Retool your Sales and Marketing Process with Lean: The tendency is to jump into EDCA (Lean Startup) and try to create a silver bullet. When “retooling”, you should delay starting “new” marketing ideas. You start with CAP-Do and categorize and develop the idea and practice of standard work. Standard Work consists of understanding the basic Lean principles, an understanding of your value proposition, how your product/services are used and the markets you serve.
