Business by nature is competitive, and few businesses are completely new. If there are no competitors, be careful; there may be no market for your products. Expand your concept of competition. If you plan to open the first roller skating rink in town, your competition will include movie theaters, malls, bowling alleys, etc.
If you have not already, setting up a capital committee to review expenditures in advance of the start of the project provides some assurance that the projects have been vetted against return on investment. Lastly, developing a post-audit process enables the team to review and monitor the progress of ongoing investments.
