If someone is a computer engineer and his expertise is machine vision or voice recognition or totally machine learning fields. But we know a robot has electrical parts and mechanical parts as well. Also it's possible to consider we like to create an application on Web/Windows/Mac/Android/ios for our robot too! And many other possible extra conditions.
So our founder is a great man in ML field but not in web/mobile/electronics/mechanics and other fields of engineering that may needed for the company. Then How should he manage people with other expertises and evaluate if they are best(I mean very well) people to choose and hire them? Do they their jobs well?(I mean there is no better/easier/less expensive ways to do that job?). And when one o them stuck in his/her job and couldn't find the solution, how can he help him/her to done the job?
