Why Performance…?Does the application respond quickly enough
for the intended users?Will the application handle the expected user
load and beyond?Will the application handle the number of
transactions required by the business?Is the application stable under expected and
unexpected user loads?Are you sure that users will have a positive
experience on go-live day?
