The secret to making people buy your product
There is no greater waste than building something extremely efficient, well architectured (is that a word?), with high quality that nobody wants.
Yet we see it all the time. We have the Agile manifesto and Scrum probably to thank for that (the seeing bit.) “Our highest priority is to satisfy the customer through early and continuous delivery of valuable software”. It’s the valuable bit that is embodied by the Product Owner in Scrum, or “the value maximiser”.
Lean Startup has taught us that we suffer from cognitive bias and simply assume we know what customers want, and therefor should treat our requirements as assumptions. Get out of the building and ask our customers! We all know that Henry Ford would disagree. But could both be right.
