None of companies is perfect, nor can it be.
In every company there is a good operation, there is a bad operation.
As a manager, it is our duty to protect and disseminate the good ones, correct the bad ones, and slowly bring the ones that are not into the corporate culture for easy digestion.
Below is a slightly rough version of the plan that I created while working as a general manager at a place, and kept to myself, keeping track of progress and updating it from time to time.
Of course, when the plan was mentioned, there was a timing schedule, goals, progress and responsibilities, and the plan was in a tabular form, but I took them out to publish here. I also removed some social and hierarchical issues and company specific issues that would reveal the company. In addition, some issues take place in two separate places. (I did that, no mistake)
