1. Managing Software Quality in an
Organization
By Mr. Fazal Wahab

2. Quality Management System
• QMS is used to describe a process, which ensures
and demonstrates the quality of the products and
services provided by the organization.
• QMS is a set of procedures/processes, which as a
whole form the basis for executing organization’s
product/service delivery mechanisms.
• QMS begins with a Vision and Mission Statement of
the organization committing itself to quality.

4. Quality Management System
• Requirements for QMS as per ISO 9001-2000:
– Needs to demonstrate its ability to consistently
provide the product that meets customer and
applicable regulatory requirements, and
– Aims to enhance customer satisfaction through
the effective application of the system, including
processes for continual improvement of the
system and the assurance of conformity to
customer and applicable regulatory requirements.

5. Quality Management System
• QMS emphasizes the need for the quality process to
be actively managed to ensure that it continues to
be effective and efficient.
• Software Development organizations must keep
constant review of practices and tools they use.
• Employees are equally important as practices and
tools.
• Employees to be properly trained in usage of QMS.

6. Quality Management System
• Training plays a very important role in quality
related activities of an organization.
• The QMS must ensure that the employees
have the right skills to do their jobs in a
professional way.
• QMS must also ensure that employees
understand their responsibilities.
• Successful QMS gives great emphasis to early
corrective action.

7. Quality Management System
• Successful QMS include ways to analyze records and errors
to determine their causes and make action plans to prevent
errors by eliminating their causes (Root Cause Analysis)
• QMS should be auditable. This means that
– The development process must be well documented and
– Quality records including measurements must be generated
throughout the software development process.
– Quality records:
• Review record of Project Plan
• Code review results
• Test execution report

8. Quality Management System
• ISO 9000:2000 requires that organization shall:
– Identify the processes needed for the QMS and its application
throughout the organization.
– Determine the sequence and interaction of these processes.
– Determine criteria and methods needed to ensure that both the
operation and control of these processes are effective.
– Ensure the availability of resources and information necessary to
support the operation and monitoring of these processes.
– Monitor, measure and analyze these processes, and
– Implement actions necessary to achieve planned results and
continual improvement of these processes.

9. Process Standardization
• Needs for process standardization:
– Process standardization helps to reduce the problems of
training, review, and tool support.
– With standard processes/procedures and methods, each
project’s experiences can contribute to overall process
improvement.
– Process standards and definitions provide the basis for
process and quality measurement.
– Process definition takes time and effort to produce, it is
impractical to produce new ones for each software
development project.

10. Summary of QMS
• A QMS is a set of procedures.
• Procedures are at the heart of the QMS.
• Procedures are the documents which tell staff
how to follow a quality system, day to day, in
their work.
• The QMS is the complete work process,
including policies, procedures, tools and
resources, both human and technological.
