You may be tempted to do a maximum of things by yourself in your projects but there are always limits to what you can achieve. To increase production you need to improve your processes, but how?
|If you have a lot of work to do you can either hire lots of people to do it... or do more with your existing resources!|
Keep control of design and innovation as it's where most of the value lies. If you're doing something you're good at, and you should do, then you should be in charge.
However delegate production to make it cost effective and scalable. If you decide to do it all by yourself, then you'll be limited by your own abilities. Delegate and grow according to the needs and you'll improve greatly your production.
