Technical Debt - #phpbnl16

Technical debt is, in a way, just like financial debt. We'll take a look at how it influences, even stifles, every aspect of our work, from the decision which features we develop, to extra planning efforts, to the actual development of new features taking extra time – and we'll see how to get rid of technical debt in the long run.
