When you look at the Shenzhen ecosystem in China, the biggest lesson might not be software-related, but rather logistical and methodological. It is a city where the time between an idea and a physical prototype can be extremely fast: an engineer can design a board in the morning, have it etched in the afternoon, and test it that very evening.
For a software developer, this approach resonates immediately with agile methodology.
Even before etching a circuit or assembling a mechanical chassis, code allows you to simulate the product's behavior.
In reality, the agile methods you already use daily in software development can be applied to hardware. This fluid combination of software and hardware then becomes an interesting tool to analyze your projects, fix them quickly in a short loop, and deliver concrete products.
