The Essence of Problem Solving #5 — Reject Pseudo-So...

> TL;DR: Engineers "fight fires" and celebrate apparent fixes — until the same problem resurfaces with a bigger chain reaction. That is the "whack-a-mole" pseudo-solution: masking symptoms without severing the causal chain. The real fix is depth and breadth — distinguishing the surface cause (a blown fuse) from the essential cause (unconsidered worst-case operating conditions) — and frontloading the work: investing more up front in analysis and mechanism study, using methods like DRBFM, so the problem is solved completely the first time and never recurs. Beware the "Whack-a-Mole" Pseudo-Solution In product development, when a technical bottleneck appears, the engineer's instinct is to "fight the fire" — to find a solution by any means. However, if that search lacks focus and depth, it easily falls into the trap of a "pseudo-solution." Many of us have experienced this: a technical problem is discovered, a (seemingly) viable solution is quickly found, an engineering change is executed, test results look great, and the whole team celebrates the conquered challenge. But the good times do not last. Some time later, the same problem resurfaces — sometimes triggering an even larger chain reaction. Only then do we realize: the original solution never touched the root; it...
