Design Testing
Overview
User and system designer work as partners to develop
not only an efficient application system, but also one
that is acceptable to the user.
Objective
Test process recommends scoring the design success
factor, conducting a design review; and inspecting
design deliverables

Input
The sooner the project team become aware of
potential defects, the cheaper it is to correct
those defects
When defects are found, the corrective process
can be so time-consuming and painful that it
may appear cheaper to live with the defects
than to correct them

Task 1: Score Success Factors
Scoring is a predictive tool that utilizes previous systemsexperience.
Existing systems are analyzed to determine the attributes
of those systems and their correlation to the success orfailure of that particular application.
When attributes that correlate to success or failure canbe identified, they can be used to predict the behavior ofsystems under development.
The more heavily the user is involved, the higher theprobability that system will be successful

Task 4: Inspect Design Deliverables
Inspection is a process by which completed butuntested design products are evaluated as towhether the specified changes were installed
correctly 3 types of defects
Errors, the change has not been made correctly
Missing, something that should have been changed ,but
was not changed
Extra, something not intended was changed or added

Output
Deficiencies uncovered in the design review
Defects and assessment produced by theinspection process
Results from deliverables inspection
No defects found
Minor work required
Major rework required
Training & product quality - enhance benefits of formalinspection
