What does "Group projections" on the demand graph include?

"Group projections" on the demand graph include both definite and tentative revenue planning. This approach allows for a more comprehensive understanding of expected demand by factoring in both confirmed bookings, which provide certainty for revenue, and tentative bookings, which reflect potential future business but are not yet confirmed.

In the context of demand forecasting, recognizing tentative bookings is crucial since it helps in projecting overall revenue more accurately. This can be important for planning resources, managing inventory, and making strategic decisions about pricing and promotions. By including both types of bookings, organizations can better assess future performance and make informed operational choices.

The other options do not capture the full scope of what "Group projections" entails. Therefore, the correct answer encompasses the broader range of planning that includes both confirmed and potential future revenue.
