The most important point is to make things as simple as possible first, and then think to improve the process.
I have no doubt that if you do not have good standardized work, you will certainly have many quality problems in your process. If you do have standardized work, be certain that it is being followed correctly; use the experience of the "king" to help create good standardized work procedures.
Just to finish, I want to make it clear to you that for the implementation to have passion, you must perform the implementation of each technique with joy, not simply implement because you must. Remember that Lean is for the organization; once it is well-implemented, it does not fall back. The implementation of Lean may be lost only when the system depends on a person.We must acknowledge that the system cannot rely on a single person; the system depends on all employees every day, hour by hour, minute by minute. When I left Toyota, nothing was lost with my absence, do you know why? The system was all standardized. It does not depend on a person; it depends on the operators wanting to perform their tasks according to the standards.
