Quality Management
Project Quality Management includes the processes and activities of the
performing organization that determine quality policies, objectives and
responsibilities so that the project will satisfy the needs for which it was
undertaken. procedures and processes of quality planning, quality
assurance and quality control, with continuous process improvement
activities conducted throughout, as appropriate.

Key Activities of Quality Management
• Plan Quality: The process of identifying quality requirements and/or quality standards for the project and product, and documenting how the project will demonstrate compliance.
• Perform Quality Assurance: The process of auditing the quality requirements and results from quality control measurements to ensure appropriate quality standards and operational definition are used.
• Perform Quality Control: The process of monitoring and recording results of executing the quality activities to asses performance and recommend necessary changes.

Plan Quality > Inputs
• Enterprise Environmental Factors
•Governmental agencies rules, standards and guidelines
specific to the application area, may affect the project
• Organizational Process Assets
•Organizational quality policies, regulations and guidelines
•Historical databases
•Lessons learned from previous project specific to the
application area, may affect the project

Plan Quality > Tools and Techniques
• Cost-benefit Analysis
– Consider the trade-offs of the cost of quality
• Constant focus on stakeholder satisfaction
• Constant focus on the bottom line (benefits must outweigh the costs)
• Cheaper and more efficient to prevent defects than have to spend time
and money fixing them later
– Benefits of meeting quality requirements are
• Stakeholder satisfaction is increased
• Costs are lower
• Productivity is higher
• There is less rework9
www.wizardea.com | [email protected]
Plan Quality > Tools and Techniques
• Cost of Quality
– Total cost of all efforts to achieve product/service quality
– Measures all work to ensure conformance to requirements and all
work resulting from nonconformance to requirements
– 3 types of costs
• Prevention costs
• Appraisal cost
• Failure cost
– Internal
– External

Plan Quality > Tools and Techniques
• Benchmarking
• Comparing similar activities to the current activities
• Current activities become a standard to measure performance
against (benchmark)
• Design of Experiments
• An analytical technique that identifies the elements or variables
that will have the greatest or optimal effect on overall project
outcomes
• A statistical method11
www.wizardea.com | [email protected]
Plan Quality > Outputs
• Quality Management Plan
• Quality management plan is a component or subsidiary plan of the
project management plan
• Describes how the project management team will enforce the Quality
Policy
• Documents the resources required to carry out the plan, the
responsibilities of the project team in quality implementation and all
processes and procedures that are used to satisfy quality
requirements
• Must address quality control, quality assurance and continuous
process improvement for the project
• Quality actions will be assigned to activities in the WBS12

Perform Quality Assurance > Inputs
• Work Performance Information
• Technical performance measures
• Project deliverables status
• Schedule progress
• Cost incurred
16

Perform Quality Assurance > Tools and Techniques
• Quality Audit
• Structured review of quality management activities
• May be in-house or independent
• Identify all the good /bad practices being implemented
• Identify all gaps/shortcomings
• Share the good practices introduced or implemented in similar projects
in the organization and industry
• Proactively offer assistance in a positive manner to improve
implementation of processes to help the team raise productivity
• Highlight contributions of each audit in the lesson learned repository of
the organization
17

Perform Quality Assurance > Tools and Techniques
• Process Analysis
• Follows the steps as specified in the process improvement plan
to identify the improvements from an organizational and
technical standpoint
• Looks at the problems encountered, constraints experienced
and other non-value added activities identified
• Root Cause Analysis

• Histogram
A histogram (or frequency
distribution chart) is a bar graph
that groups data by
predetermined intervals to show
the frequency of the data set. It
provides a way to measure and
analyze data collected about a
process or problem, and may
provide a basis for what to work
on first.

Perform Quality Control > Tools and Techniques
• Pareto Chart
The Pareto chart is a special type of histogram, used to view causes
of a problem in order of severity from largest to smallest. It is a
simple statistical tool that graphically shows the 20-80 rule where
20% of the sources cause 80% of the problems.

• Run Chart
Chronological order that displays changes and trends in the central
tendency (average)

Perform Quality Control > Tools and Techniques
• Scatter Diagram
A scatter plot is used for problem solving and understanding cause-
and-effect relationships. It shows whether a relationship exists
between two variables, by testing how one variable influences the
response (other variable).

Statistical Sampling
Selecting a portion of the population (0% - 100%)
Statistical terms
Mean – sum of measurements divided by number of measurements under
consideration
Median – value having as many observations above it as below it when the
observations are arranged in increasing or decreasing sequence of value
Mode – most frequently occurring observation
If two modes, considered bimodal
If three or more modes, not a viable measure of central tendency
28

Perform Quality Control > Tools and Techniques
Statistical Sampling (Continue)
Range – difference between the largest measurement and
the smallest measurement
Variance:
Population or process variance – sum of the squared
deviations from the mean divided by the number of
measurements
Sample variance – sum of the squared deviations from the
mean divided by number of measurements minus 1 (n-1)
Standard deviation – positive square root of the variance

Perform Quality Control > Tools and Techniques
• Inspection
– Inspections are formal manual techniques that are a natural
evolution of desk checking. This procedure requires a team,
usually directed by a moderator.
– Measuring, examining, and testing
– Determine whether results conform to requirements
– Conducted at any level

Quality Management > Some Important Concept
• Gold Plating:
– Giving the customer extras
– Adds no value to the project
• Just in Time (JIT):
– Decreasing inventory close to zero
– Forces attention to quality
• Total Quality Management (TQM):
– Company and employees focus on finding the ways to
continuously improve the quality of their business practices and
products
