Each business is a system of mutually influencing elements: departments, people, processes, etc. In every system, there is a key constraint — a weak point in the company’s process, which defines the revenue and the growth more than others by its limits. The magic of the key constraint is that when the company overcomes it, it creates the maximum impact on the whole system: the company reaches new numbers in metrics, faster gets target revenue, the growth dynamic accelerates. After we overcome it, the constraint moves to another part of the business and we repeat the cycle, launching the process of constant improvements and growth. The goal of the growth coach is to help the team to identify the current key constraint, to find the right hypothesis to overcome it, to use the right tool and methodology, and to create a system of self-diagnostic and constant improvements, while helping the team to keep the focus on the goal.
