How do you securely plan who, what, where, and when at the lowest level?
Where planning usually falls down is when you try to marry the planning outcomes to operational decision making. In a plan you make decisions at high levels that are generally thought to be accurate based on historical trends. It’s a best guess using all of the information available at hand, and short of having a bat-phone to Cleo the Psychic, it’s your best option. My problem isn’t with the concept, or whether you use a 2 year CAGR versus a 3-month rolling average, it’s with how the planning assumptions are applied and how execution flows as a result.
