PMBOK® – Project Quality Management
(PQM)

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.
It implements the quality management system through
policy and procedures with continuous process
improvement activities conducted throughout, as
appropriate.

PMBOK® – PQM Processes



Plan Quality
 Determining which quality requirements and/or standards are
important for the project and the product and then documenting
how compliance will be demonstrated.
Perform Quality Assurance
 Provides the basis for continuous improvement by auditing and
evaluating the results from quality control measurements so that
appropriate quality standards and operational definitions are used.

Scientific Management

Fredrick W. Taylor (1856 – 1915)

Management would set arbitrary rules of thumb
 Workers produced so much each day – no more,
no less
 Believed the production process could be more
efficient
 Break
a task down into smaller tasks & study it to find
the best and most efficient way of doing it
 Time – motion studies

10-11
Did not sit well with labor unions because many
ignored the human factors & believed profits
could be increased by speeding up the workers

6-Sigma D-M-A-I-C Cycle

Define


Measure


With data in hand, the team can analyze the data for trends, patterns, or relationships.
Statistical analysis allows for testing hypotheses, modeling, or conducting experiments.
Improve


The Six Sigma team is responsible for identifying a set of relevant metrics.
Analyze


The first step is to define customer satisfaction goals and subgoals; for example, reduce
cycle time, costs, or defects. These goals then provide a baseline or benchmark for the
process improvement.
Based on solid evidence, improvements can be proposed and implemented. The MeasureAnalyze-Improve steps are generally iterative to achieve target levels of performance.
Control

Once target levels of performance are achieved, control methods and tools are put into
place in order to maintain performance.

6-Sigma Roles & Responsibilities

Master black belts


Black belts


Should be technically competent and held in high esteem by their peers. They
are actively involved in the Six Sigma change process.
Green belts


People within the organization who have the highest level of technical and
organizational experience and expertise. Master black belts train black.
Are Six Sigma team leaders or project managers. Black belts generally help green
belts choose their projects, attend training with them, and then assist them with
their projects once the project begins.
Champions

Leaders who are committed to the success of the Six Sigma project and can
ensure that barriers to the Six Sigma project are removed. Usually a high-level
manager who can remove obstacles that may involve funding, support,
bureaucracy, or other issues that black belts are unable to solve on their own.

The Capability Maturity Model
Integration (CMMI)


Developed by the Software Engineering Institute at
Carnegie Mellon University in 1986
Mitre Corporation and Watts Humphrey developed a
framework to assess and evaluate the capability of
software processes and their maturity

Called the Capability Maturity Model (CMM), but has evolved
to the CMMI which is not limited to a specific area but can be
used across different disciplines

Immature Software Organization






Software processes are improvised
Or not followed!
Managers continually “fight fires”
No basis for judging quality
Schedules & budgets are usually exceeded
Functionality & quality often compromised to meet
schedules
10-27
Copyright 2012 John Wiley & Sons, Inc.
Mature Software Organization





Has organization-wide ability to manage software
development
Software process is communicated to staff
Processes are consistent with the way work gets done
Processes are updated when necessary
Roles & responsibilities are well-defined
10-28
Copyright 2012 John Wiley & Sons, Inc.
Other CMMI Concepts

Software process
 A set of activities, methods, or practices and transformations used by people to
develop and maintain software and the deliverables associated with software projects.
Included are such things as project plans, design documents, code, test cases, user
manuals, and so forth.

Software process capability
 The expected results that can be achieved by following a particular software process.
More specifically, the capability of an organization’s software processes provides a way
of predicting the outcomes that can be expected if the same software processes are
used from one software project to the next.

Software process performance
 The actual results that are achieved by following a particular software process.
Therefore, the actual results achieved through software process performance can be
compared to the expected results achieved through software process capability.

Software process maturity
 The extent to which a particular software process is explicitly and consistently
defined, managed, measured, controlled, and effectively used throughout the
organization.

Copyright 2012 John Wiley & Sons, Inc.
CMMI

Level 1: Initial


Characterized by an immature software
organization in which the software process is ad
hoc and often reactive to crises. Does not have a
stable environment for software projects, and
success of a project rests largely with the people on
the project and not the processes that they follow.

Software Testing Approaches
Unit Testing Focuses on the module, program, or object level to determine whether
specific functions work properly.
•Black Box Testing – Tests the program against specified requirements or
functionality.
•White Box Testing – Examines paths of logic or the structure inside a
program.
•Gray Box Testing – Focuses on the internal structure of the program.
Integration
Testing
Tests whether a set of logically related units (e.g., functions, modules,
programs, etc.) work together properly after unit testing is complete.
Systems
Testing
Tests the system as a whole in an operating environment to verify
functionality and fitness for use. May include tests to verify usability,
performance, stress, compatibility, and documentation.
Acceptance
Testing
10-43
Certifies that the system satisfies the end user or customer’s scope and
detailed requirements after systems testing is complete. It is the user’s or
client’s responsibility to assure that all features and functionality are
included so that the project’s MOV will be achieved.

Change, Control, & Configuration
Management

Changes to the project work must be managed





What changes were made?
Who made the changes?
When were the changes made?
Why were the changes made?
Configuration management includes a set of processes and
tools that allow the project team to manage its various
documents and files as various configurations of IT solutions
and project deliverables are derived. It may include specifying
and enforcing various policies that restrict access to specific
individuals or preventing two people from changing the same
document or file at the same time.
10-44
Copyright 2012 John Wiley & Sons, Inc.
Quality Control Activities
Quality Control Activities should focus on the inputs
and outputs of each process.
