Remembering all the models

I’m not sure what you mean by a basic knowledge compared to a thorough knowledge.

You are rarely required to explain models, but you are expected to be able to apply them to scenarios, so concentrate on being able to do that.

A model is important if it comes up! Some ‘models’ are little more than lists – but still useful. My top dozen would be:

1 PESTEL
2 5 Forces
3 Generic strategies
4 Ms model for resources
5 Ansoff’s matrix
6 Strategy evaluation: suitability, acceptability, feasibility
7 Boston consulting group
8 6Is of e-business
9 Harmon’s process strategy matrix
10 4 or 7 Ps for marketing
11 Project initiation document contents and project gateways
12 Job design and motivation

Feel free to include particular favourites.
