Why we stopped breaking down stories into tasks An Article by Adam Silver adamsilver.io The Scrum process says to break down stories into tasks to make estimation easier, encourage collaboration and to be able to show more granular progress during a sprint. But after a few sprints, we decided to do the next sprint without creating tasks. As a result we drastically increased our velocity and never went back. Here I'll jot down some of the reasons we decided to do this: Breaking down stories into tasks is time consuming The tasks we came up with invariably would change as we worked on the stories Tasks are repetitive Tasks were often carried out in parallel Our estimates didn't improve It decluttered our task board It encouraged collaboration throughout the sprint While we started our process by following Scrum to the letter, we soon realised that breaking down stories into tasks was something that wasn’t worthwhile for us. In the end we realised that it was overplanning and poor use of our time. In the end we used that time to get on with the work and deliver at a significantly faster pace.

Wang tiles Wang tiles (Hao Wang, 1961) are a class of formal systems. They are modelled visually by square tiles with a color on each side. A set of such tiles is selected, and copies of the tiles are arranged side by side with matching colors, without rotating or reflecting them. The basic question about a set of Wang tiles is whether it can tile the plane or not, i.e., whether an entire infinite plane can be filled this way. The next question is whether this can be done in a periodic pattern. In 1966, Wang's student Robert Berger solved the problem in the negative. He proved that no algorithm for the problem can exist, by showing how to translate any Turing machine into a set of Wang tiles that tiles the plane if and only if the Turing machine does not halt. The undecidability of the halting problem then implies the undecidability of Wang's tiling problem.
