One of the problems about using terms such as ‘budgeting’ and ‘forecasting’, is that there is no generally accepted definition of what they mean. Budgeting is often referred to an annual exercise where the organisation’s resources gets spread among the departments, while forecasting is about predicting the future.
In recent times, forecasting is seen by some as a replacement for budgeting, and the mechanism through which continuous planning can be achieved. Given my understanding of ‘budgeting’ and ‘forecasting’ I would have to disagree – but it may be that I have misunderstood what is implied by these terms.
This makes it very confusing for organisations wanting to adopt a ‘best practice’ approach as they too may misunderstand what is meant. For example, making a statement such as ‘replace your outdated budgeting process with rolling forecasts’ could imply that budgeting is bad while forecasting is all you need. Which could be both right and wrong depending on how your understand what is meant by each.
Now I’ve got you totally confused, let me explain how I sees the difference between planning, budgeting and forecasting.
