Your business plan will need to change from time to time. With that in mind, plan to review it on a regular basis with an eye towards whether there is any need for change.
Consider the hints that you already may be getting such as:
Technical issues: (signs or redundancy, overload, timeliness)
Complaints : (from customers or from staff)
Colleagues: (Discussions or events regarding current issues)
Ways to assess and review can include personal time outs, annual retreats or meetings or even brain storming sessions with peers or professionals from within.
