What should we do (or not do) to be successful in this scenario?
Having worked your way through the other steps it should now be possible to establish an action plan in order to move forward. The action plan will be defined based on the test results, the internal ambitions of the organisation, as well as the strengths and weaknesses that have been identified.
Typically, your scenario planning activity fits neatly in the overlap between organisational strategy, environmental analysis (your PESTLE) and more definite elements of forecasting (such as planned student numbers or likely grant allocations), although there may be less obvious connection with these if using the technique for a more localised issue or project.
If you have undertaken scenario planning as a strategic tool, you can therefore use your resultant action plan as a mechanism to influence your operation towards achieving your strategy.
