Lean will constantly be testing your abilities as a leader from the very beginning. You will find balancing the day-to-day operations of the company and incorporating Lean to be challenging at times. As the years pass, depending on your drive, it will become easier and a way of life. You want to make sure during hiring phases of the company to bring people on who have some level of Lean experience. Previous Lean training would be a minimum requirement.
It is equally important to consider looking at how to encourage and continually invest in current employees. Developing some type of incentive and solid internal training and progression programs is vital, not only for existing employees, but the newcomers too.
