So I chose a vending business for an assignment (essay) and it's an innovative pizza vending machine which contemporary management technique should I choose for this business? The name of the business is PizzaForno. There are at least 13 techniques that I can choose from like benchmarking, the value chain, activity based costing and management, business analytics, target costing, life-cycle costing, total quality management,business process improvement (These are just a few out of the 13). I am having trouble choosing the right technique for this business as this is the main idea for the paper. 

Which technique should I choose for this company?
