Introduction to Project Quality Management

Experts define Quality based on:

• Conformance to requirements: Project’s processes and

products meet specifications.

• Fitness for use: A product can be used as it was intended.

The concept addresses both:

– Management of the project

– Deliverables of the project

Every project should have a Quality Management Plan.

PMBOK 5E Ref #8.0

Quality vs. Grade

Quality is “the degree to which a set of inherent characteristics

fulfill requirements.” (PMBOK Guide 5th Edition definition –

glossary). It includes stated and implied needs.

Grade is a category assigned to products or services having the

same functional use but different technical characteristics.

For example, a software product can be of: High Quality (no

defects) and Low Grade (a limited number of features), or of Low

Quality (many defects) and High Grade (numerous features)

PMBOK 5E Ref #8.0


6 6

Accuracy vs. Precision

Accuracy is an assessment of

correctness. Accuracy means the

measured value is very close to the

true value.

Precision is a measure of

exactness.

Precision means the values of

repeated measurements are

clustered and have little scatter.

PMBOK 5E Ref #8.0


7 7


• The Project Manager and Project Team are

responsible for managing the level of Quality and

Grade

• The Project Team must determine appropriate

levels of Accuracy and Precision

PMBOK 5E Ref #8.0


8 8


Modern quality management complements project

management by recognizing the importance of:

Customer Satisfaction: Understanding, evaluating, defining,

and managing requirements to meet customer expectations.

The product or service must satisfy real needs.

Prevention over Inspection: Quality is planned, designed,

and built into the deliverables – not inspected in. The cost of

preventing mistakes is generally much less than the cost of

correcting them when they are found by inspection.

PMBOK Ref #8.0


9 9

Project Quality Management – cont’d

Management Responsibility: Management is responsible

for providing the resources needed to succeed.

Continuous Improvement: Initiatives such as the plan-do-

check-act cycle as defined by Shewhart/Deming; quality

initiatives such as TQM and Lean Six Sigma; process

improvement models such as Malcolm Baldrige,

Organizational Project Management Maturity Model (OPM3);

and, Capability Maturity Model Integrated (CMMI).

Cost of Quality (COQ): Total cost of conformance and non-

conformance work. PMBOK 5E Ref #8.0

Plan Quality Management

Plan Quality Management process:

• Identifies quality standards relevant to the project

• Documents how the project will demonstrate

compliance to the quality requirements

PMBOK 5E Ref #8.1


13 13

Plan Quality Management

Plan Quality Management process:

Key benefit of this process: It provides guidance and

direction on how quality will be managed and

validated throughout project.

Fundamental quality tenet: Quality is planned,

designed and built in – not inspected in.

PMBOK 5E Ref #8.1

Seven Basic Quality (7QC) Tools



22 22

1. Cause-and-Effect Diagrams

Also known as: Fishbone or Ishikawa Diagram:

• Illustrates how various factors might be linked to potential problems or effects - helps to better understand a problem and the contributing factors

• Effective tool for studying processes and situations - leads to better understanding of a process by generating detailed questions about it



23 23

2. Flowcharts

Also known as: process maps

• Shows activities, decision points and order of processing:

• Useful to understand and estimate cost of quality in a process

• Helps anticipate and analyze how, where and what problems

may occur



24 24

Flowcharts - SIPOC

Model

Flowcharts map

operational details of

procedures that exist

within a horizontal

value chain of a

SIPOC Model




25 25


3. Checksheets

Also known as tally sheets

used to:

• Organize facts to facilitate the

effective collection of useful

data about a potential quality

problem

• Gather attribute data while

performing inspections to

identify defects


PMBOK 5E Ref #8.1.2.3

26 26


4. Pareto Diagrams

• Special form of vertical bar chart used to identify vital few

sources responsible for causing most of a problem’s effects

• Categories on horizontal axis are a valid probability distribution

that accounts for 100% of possible observations

• Frequencies for each cause decrease in magnitude until ‘other’

accounts for non-specified causes

• Typically organized into categories that measure frequencies

or consequences



27 27



Pareto Diagrams

28 28


5. Histograms

• Special form of bar chart

• Used to describe the central tendency, dispersion,

and shape of a statistical distribution

• Does not consider the influence of time on the

variation that exists within a distribution (unlike the

control chart)




Histograms


30 30


6. Control Charts

• Visually display if the process (measurements) are in control

• Help to predict trends

• Main use of control charts is to prevent defects, rather than to

detect or reject them

• The upper control limit and lower control limit are generally +/- 3

sigma around a process mean set at 0 sigma

• Upper (maximum) and lower (minimum) values are based on

contract requirements. The values are set by Project Manager

and appropriate stakeholders to reflect the points at which

corrective action will be taken to prevent exceeding specification

limits.



31 31


6. Control Charts

• To monitor any type of output variable. For example:

– cost / schedule variations

– volume and frequency of scope changes

– errors in project documents

• Process is out of control if:

- Data point exceeds a control limit

- Seven consecutive points are above or below the

mean

• When a process is outside acceptable limits, the process

should be adjusted

7. Scatter Diagrams

Aka correlation charts - seek to explain a change in the

dependent and corresponding independent variable

• Dependent variables vs. Independent variables are plotted

• The plot can depict correlations

– inverse (negative)

– proportional (positive)

– no correlation (zero)

• If correlation exists, a regression line is calculated to

estimate pattern of relationship between two variables




36 36

Highly Negative Low to Moderate

• Allows analogies from projects in different area

Benchmarking



40 40

• Statistical method for products under development

• Framework for systematically changing elements of a

process

• Helps highlight influencing factors that reveal the presence of interactions and synergy among the factors

• Helps identify which factors may influence a product

variables

• Helps with optimization of products or processes

Design of Experiment (DOE)



41 41

• Involves choosing part of a population of interest for inspection

For example, selecting ten engineering drawings at random from a list of seventy-five

• Sample frequency sizes should be determined for including number of tests, expected scrap etc. (Cost of Quality)

Statistical Sampling



42 42

Used to better define the situation and manage quality:

– Brainstorming

– Force Field Analysis

– Nominal Group Technique

– Quality Management and Control Tools

Additional Quality Planning Tools

conforms or it

does not

Tolerances:

the result is

acceptable if it

falls within the

range specified

by the tolerance

Inspection:

keeping

errors out of

the hands of

the customer

Variable Sampling:

the result is rated

on a continuous

scale that

measures the

degree of

conformity

Quality Influencers - Other

• KAIZEN = Continuous Improvement (these two definitions are equivalent on the exam)

• JIT (Just in Time) : this is an approach to decrease the amount of inventory that a company carries, thereby decreasing the investment in inventory.

– A “just in time” philosophy directs a company to improve quality (forces attention to quality) because extra materials are not available.
