what was the demand how far it is successful​

Answer 1

Answer:

Ditch the Spreadsheet

Reading the suggestion above, you may have been thinking that you could calculate these values with a quick pen and paper or Excel session. While you probably could, you almost certainly shouldn’t. Why? Because effective demand capacity planning relies on a high degree of intra-operational visibility, which is almost impossible to achieve when you use programs like Excel whose files are often not centrally located or easily accessible for those who didn't create the file in the first place.
