(Mutatis mutandis is a Medieval Latin phrase that means "the necessary changes having been made")
It is often said that management and leadership are not for the faint-hearted. They are also not for the simple-minded. We learn from experience that no two employees are the same, no two clients are the same, and so on. To add to this complexity, we know that nothing stays the same; change is ever present. The employee changes. The business environment changes. We change.
This is not to say that what we learn today is of no use tomorrow. We realize that context is everything and we understand the need to adapt and adjust our approach every time we give feedback, negotiate, persuade. We can apply our knowledge and learning to new problems, mutatis mutandis, after we have made the necessary changes to what we know.
