1.2  Benefits of modelling


With ever-greater scrutiny on corporate and public sector organisations, decision makers can no longer afford to take a 'seat of the pants' approach. It is expected, and often required, that adequate analysis is performed to demonstrate that actions taken have been thoroughly evaluated and tested before committing stakeholders’ funds.
 
Specific benefits include:

- The ability to consider multiple options, assessing the impact
   of changes on key drivers, thereby identifying the key risk
   factors.

- The process of designing a model develops a clearer
   understanding of which variables are critical and their
   impact on likely outcomes.

- Limiting the costs of evaluating ideas prior to approval,
   reducing or avoiding trial-and-error costs.

- The scrutiny of logic and assumptions that accompany
   model design increases precision and enhances insight.
 
It is for these and many more reasons that almost every transaction or investment decision now rely heavily on some form of financial model or analysis.
