The CFO'S Perspective

For those not familiar with the term, a decision tree is a flow chart that works through all possible response options in a scenario to analyze resulting outcomes. Basically, it is a visual version of an “if this then that” statement across all possible alternatives.

The “branches” off each decision alternative that result use data analysis to forecast the most likely outcome of each decision. When one decision leads to another decision that must be made, that branch splits to continue extrapolating the effects of each subsequent decision. The result is a tree-like diagram (hence the name) that is easy to understand and interpret.

Decision trees can be more conceptual in nature or have numbers to back up decision scenarios, as is the case of pricing changes affecting revenue figures. For decision trees with complicated calculations, a software program can assign values and probabilities to streamline decision-making. A decision tree is a critical part of strategic planning because it allows decision makers to analyze the effects of a significant change throughout different areas of the business.

Budgeting and strategic forecasting creates a business roadmap to maintain stability and achieve growth. However, for forecasting to be accurate it needs to be modified when significant changes occur either internally or externally. This is especially important to consider this year, as supply chain disruptions and changing business regulations have drastically changed corporate outlooks across the country.

If you understand now that there is a high likelihood of needing to undergo reforecasting next year, you will be better equipped to do so when the time comes. Kory Wagner explains, “Expecting your assumptions to last through an entire year is at best naïve and at worst detrimental to your business. Incorporating reforecasting into your regular budget process, as needed, will keep you on track and help you roll with the punches.”

Some companies are reforecasting-averse, so they shorten their budgeting cycles from annual or semi-annual to quarterly or monthly to reduce their chances of needing to do so. But if 2020 has taught us anything it is that every company should be prepared to reforecast as needed because it could become a necessity at any time.

So, this year as you finalize budgets and forecasts, take the approach of “planning to re-plan.”
