Overview of the elements of Lean Project Management, as well as an examination of the eight principles as outlined by Lawrence P. Leach in his book "Lean Project Management: Eight Principles for Success."

4. What Is Lean Project Management
Lean Project Management
(LPM) is “about simplifying
project leadership to satisfy
your stakeholders in the
shortest amount of time, while
minimizing stress on project
participants and waste.”

for Success. Boise Idaho: Advanced

5. What Is Lean Project Management
LPM relies heavily on
the PMBOK framework.
LPM focuses on
“Value”, as defined in
Lean, and on delivering
that value as quickly as
possible, using Critical
Chain Project
Management, first
described by Dr. Eli
Goldratt in his book
“Critical Chain.”

6. LPM: PMBOK
Lean Project Management focuses on the PMBOK
Knowledge areas that most affect delivering that
value quickly:
• Integration
• Scope
• Time
• Cost
• Risk
7. LPM: Lean Thinking
In the book “Lean Thinking”, Womack and Jones
coined the term “Lean”, following their analysis of the
Toyota Production System in “The Machine That
Changed the World.” They defined “Value” as the
elimination of waste from a process and outlined these
Five Principles:
1. Identify Value
2. Map the Value Stream
3. Create Flow
4. Establish Pull
5. Seek Perfection
Source: Womack (1996)
8. LPM: Lean Thinking
LPM seeks to deliver
project value as quickly
as possible, without
increasing cost, in order
to protect project ROI.
LPM identifies and
offers techniques to
eliminate the root
causes of waste in
project execution.
Eliminating waste is a
prime focus of Lean.

Eight Deadly Wastes of Lean
9. LPM: Critical Chain
• Founded on “Theory of Constraints” (TOC)
• Resource-based, not task based
• Uses buffers to manage variation/uncertainty
• Monitor project health based on consumption of
project buffer relative to remaining work
SOURCE: Goldratt, E. (1997). Critical Chain. Great Barrington, MA: The North River
Press, Inc.
10. LPM: Critical Chain
Reasons for Project Delays in Traditional PM
• Not starting the task until the last moment – and
often finding issues that delay completion
(Student Syndrome)
• “Work expands to fill the time allotted for its
completion” (Parkinson’s Law)
• Finishing the required task early but using
remaining time to add additional features (Gold
Plating)
• Cherry picking tasks

12. Eight Principles of LPM
The first two
principles form
the pillars of the
project delivery
system in LPM.

The last six principles outline the flow of the Project
Delivery Process, but in reality these principles
interact in both directions throughout the process.
13. Principle #1 – Project System
“Successful project delivery requires leading the
system, comprised of people, process, and product.”
(Leach, 2005)
Key Topics
• Project Management Methodology

16. Principle #2 – Leading People

Stakeholder 2 must have C. In order to have C, they must have D’
Stakeholder 1 must have B. In order to have B, they must have D
D and D’ are in conflict!

Each block is connected to another by an assumption. Insert this by
adding “because” – “In order to have B, I must have D because…”

on a project charter enables your project team to
succeed.” (Leach, 2005)

in the project, and whom do the key members report to?
Boundaries: What is in the project, what is out?
Key assumptions and constraints.
Team and individual responsibilities: For creating the Project Plan.
Measures of success: For the project.
Operating guidelines: For the project planning team.

23. Principle #4 – Right Solution
“Successful projects must deploy the right solution to
the problem or opportunity that the project seeks to
exploit.” (Leach, 2005)
Deploying the wrong solution is the worst kind of
project waste!

25. Principle #5 – Manage Variation
“Variation and uncertainty are the ways of the world:
to prosper, your management must go with the flow.”
(Leach, 2005)
Common Cause vs. Special Cause
Key Topics
• Reasons for Variation
• Buffer Management
• Project Tracking

Management Approaches to Various Types of Uncertainty

27. Principle #5 – Manage Variation
Critical Chain Method – The Problem
Task Duration Estimates are subject to variation – ex. -50% to +%100
A 50% confidence level in the estimate would result in less than 13%
probability of ending on schedule!
Therefore, “safety” is
added to the estimate
to give more margin
for error. However,
most of this margin is
wasted due to:
• Student Syndrome
• Parkinson’s Law
• Gold-Plating
28. Principle #5 – Manage Variation
Critical Chain Method – The Solution
Buffer is added equal
to 50% of the safety
removed (The theory
is, statistically half of
the tasks will end late
and half will end early,
averaging out.
Tasks are not date
driven – they depend
on the predecessor
task. Think of the
baton in a relay race.
Task Duration Estimates are reduced by 50% to eliminate safety at
the task level.
29. Principle #5 – Manage Variation
Buffer Management
SOURCE: Leach, L. (2005) Lean Project Management:
Eight Principles for Success. Boise Idaho: Advanced
Projects, Inc.
Project Buffer: A time buffer
at the end of a project
critical chain
Feeding Buffers: Time
buffers that connect non-
critical chains of tasks to
the critical chain
Resource Buffer: A
resource capacity buffer,
used in staggering the start
of project tasks
Cost Buffer: A dollar buffer
to comprise the total
estimated budget for a
project.

Green - doing fine, and
require no additional
management attention.
Yellow – team should
be creating buffer
recovery plans.
Red – team should be
implementing buffer
recovery plans.

31. Principle #6 – Risk Management
“Project risk management develops actions to
reduce the probability and potential undesirable
consequences of identifiable (special-cause) risks to
your project.” (Leach, 2005)
Managing Uncertainty
Key Topics
• Risk Management
• Risk Register
• Risk Matrix

33. Principle #7 – Project Plan
“The Project Plan provides all project stakeholders the
road map for project success. All projects require
necessary and sufficient project execution
procedures, including at least project communication
and change control processes.” (Leach, 2005)
“Do not mistake a project schedule for a Project
Plan”!
• Communications Plan
• Change Control
• Task Network

36. Principle #8 – Execution
“Relay racer task performance underlies the final
principle to Lean Project Management. Executing
Lean projects deploys the Lean principle of Pull to
cause projects to flow from start to finish with
minimal generation of waste.” (Leach, 2005)
“Tasks do not have due dates!”
