It depends on the project itself. For example, if you opened a restaurant and after six months there isn’t enough sale, then there is a problem that you have to solve, which could be the taste of the food, its type, location, price, service, etc.

In service companies, it may take five years, but the weak business always needs change and development, but it is not canceled unless in worst cases.

In other words, if the restaurant did not succeed even after changing the food, hiring a new chef or manager, or creating new services, try changing the name completely.
