Evaluate historical data and prepare assumptions that will drive the planning process.

When it comes to evaluating historical data and making assumptions that will drive the planning process, there are several factors to consider. First, past trends should be examined in order to get a better understanding of where the company has been and where it is headed. This includes analyzing sales figures, expenses, market conditions and other elements related to the organization’s performance over time.

Next, any external influences such as industry regulations or economic changes must also be taken into account when preparing assumptions as they can have a big impact on how things may develop going forward. Finally, it is important to establish realistic expectations based on all available information so that any projections made are attainable yet still provide enough of a challenge in order for the team to grow and excel over time.
