during alpha testing why customer people r invited?

Answer Posted / debashish_samanta

Alpha Testing is nothing but Acceptance testing.
So in Alpha testing the Client has to verify
The Product is developed according to their
1.Requirement and Specification.
2.SLA(Service Level Agreement) i.e
Time Line
3.DRE (Defect Rate Efficiency)<0.8
DRE = DRE=A/A+B = 0.8
A = Testing Team (Defects by testing team)
B = customer ( " " customer )
If DRE <=0.8 then good product otherwise not.

If client is missing any thing and they are giving a green
signal to the product then later on if they are getting any
error then the product has to come in a new cycle again.
