Fact I

Design is a tiny piece of the development pie, but itlocks in the bulk of later cost and time spending.

NCKU-IME-EE&I

Fact II

According to “Pareto Rule”,“Product design and process development”is the most critical product life cycle activity.

But, will a Good Design be a GoodProduct?

Concurrent Engineering

Definition of Concurrent Engineering

Concurrent engineering:“is a systematic approach to the integrated, concurrent

design of products and their related processes,including manufacture and support. This approach isintended to cause the developers, form the outset, toconsider all elements of the product life cycle fromconcept through disposal, including quality, cost,schedule, and user requirements.”Institute for Defense Analysis (IDA) R-338, 1986

Various applications

Multi-functional teaming

Communication, coordination and information sharing

Product is the goal

Models, methods, metrics, and measures are the core

Distributed and integrated decision process

Knowledge intensive

Massive & diverse types of information

Where is PDM in the EnterpriseInformation System

Where is PDM in the EnterpriseInformation System (SAP’s view)

Definition I

PDM is a tool that provide a structure way toorderly and efficiently store, integrate, manage andcontrol both data and the product developmentprocess (from design, manufacturing to distribution).

Definition II

A productivity tool for an entire business enterprisewhich:

Manages all product-related informationManages the entire product life cycleAllows information sharing regardless of

data location or hardware platform

Definition III

A PDM system is used within an enterprise to:1) organize, access, and control data related to its

products, and2) manage the life cycle of those products.

Definition IV

PDM systems provide access and security controls,maintain relationships among product data items,rules that describe data flows and processes, andnotification and messaging facilities.

PDM Justification Roadmap

Steering committee/board commitmentForm PDM project evaluation teamPerform a detailed cost/benefit analysisProvide initial educationPerform a requirements analysisSelect the best solutionSubmit for board/committee approval

NCKU-IME-EE&I

Steering committee/board commitment1. PDM should be seen as part of the overall strategy of the company2. Use a participatory approach - involve all key personnel3. Include managers with full authority4. Have board/committee provide all necessary resources

Form PDM project evaluation team1. Use a full-time leader with good coordination ability2. Team should have proper status and authority3. Team members should have knowledge in all technical areas,

or obtain externally through education and training

Perform a detailed cost/benefit analysis

Provide initial education1. Ensure ongoing education throughout the project

Perform a requirements analysis1. Use consultants if required2. Define the system's goals, objectives and constraints3. Generate a requirements specification4. Clearly define training needs5. Define appropriate vendor support6. Evaluate software vendors

Select the best solution1. Based on the requirements specification2. Test a maximum of three software demos with company-specific data3. Perform system testing (unit, module and user level)4. Ensure proper documentation is included5. If needed, change old hardware

Submit for board/committee approval1. Include full justification2. Include benefits appraisal3. Outline phased implementation plan4. Ensure commitment to project

Rules for PDM Implementation

Examine your motivation in looking at EDM andprioritize the requirements you have previouslyspecified.Understand the nature of your organization and the

implications this imposes on your choice ofsolution.Evaluate possible solutions carefully.

NCKU-IME-EE&I

Rules for PDM Implementation (cont.)

Build and test a pilot system having first defined thescope of the pilot implementation to ensure theoriginal objectives are met.Get the fundamentals correct at the pilot stage --

don't leave them till later.Do not ever assume you are finished.
