Why do Planners and Buyers order/produce less than they have sold last year?

Agreed with the answers to all colleagues

This is not a general rule 

  But if it happens 

In my opinion there are many reasons 

  Such as 

  * - bad planning 

* - Fluctuations in supply and demand 

* - Overstatement 

* - Shrinking market 

* - The constant evolution of  specially goods and electronic goods

When the last years' expectations are below met out,  and having excess stock with them so they are moving in a cautious way to comfortably improve the production/purchase order at a later date, delaying the decision until getting a perfect positive indication of the general trend and  company's marketing efficiency.

Hi Elke,

Thank you for your invitation.

1. The main reason is that over a period, the demand for the product drops therefore they order/produce less.
2. If new products are introduced, than they will be left with old stock and will have to sell at less prices

Thank you for your invitation and I apologize that you did not understand the question
