A programme paid a premium for a GaN platform and then discovered that the enclosure had been sized for the higher frequency but not for the heat, so the design derated before it reached its rated output. The material had …
The most common specification error in this category is to state the wattage and assume the adjustable mode comes with it. The protocol support is an option, the range is a parameter, and the current limit is a third item. …
Two programmes adopted the extended power range in the same quarter. One shipped on schedule with a platform that was already characterised for the higher voltage; the other discovered that the cable, the connector and the thermal path all had …
Two chargers describe the same headline power and only one supports the adjustable range a phone uses to charge quickly. The two differ in the control loop, the firmware and the test plan, and the difference is invisible on a …
The cheapest way to protect a launch date is usually the one that costs nothing at the time: booking the slot earlier. The most expensive is the one taken in the final two weeks, when air freight and overtime are …
A brand placed its peak order in the same week as every other brand, and the goods arrived after the season had started. Nothing had gone wrong with the product or the factory: the order had joined the queue at …
A production schedule can be checked in four questions, and a schedule that answers all four is short. A schedule that answers none of them contains the same durations as the one beside it and no dates, which is why …
Two pilots ran in the same week on similar platforms. One produced a fixture change, a revised test limit and a verified packing process; the other produced photographs of some units and a request to proceed. Both were called pilots, …
Mass production rarely fails at the assembly step. It fails at the interface between the pilot and the line: the fixture that existed in one copy, the component lot that changed after the pilot, the test limit carried over from …
Two programmes ordered the same mould in the same month and received their first shots five weeks apart. The design was similar, the tool shop was the same and the price was close. The difference was when each programme had …
A brand waited three weeks for a sample that proved the design and nothing about the process, then lost two more weeks on the branded sample it actually needed for approval. The samples had been requested in the wrong order, …
Production planning is a cycle of five steps rather than a single schedule, and the two steps most programmes skip are the ones that protect the date: checking the plan against capacity, and routing every change through one channel. A …
