1) “Quality by Design”(QBD)• The solutions offered by QBD
2) “Sequential Engineering”(SE)• Slow, Traditional Method
3) “Concurrent Engineering”(CE)• Fast, Multi-tasking Modern Method• Implementation
4) Applications5) ………..More to be added
I. What is “Quality by Design”?• “The practice of using a multidisciplinary team to conduct
conceptual thinking, product design, and production planning all at one time.” [T.Q.M. 349]
1) Incorporates:1) New Product Introduction(NPI)• The Introduction of a new product to market
2) Sequential Engineering philosophy• Compartmentalized engineering process where one department
fulfills their responsibilities, and then hands it off to the next repeating this process until the desired product is achieved
3) Concurrent Engineering philosophy• Is analogous to QBD• Parallel task are performed that would be sequential in SE
Classic Design ProcessCharacteristics:
Slow and InefficientWeak CommunicationTime demands
Evolution:Industry adapts old systems
to meet new demands “ Stage Gate Systems” “Product Funnels” “Concurrent Engineering”
All of these new systems package information to be passed on to other teams
[above] Sequential Engineering Modified with Data Packaging Steps at various stages
I. What caused the transition from SE to CE? Time became the deciding factor for success causing CE to emerge Budget Globalization brought more competitors to the market
II. Goals:1. Customers + (happiness\retention\communication\etc)2. Decrease time to market by overlapping different tasks3. Shorten the task being performed4. Decrease Cost “The bottom line”5. Increase Quality
III. Teams = Move the product from concept to market by performing a task1. Ex. Task = Marketing, R&D, Logistics, Test, Production, Quality 2. Everyone must work together towards a common goal
I. Pros: Faster than Sequential engineering Cooperative, Open exchange of information
“Decreases design changes” Decisions made with respect to different job
requirementsPromote internal communication
Customer service more connected to those with knowledge/solutions

Has three building blocks (foundation):Product DesignProcess DesignSupply Chain Design
3DCE is defined as:The simultaneous
development of products, processes, and supply chains.
Product DesignDeals with the product’s specifications
Process DesignConcentrates on methods to manufacture product
Supply Chain DesignIn sourcing, outsourcing, suppliers, and customersRelationship between organization and other
members of supply chain
3-DCADRapid PrototypingRapid Tooling
Some benefits in large companies in 1991Development and production lead time reductions
Product development time reduced by up to 60%Production spans reduced to 10%Total microelectronics fabricating process time reduced
up to 46%
Yield improvements of up to 4 timesField failure rates reduced up to 83%Improved quality of resulting end productsHigher reliability in the product development processIncreased customer satisfaction
Engineering changes per drawing reduced up to 15 times
Early production engineering changes reduced by 50%
Scrap and rework reduced up to 87%
New product ideas on hold
Pay workers to stand around while waiting on design changes
A last place competitor
More time to:Produce new product
ideas or improvementsBetter use of payrollStay ahead of the
competition
