A Technology Business Review should be a staple of all IT companies. A TBR just doesn’t review aging hardware for example but rather a review of your business as a whole. Perhaps your remote workplace needs fine tuning or your planning for a business expansion and need technical guidance.
Another benefit of a IT company TBR is putting time and effort into preventing tech fires. This could cover a few areas such as really old workstations, an aging server or even a cumbersome workflow process that consumes a lot of time. Security is very important and security recommendations can be made in a TBR as well.
In the end the bottom line benefit is you stay focused on your business and not reacting to tech problems.
