My suggestion, have a look at the Business Model Canvas
It is starting at the Customer and not as many models in Strategy at the Mission statement, its set up is easy and is explaining the interaction of the different criteria.
Therefore good to have as one of your tools and as I presume of help in your question
By the way in my opninion the BBSC is good for Strategy, the EFQM as a next step for Excellence.
