Critical parameter management

  1. 1. Enabling an Active Design Desktop with 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 Marketing Design Systems Engineering Subject Matter Experts MFG Suppliers Standards Partners Critical Parameter Management (CPM) Critical Parameter Management (CPM) CPM is a Disciplined Methodology to Capture the Product Performance into a Structured Repository Domains in Product Development SRM System Requirements Management Product Definition PCM Product Cost Management Affordability Definition CPM Critical Parameter Management Performance Definition PDM Product Data Management Configuration Definition • 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 The Active Design Desktop A-Spec B- Spec B2-HRD System “The System SHALL …” B1- SS Voice of the Customer Requirements Management Requirements Management is used to track, manage, and control requirements flow-down in a text based environment System Sub-System Component TPM / Req “The System CAN …” Sub-Assembly Critical Parameter Management Performance/ Design Capability 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 *The Excel, Crystal Ball, Minitab, and Matlab symbols are trademarks of their respective owners: Microsoft, Decisioneering, Minitab, and MathWorks.
