What is demand analysis? why it is important to do demand analysis, and?

Question

How does the demand analysis profit you and what factors are important to consider in demand analysis?

Answer 1

if you're talking about aggregate demand (national demand) then you are talking about GDP.

AD=GDP=C(consume)+I(investments)+G(gov... expenditure)+X(export-import)

analyzing these components of demand you are mainly analyzing whole economy on macro level.

If you consider demand on a micro economy level it is very obvious that you need to know your product/service is wanted and a lot of other stuff.
