Defining Scope of the Decision Problem

It is important to understand which questions are going to be addressed in the analysis - to define the scope of the decision problem at hand.  Without explicit bounds it is easy to make the analysis unreasonably complicated.  Blindly plunging into analysis may also result in a lot of effort and money wasted on working on the wrong problem.

The analysis begins with structuring or framing of the decision problem.  The purpose of the decision frame is to specify what is under consideration and what is not.  All possible decisions can divided into three categories: policy, strategy and tacticsDecision Hierarchy can be very useful for illustrating these three levels.
 

Decision Hierarchy
 
 
Policy level consists of questions that will be treated as given and fixed during the analysis. In this case such questions as the need for expansion, feasibility of continuing the production or even staying in business are very important questions, but would make the analysis too long and complicated.  So, we will assume for the rest of the analysis that these issues have been decided on.

Strategy level consists of questions that the analysis will concentrate on. The main question raised by the Board of Directors is "What expansion plan should we go for?" The two main considerations here are the additional capacity that the company will have and the amount of money the company will have to spend.

Tactics level consists of the decisions that will be made later, after a specific strategy is chosen. All the operational and financial planning will be done according to the strategy chosen and the infrastructure and technology decisions will have to be made when the facilities are ready.
