Critical Parameter Management
Executive Overview
What is Critical Parameter Management?
CPM Primary Program Benefits
Improve Collaboration
-Share technical analysis and knowledge
-Link ownership to parameters
-Mathematically connect parameters to understand requirement flow-down
-Capture and leverage invested intellectual capital for future business reuse
Facilitate Analysis
-Statistical modeling & optimization of the performance – cost trade space
-Real-time System-level sensitivity analysis
-Connect analyses between system, subsystem and component levels
Streamline Reporting
-Design margins are statistically tracked over product lifecycle
-Automated, real-time requirements data gathering / report generation
-Reconciliation of requirement allocation and engineering design capability

• A disciplined methodology for managing, analyzing, and reporting technical product performance
• A process for mathematically linking parameters for sensitivity analysis and optimization of requirements
• An “Active Design Management” system providing real time collaborative feedback of system performance behavior
• A strategic tool for improving product development by integrating systems, software, and hardware engineering

CPM is a mathematically interconnected hierarchy
of requirements and parameters allowing flow
down AND flow up of design sensitivities
The Active Design Desktop is
a Global Positioning System for
Product Development
CPM Enables the Active Design
Desktop through analytical
interactions between
requirements and parameters
Is CPM Just Like Requirements Management?
NO - CPM and Requirements Management are NOT the Same Process!
CPM has significant advantages over traditional requirements
management. A robust CPM process includes requirements
management as one piece but CPM allows requirements to be
connected to parameters in an analytical way
Traditional requirements management is a text based approach to
interaction with customer needs and regulatory compliance. CPM,
through its dynamic relationships between requirements and
parameters, provides real time feedback and notification throughout
the system about requirement or parameter changes as well as the
sensitivities of individual parameters on the overall system.

CPM captures corporate “tribal knowledge” along with best
practices and analytical reasoning, and provides complete
historical tracing for any process, system, or system of systems.
Motivation for CPM
• Enables a lean approach to to optimize product cost, performance, schedule, and manufacturability
• CPM means PREDICTING product performance and design characteristics before a system is actually built
• Provide complete history of design intent, rationale, input/output, thereby easing compliance requirements
• Leverage statistical design methods to allow for performance to be modeled in a PROBABLISTIC manner
• Re use of technical knowledge, capture of corporate TRIBAL KNOWLEDGE and intellectual capital
• Trace each design parameter to its corresponding Voice of the Customer
• Connect performance based design decisions with their COST IMPACTS early in the development process
• Connect design teams and encourage COLLABORATION between all disciplines around performance
•Connect various geographical sites
•Connect large numbers of engineers from various disciplines
•Provide a real time portal for managers to track the development process
The CPM process creates an Active Design Desktop
which allows engineers and management to:
• Query and access parameter information and relationships
• Create real time, dynamic program status reports
• Manage the many-to-many relationships of parameters
• Navigate/browse through the parameter function tree
• Manage all transfer functions , Y=F(x)
• Control access & ownership for design control
The CPM Active Design Desktop is a Single Point of
Control for Product Data and Knowledge:
• Launch -> Load -> Retrieve Parameters with Applications
• Manage Application Files, Engineering Models, and Capabilities
• Repository for Supporting Design Artifacts and Documents
The CPM Active Design Desktop is a process and
tool set that enables the improvement of product
design and reduction of program costs by:
• Providing a single go-to repository for all users to interact with
requirements and parameters in a real time collaborative
environment across the organization
• Reducing late-design firefighting due to inefficient collaboration
• Exposing and managing risks in product design and
manufacturing capability
• Identifying cost savings opportunities due to over-design
• Eliminating inefficiencies in program reporting
Methodology: CPM Process Overview
Given a System Level Requirement and/or a Voice of the Customer…
Ex: Range, Cost, Comfort, Force, Tone, Weight, Ease, etc.
• Allocate top-level requirements into sub-system/process and
component/raw material requirements that are given to designers to meet
• Each designer or team works independently to assess itself on how well it
is going to meet its allocation by building a model that predicts anticipated
design characteristics
• Teams identify which parameters are most sensitive to their requirements
and allocate appropriate resources for analysis
• Statistical parameters are added to provide confidence to the model and
predict top-level capability probablistically. “Can I meet the cost target”, v.
“Can I meet the cost target with 99% statistical confidence?”
• These parameters are rolled up from each designer or team using
transfer functions to provide a system-level prediction
• Where necessary, sensitivity analysis is conducted to focus efforts where
they have the most significant impact on system requirements.
Real time feedback on design
and total system capabilities
Where do I have design margin
and where am I at risk?
Design Convergence reports track
current parameter values v. their targets
←Collaborate
←Analyze*
←Report
This parameter can now answer
the famous question:
Who am I?
Why am I
here?
CPM, like these other product development domains,
provides a key repository for product knowledge and
becomes the “go to” location for all performance and
functional data for a system.
CPM helps the product or process development team trace the
connection between each key design decision and it associated
VOC (Voice Of the Customer). This helps ensure that the
development team works on the most important design elements
and lets the corporation re use product knowledge in future
generations of design.

Performance
CPM helps designs meet both cost and performance goals with predictive,
repeatable results based on analytical input. CPM also helps development
teams make informed decisions that optimize both cost and performance
throughout the development process. CPM lets teams answer important
questions such as: “If this requirement is being met, just how much
margin is there? Is it over-designed? Are there cost reduction
opportunities in this design?
Optimize Cost v. Performance
