This is my issue - I don't know. I assume any time is worth wasting if your developer builds even a small business since the value of anything over 5 employees is likely more than a million. Time management is not my concern at all. If I could legally start a business I would begin working on it tomorrow

My current strategy is to open source everything because there's no reasonable way my company can take ownership of something that's free. I can't develop anything for money even though I've been asked to consult many times for many people.
