• 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

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 OverviewGiven 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.

PerformanceCPM 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
