A list of 20 blunders to avoid in strategic planning-

Provide a list of no less than 20 blunders to avoid in strategic planning formatted as simple sentences and /or phrases

This is not an internet research project;

The list should not be restricted to business functional area implementation project, such as IT projects etc. Nor it should be limited in perspective. It should be as comprehensive and inclusive as possible.

Let me add the following clarification: This list is strategic and not tactical, operational or a philosophical exercise. What this list should not be?

Not an IT implementation list,

Not a marketing list,

Not a sales or customer care list

Not an HR or human capital development wish list

Not a story teller about coworkers' relationships

Not a collection of general philosophical ideas

It should reflect the elements of the strategic planning process, if it does not, it will not be credited.
