Timeline

The timeline is not critical to a hobbyist project, but if you are developing custom hardware for a company or your own start-up, it is the most important part. For a simple hobbyist board, such as the model rocket example, one week from concept to a completed layout is plausible, but for cheapness manufacturing can take up to 2 weeks! If you are spending more money, boards can be completed as quickly as one day turns.
Picture
The hobbyist board only takes one week to design all the hardware! Unfortunately, to keep costs low, the board manufacturing can take up to two weeks. When the board arrives two weeks later, the soldering and firmware should only take one or two days along with testing of the project!

The shorter company timeline spends two weeks on schematic design and layout with two day manufacturing to finish the board in just three weeks. Of course this timeline could be shortened by using multiple people and really depends on the size and complexity of the PCB.
things are about to get real!
