If you have never worked in an industry, you should avoid taking on the responsibility of a troubled business. A turnaround story on an unprofitable business is excellent to tell but hard to write if you have never done it before.
A crucial key to business success is organization. Proper organization will help you complete tasks and stay on top of things to be done.
Before making any significant changes at a company you are taking over, take as much time as you need to understand how everything functions and who the key players are. Your genius changes to the process may have been attempted before with disastrous results, and just you being you may not be the secret to its new success in this attempt.
