According to Lean Frog your business needs to concentrate on purpose, process, and people.

Purpose: In order to successfully reach its goals, which customer issues will the company handle?

Process: How will the company evaluate all of its processes and ensure that every step is important, proficient, accessible, sufficient and flexible. But, be able to do it in a manner in which all of the steps flow together perfectly?

People: How will the company make sure that each process has someone who is accountable that can measure each value stream for its goals and streamlined operations? How can the company ensure that each person who comes into contact with a value stream will consistently do it in a manner that emphasizes maintenance and improvement?

According to Womack, all carpenters have to have an image of what they are going to produce before they can successfully use a hammer. In a similar manner, all lean thinkers must have an image of what needs to be done before they can use their resources. Womack also says that the best way to do this is to think very long and hard about purpose, process and people.
