The one where we talk about TECHNICAL DEBT in Software Projects. What is Technical debt? It's "Technical debt is a concept in software development that reflects the implied cost of additional rework caused by choosing an easy solution now instead of using a better approach that would take longer. The term was first coined by Ward Cunningham, and it's often used to describe the trade-offs between short-term and long-term productivity" PS: Contrary to popular belief I can confirm that Dave Litten is probably not a Vampire that's been alive for centuries teaching Project Management. Probably.
