Quality and Innovation in Product and Process Design
1. Generate Product Ideas
external sources: customer, industry experts consultants, competitors, suppliers, inventors internal sources:marketing, mgmt, research and development, employee suggestions
QFD Process - flowchart/house diagram
flowchart/house diagram
kano model shows quality is a function of
fulfilling customer requirements and achieving high levels of satisfaction
key elements: hows
how do you satisfy the customer whats product requirements satisfying customer needs
Key elements: customer reqts
how important the WHATS are to the customer customer ranking of their needs voice of the customer
key elements: what
identify customer attributes -what does the customer want, need voice of the customer
Building the House of Quality
identify customer attributes identify design attributes/reqts relate the customer attributes to the design attributes -conduct an evaluation of competing products -evaluate design attributes and develop targets determine which design attributes to deploy in the remainder of the process
add market evaluation and key selling points
identifying importance ratings for each customer attribute and evaluating existing products/services for each of the attributes
information: correlation matrix
impact of the hows on each other conflict resolution
information: target direction
information on the hows (more, less, specific amount) "the best direction"
key elements: relationship
relating customer and design attributes -strength of the interrelation between the whats and the hows untangling the web
performance:
reqts that customer can articulate and are at the top of their minds, and used to base decisions off of.
basic:
reqts that customer expects, they are taken for granted, when done well, customer is just NEUTRAL, when done poorly, customer is dissatisfied.
key elements: technical importance
select design attributes to be deployed in the remainder process -which hows are key? ranking the hows
information: how much
target values for the hows consistent comparison
2. Project Customer Needs
using data to predict future customer needs
kano model - expected needs
-entry level expectations are the MUST level qualities, properties or attributes -fully satisfying the customer at this level simply GET a supplier into the market -aka DISSATISFIERS bc by themselves they cannot fully satisfy a customer -failure to provide these expectations will cause dissatisfaction -ex. attributes relative to safety -MUSTS include customer assumptions, expected qualities, expected functions and other unspoken expectations
Designing products for quality
-functions customer wants -capabilities of current prod -limitations of materials selected? -are better materials available? -cost to make product -how much should it cost to be successful in marketplace
when is QFD appropriate?
-poor communication and expectations get lost in the complex product development cycle -lack of structure or logic to the allocation of product dev resources -lack of efficient &or effective product/process dev teamwork -extended development time caused by excessive redesign, problem solving or fire fighting
designing processes for quality
-services customer wants -steps of the current process -limitations of the procedures we have for the process -are there better procedures? -cost of process to perform -how much should process cost to be successful in marketplace?
benefits of QFD
-shorter development cycles -tradeoffs are made in design, strategically rather than in the market, tactically -lower costs, increased productivity -documentation orientation -team involvement and commitment at the design stage
kano model - normal needs
-these qualities attributes and characteristics KEEP a supplier in the market -aka WANTS/SATISFIERS because customers will specify these expectations from a list -can either satisfy or dissatisfy the customer depending on their presence or absence -wants include voice of the customer reqts and other spoken expectations
kano model - exciting needs
-wow level qualities -qualities and features that make a supplier a leader in the market -aka DELIGHTERS /EXCITERS bc they go beyond the customers imagination -absence does not hurt sales but presence improves likelihood of purchase -Wows excite customers to make on the spot pruchases and also return for future purchases -unspoken way of knocking socks of customer -ie.100,000 mile warranty
9 Steps to the design process
1. Generate Product Ideas 2. Project Customer Needs 3. Technology Feasibility Statement 4. Process Tech Selection 5. Final Product Definition 6. Marketing Plan Design 7. Product Evaluation 8. Manufacturing system Design 9. Manufacture, Delivery, and use
QFD's House of quality diagram
1. customer needs 2. importance rankings 3. design attributes 4. relationships btwn customer needs and design attributes 5. customer perceptions 6. correlation matrix 7. costs/feasibility 8. engineering measures
kano model - useful for gaining understanding of customer's needs -customers ACTUALLY do know what they want!! :)
1984- professor Noriaki Kano, categorize customer preferences into 3: the different needs have a different impact on customer satisfaction when fulfilled or unfulfilled. model applies to products, services, business processes and software
key elements: completeness
are all the hows captured?
QFD-quality function deployment
defined by voice of CUSTOMER, while the specification traditional approach is defined by the voice of ENGINEER
excitement:
delighters: unexpected and pleasant surprises. they are the innovations that differentiate your product. don't cause any disatsifaction when theyre not there because customer didnt expect them!
cascading the voice of the customer
design attributes=functional reqts component attributes=part characteristics process operations=manufacturing processes quality control plan=key process variables
3. Tech selection for product development
designers choose the best materials and technologies that will provide the best performance for the customer at an acceptable cost --> tech feasibility assessment
four houses of quality
diagram
using the house of quality
the voice of the customer MUST be carried throughout the design process 3 other houses of quality are used to do this and together with the first, these carry the customers voice from its initial expression, through design attributes, on to component attributes, to process operations, and eventially to a quality control and improvement plans -in japan all four houses are used -the tendency in the west is to use only the first one or two
