untangle. For the sake of an hour’s work you could save yourself days.
