Debugging is different to looking at the process and identifying how the bug even got there through the lifecycle of the module at hand. The article to me seemed to be talking about that rather than debugging a live issue. Debugging in local is exactly the same as measuring things as you work, I.e. The width of a bolt and what the error is. Incidentally, debugging in local should be replaced with unit tests so you can get a consistent automated check. Debugging is only really useful when you don&#x27;t really understand either an algorithm or set of frameworks. The equiv in eng is to just start throwing different components together and then executing them to measure what the effects are, which by the way I doubt would ever be done using materials destined for live.
