Project management has a defacto method in PRINCEII. The method uses 7 Principles, 7 Themes and 7 Processes in a system designed to place any project under control.
General Management, to my knowledge, do not possess such a widely used methodology. It will enable managers to be guided within a framework. Best practice is also a consideration.
In my experience, most entrants in management, junior managers and even seniors managers, would welcome a standard way of dealing with the management issues. I will aim to communicate parts of a methodology that I’ve used as a consultant and that enables organizations to increase their performance.
