I think it's the same with everything like agile software development etc. There are some ideas with some good parts, but the way people end up applying them can cause a lot of problems. People should understand the domain, do risk analysis, change management etc. For example car companies are suffering from chip shortages. Maybe they should have stockpiled more? But on the other hand, the "parts bin" is the worst obstacle preventing innovation and integration in established manufacturers. Why do new companies like Tesla have way less electronic parts while legacy manufacturers have lots of separate boxes and wiring, all reducing reliability, increasing cost, space and mass. Because for a legacy manufacturer it makes more sense to use the same parts from the "parts bin" as for their previous model - it's just cheaper and faster, the supply chain already exists. https://www.youtube.com/watch?v=ZRkm6-bBk4U https://www.youtube.com/watch?v=ZRkm6-bBk4U
