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.
As importantly, it also identifies road blocks - in advance. Your business plan should provide a common vision supported by tactical initiatives that, ultimately, creates greater value for your company. It may seem daunting, but by knowing your vision and its corresponding financial targets, you will have a better chance at executing how to get there and avoiding traps in advance.
