forecast of demand

Needs forecasts of demand to plan sales strategies

I mean in simple or plain English:

If you need to plan sale strategies you must know the deman of the selling production in time

What is your question?

Both are correct?
First one is in the account book
Secont one I wonder whethr my understanding is correct

I would have written the first one as “Needs demand forecasts to plan sales strategies.”

This means that a person needs to have the predictions of customer demand before he can plan his sales strategy. He can’t do his work unless he has them.

I don’t understand about half of your second sentence.
