15. QA/QC Concepts
• Quality Assurance
Quality Assurance (or QA) covers all activities from
design, development, production, installation,
servicing and documentation.

16. QA/QC Concepts
• Quality Control
Quality control refers to the process,
– most often implemented in manufacturing,
– monitoring the quality of finished products through
statistical measures and
– an overall corporate commitment to producing
defect-free products.

17. QA/QC Concepts
• Organizational Level.
At the organizational level, QA activities ensure
that the program or organization is successful by
overseeing the system implementation necessary
for individual projects in the program, and making
sure activities have the resources they need to be
successful.

18. • Project Level (Design, Estimate and Initiation)
At the project level, QA activities support the success
of an individual project by ensuring that accurate
information is channeled to the right people at the
right time so that decisions can be made during
project implementation.
QA/QC Concepts

19. QA/QC Concepts
• Technical Level.
At the technical level, QA activities ensure that the
individual technical activities that generate,
process, or synthesize data (or other information)
for the decision process are performing within
accepted limits.

21. Roles of QA/QC Department
1. Verify that requirements are followed,
2. Verify that controlling and checking an activity have been
done,
3. Ensure that approved working methods are established,
4. Evaluate the reported principal causes of non-conformances;
5. Evaluate the effectiveness of corrective action, and
6. Determine where improvements are required

22. Quality Control
Role of Quality Controller includes:
1. monitoring,
2. Inspection,
3. reduction of variation,
4. elimination of known causes, and
22

23. Quality Assurance Quality Control
A systematic set of activities to
provide confidence that
requirements are established
The process by which quality is
compared with applicable
standards;
An activity that establishes and
evaluates the processes
An activity which verifies if the
product meets pre-defined
standards.
Helps establish processes. Implements the process.

24. Quality Assurance Quality Control
Sets up measurements
programs to evaluate
processes.
Verifies if specific attribute(s) are
in a specific product or service
specific product or service
Identifies weaknesses in
processes and improves
them.
Identifies defects for the primary
purpose of correcting the
defects.
Prevents the introduction of
issues or defects
Detects, reports and corrects
defects
Difference in responsibilities

25. Difference in responsibilities
Quality Assurance Quality Control
Evaluates whether quality
control is working for the
purpose of determining
weakness in the process.
Evaluates if the application is
working for the purpose of
determining defect in the
functionalities.
Improves the process that is
applied to multiple products.
Improves the development of a
specific product or service.
QA personnel should not
perform quality control unless
doing it to validate quality
control is working.
QC personnel may perform
quality assurance tasks if and
when required.

Quality Management Objectives
zero defect (no defects on project
hand-over)
identify and solve problems before
customer does
establish true quality control by
making quality “built in” and not
“inspected in”.

34. Why do we do this?
• For better efficiency,
• Fewer rejects,
• Reduce if not eliminate customer complaints,
• Improve customer relation
• Improve supplier relation.
• And to answer our slogan:
– Open Challenge Quick Response

Preventing mistakes is much more
time and cost-effective than correcting
them.
