The Purpose Of This Series
This is the last “connected” lesson in a 3–part series that explores the
integration of System Engineering (SE) and Earned Value Management
(EVM).
You don’t need to attend all three lessons – but it helps in Connecting
The Dots
Why have this series?
– Often, project control specialists see the planning of the cost and
schedule baselines as an isolated activity disconnected from the technical
or engineering aspects.
– This type of thinking significantly impacts development of the baseline
which results in poor maintenance and eventual irrelevance of the
baseline
– We claim “victory” if after any one of these lessons, you can recognize the
importance of integrating these disciplines such that he/she will advocate
greater cooperation between the engineering and project control
elements of his/her respective organization

Lesson 3 Objectives
In this lesson we will:
Understand how to establish credibility for
Technical Performance Measures by using Earned
Value and Systems Engineering to measure
progress
Establish the processes of defining and measuring
technical performance
Establish the role of the technical baseline in
program management
Learn how TPM’s are integrated into planning and
execution at the control account level through
examples and a hands on exercise

Can Earned Value Alone Get Us
To Our Destination?
How do we increase visibility into the program’s performance?
How do we reduce cycle time to deliver the product?
How do we foster accountability?
How do we reduce risk?
How do we start this journey to success?
Increasing the Probability of Success means we have to

Doing This Starts With Some Guidance
Systems engineering uses technical performance
measurements to balance cost, schedule, and
performance throughout the life cycle. Technical
performance measurements compare actual versus
planned technical development and design. They
also report the degree to which system requirements
are met in terms of performance, cost, schedule, and
progress in implementing risk handling. Performance
metrics are traceable to user–defined capabilities.

Guidance for Measures of
Effectiveness, Performance, and

Our starting point is not EVM, it’s Systems Engineering
MOE’s are an essential part of Systems Engineering,

Previous Approaches Using EV
Are Mostly Unsuccessful In
Connecting These
Traditional approaches to program management
are retrospective

– Risk Management
– Systems Engineering
Reporting past performance

It’s All Been Said Before.
We Just Weren’t Listening…
… the basic tenets of the process are the need for
seamless management tools, that support an integrated
approach … and “proactive identification and
management of risk” for critical cost, schedule, and
technical performance parameters.
― Secretary of Defense, Perry memo, May 1995
Why Is This Hard To Understand?
We seem to be focused on EV reporting, not the use
of EV to manage the program.
Getting the CPR out the door is the end of Program
Planning and Control’s efforts, not the beginning.

When We Put The Cart Before
The Horse, We Discover …
EVM really doesn’t do its job effectively
Most of the time EV has no measure of quality
or compliance with technical requirements.
EV measures progress to plan in units of
“money,” not tangible value to the customer
Most EV System Descriptions fail to connect the
dots between cost, schedule, and technical
performance – even though instructed to do so
in the official guidance

What’s Our Motivation for
“Connecting the Dots?”
TPMs are a set of measures that provide the supplier and
acquirer with insight into progress to plan of the technical
solution, the associated risks, and emerging issues.
Technical Performance Measures …
Provide program management with information
to make better decisions
Increase the probability of delivering a solution
that meets both the requirements and mission

63. CPM–500 EVM/SE/TPM Integration
Interesting Attributes of TPMs
Achieved to Date (sounds like EV)
Current Estimate (sounds like EAC/ETC)
Milestone
Planned (target) value (sounds like PV)
Planned performance profile (sounds like a PMB)
Tolerance band (sounds like reporting thresholds)
Threshold (yep, just what we thought)
Variance (sounds like variance!)
