Why not to be afraid of asking customers to pay for technical dept¶
An alternative name for this post could be: I definitely have to learn to take less, or to be happy with less perfectly work. As I had to finish a new feature for one of our customers today, while being at the TYPO3 conference in Amsterdam, I took a look at the time tracking. This feature took five hours of time to be implemented. Everything he requested was to implemented a Newsletter registration with double opt in for a lottery game. Of course the customer already has a registration with double opt in for the newsletter. So the only task I had to do, was to bring the information from lottery form to the newsletter. Sounds like a small deal and it actually was. But where does the time come from?
Perhaps you already guessed, it’s technical dept. The existing registration system wasn’t designed to get new subscribers from something else then the own web form. Also the validation of neither the newsletter nor lottery web form did work as I expected. Not all necessary inputs were validated as required. The output of error messages was not styled. And if you didn’t insert a valid email address to the newsletter subscription, all you get was a blank page.
If you’re like me, that’s definitely not what you expect. You want to have a form with all validation rules, nice styled error messages. This way everything afterwards can rely on the input.
As I’m currently testing manually I’ve checked first my own implementation. As it worked, I tried the old implementation, whether I broke anything. And all the mentioned issue occurred. So of course I thought I broke everything. I checked it twice, checked the current version on live system and it turns out, that’s the current implementation.
So that’s the first point where the technical debts occurred and procured extra time, which leads to extra money someone has to spend.
But there is a second technical dept. I could not implement the transfer from one existing form to the newsletter system as clean as I would. So it just works out for this one situation and was no general solution. But as there was no more time, the customer called us very late, I need to make a decision. If the existing system was well designed, I could spend the extra time to implement my solution the same way. But as there were broken windows (check out “Don’t Live with Broken Windows” by pragprog.com), I didn’t have either the time, nor the motivation, blame on me. So we run into the circle where technical dept creates even more technical dept.
So what’s the conclusion?¶
I don’t want to blame anyone, there are many reasons why you can get technical debts. But all you can do is to try hard and make your work as good as you can. As soon as you encounter technical debts, or broken windows, tell your boss, mate or customer. It’s not all about you, you are in charge to spread the work, and all together can find a solution. Does the customer want to pay the extra costs in the future? Does your mate care about the code base he has to work with too? How can you reduce the technical debts and repair the broken windows?
But sometimes, perhaps the windows are not even broken. Perhaps you are looking through broken glasses? In other words, perhaps you’re the only one seeing the broken windows, perhaps it’s a problem for you, but no one else. If the customer is happy and everything works as he expects, it’s totally fine. For now ... Of course if you have higher claims that’s good, because you have a reason to keep going and improve. But always check reality and your personal opinion. What’s most important for now? What cares more at the moment?
Working software over comprehensive documentation
It doesn’t help if you implement the 110% solution, but can’t finish soon enough and the customer get into some trouble.
Of course, as everything else, it’s just my very own, personal opinion. So as with anything else you read somewhere, check what fit for you.
