What is Craftsmanship? How well executed a given design is in the eyes of the customer. Synonymous with extreme attention to detail, done right the first time, pride in workmanship, and requiring a certain level of expertise and dedication to achieve. In manufacturing, craftsmanshipdirectly results from close communication between design, production, and skilled labor delivering quality product with pride. MPD575

What is Craftsmanship? The 'extra' effort expended that allows a final product to surpass the normal limits of utility and functionality, entering the dimension of art and beauty. The ability of skilled workers to put their final touch on the product based on their years of experience and creative artistic skills. Therefore, Design for Craftsmanship, DFC, is the ability of the product designer to allow for such creativity! MPD575

What is Craftsmanship? …harmony of the overall interior theme The art and execution of quality. It captures the customer’s perception of quality design and workmanship through sight, sound, smell, and tactile senses The blending of engineering, system architecting, and art to create a product that also has aesthetic appeal MPD575

Craftsmanship Is... a perception of quality materials weight/heft/solidity/sturdiness texture alignment tactility appearance compatibility with environment a perception that value is enhanced MPD575

Craftsmanship Is... What is a Perception? the electronic touchscreen could be an example of growth area, for transitions, speed, intrusion/asking approval, smooth response and touch response a result of perceiving: observation a mental image: concept awareness of the elements of environment through physical sensation <color perception> physical sensation interpreted in the light of experience Evaluated by the senses - Sight - Sound - Feel/touch - Smell - Taste - Emotion

Craftsmanship Is... Intangible (It Is Very Hard To Develop An Objective Metric) Attention To Detail Highly Associated With Brand Interpreted By The Customer The Result Of Specific Efforts MPD575

Craftsmanship Impacts… Things Gone Wrong Things Gone Right J. D. Power (or others’) Ratings/Surveys Customer Satisfaction Customer Loyalty Customer Perception of Quality MPD575

Craftsmanship Is Not... Measurable Quality R/1000, CPU Robustness Functionality Easily Quantifiable or Measurable MPD575

Craftsmanship Is Often Free It Costs Just As Much To Make It Ugly And Slapdash! Craftsmanship Requires More Up-front Thought But Can Be Cheaper In The Long Run (Well-routed Hoses Easier To Service, Etc.) Craftsmanship Is The Clearest Way To Show A Customer That The Entire Organization (From Design To Engineering And Manufacturing) Cares About Details. MPD575

Design For Assembly Craftsmanship Overlaps DFA In The Sense That If An Item Has Efficient DFA Then It Should Be Manufactured Such That It Meets The Design Intent. MPD575

Design For Manufacture In The Same Sense As DFA, Craftsmanship Overlaps DFM - If An Item Has An Efficient DFM Then It Should Be Manufactured Such That It Meets The Design Intent. MPD575

Robustness Tools Design Of Experiments Reduce Variation Find The Key Contributors Control What Can Be Controlled Process Controls Establish What Can Be Controlled Monitor Those Items Take Action When Out Of Control MPD575

Robustness Tools Eliminating Excessive Variation In Key Processes Improves Craftsmanship Process Outputs That Impact Fit/Finish/Function Will Drive Customer Perceptions Gaps Between Parts Operating Efforts (Doors, Toolbox Lids, Etc.) MPD575

Assembly Influences Operator Dependence This Is The Manufacturing Side Of Craftsmanship Taking The FMEA Approach And Assuming The Process And Design Have Been Optimized To Reduce Operator Dependence, Operators Must Be Trained And Motivated To Assemble The Product As The Designer Intended Ergonomics, Work Practices (Job Rotation, Skill Enhancement, Work Teams) All Play A Major Role MPD575

Assembly Influences Jigs And Fixturing This is a subset of DFA And DFM and helps reduce or eliminate operator error Poke-yoke (Pronounced Poh-kah Yoh-kay) Japanese practice that means elimination of error through mandating design of product and/or tooling such that error is impossible. MPD575

Artistic Design/Influences Automotive Design Appearance Harmony The artistic side of craftsmanship where beauty is in the eye of the customer and sometimes just the designer The Artist tries to interpret “The intangible needs of the customer” - “The engineer figures out how to bring it to market” MPD575

Artistic Influences Appearance This is completely the industrial designers’ world Appearance is highly tied to brand expectations (especially in automotive) Designers try to bring the customer a “sense” of the brand. Try to see if you can guess what the designer had in mind on the next slides... MPD575

Flushness Due to build variation, manufacturing cannot consistently obtain the perfect theoretical flushness condition However, variation is known Also, which flushness condition looks “worse” is also known Therefore, the vehicle can be built in a nominally underflush / overflush condition so the parts are always assembled in an aesthetically acceptable way
Margin and Flushness

Roof Liftgate
Under-flush condition

Margin and Flushness Flushness – Cheated Panels Hoods should rigidly remain in their latched position with little to no flutter The latched area is designed to pull away from the latch The areas of the hood bumpers are designed to push into the bumpers The strut forces are also compensated for Hood in Latched Position Hood As Manufactured Bumper Latch

Margin and Flushness Flushness – Cheated Panels Latch-able components like hoods, deck lids, liftgates, and side doors have a variety of forces being applied to them. Struts, bumpers, and seals will displace the sheetmetal a given amount In order to compensate for this, the sheet metal panel geometry is manufactured in a “cheated” position Liftgate struts can have several hundred lbs of force on the liftgate while in it’s latched position Strut forces on hatch-back Liftgate sheet metal is formed in the direction opposite the strut forces to achieve as designed flushness targets Roof - Body - Strut - Liftgate

Craftsmanship for Automotive Seats

Craftsmanship as applied to Automotive Seats Definition of craftsmanship from Oxford Dictionary:CRAFTSMANSHIP is the degree of skill in doing a task or of finish in the product made.Craft: skill, ability, ingenuity, art, talent, mastery, expertise, genius, handiwork The first point of contact between any vehicle and the occupant is the seat. A finely crafted seat invites the customer to sit and experience the comfort and fineness of the seat. A poorly crafted seat does not appeal to the customer, and will cause the potential loss of a sale. Craftsmanship is an attribute in the design process which targets the customers perception of vehicle quality (fit, finish and execution) and functions designed for user friendliness. It covers what a customer sees, touches, uses and hears.

Elements of craftsmanship and flow process

Design Guidelines typically employed Seats designed with the "cleanandneat" look, where the trim cover sew line (style and location) and seat geometry (foam and structure) are well suited for each other; Seat tracks rounded-off with sleek styling that eliminates or hides sharp edges and covers lubricated surfaces so that fingers can't get pinched and clothes can't be soiled. Designed attractively; such that side shields may not even be necessary to cover the seat track mechanism. Operates with low efforts, glides very easily, smooth, quiet and precise. Mounted in a manner to maximize rear occupant foot and leg room when the seat is adjusted to any position.

Craftsmanship as applied to Automotive Seats Seat controls that are: Located for easy accessibility at any seat position, with low operating efforts for quick and quiet adjustment. Styled to blend in with the surrounding components with no exposed mechanisms or screws. Shape and size of controls are user friendly with no accessible underside surfaces that are sharp Have structural ribs or have metal

Craftsmanship as applied to Automotive Seats Seat Craftsmanship is the customer's overall perception of Seat Quality in: the consistency of theme ... (what the customer sees) the efficiency & cleverness of design ... (what the customer uses) the attention to details with the desire to please ... (what the customer touches) the robustness and reliability of each component ... (what the customer hears). Craftsmanship is hard to measure objectively; but if you see it ... you recognize it. What craftsmanship is NOT;It isn't measured by the number of Seat functions or options,or the complexity of manufacturing process used,or the level of technology employed.

Mustang: Wrong Direction over Time? Cost And Craftsmanship May Correlate The Following Is A Comparison Of Some Exterior Mustang Craftsmanship Issues (1994-2002) MPD575

1994 vs 2002 Mustang Brake Light Is Incorporated Into The Spoiler Providing A “Clean” Appearance. Taillight Modules Color Matched To Body. Common Theme Of Smooth Horizontal Lines. Brake Light Is 3X Larger And Incorporated Into Trunk. Tail Light Modules, Fascia Perforations And Cut Lines Do Not Appear To Have A Common Stylistic Theme. Redesigned Quarter Panel And Unpainted Mirrors Emphasize Gaps And Incongruent Fit. Door, A-pillar, Quarter Panel Intersection Is Smooth Due To Painted Mirrors And Panel Design. Functional Air Vents For Improved Aerodynamics As Well As Styling. Non-functional Painted Plastic Appliqués Are Subject To Quality And Durability Concerns. MPD575

B A The “Cut Lines” Within Each Stamping Do Not Match Up With The Interfaces Between Body Panels. In Example A The Relationship Of Quarter Panel To Fascia Appears To Be Incongruent. In Example B, Hard Lines Caused By The Accentuated Fender Lip Break The Cut Line That Travels The Length Of The Body. In The 2002 Model, The Door Handle Is An Extremity To The Body Side. The 1994 Model Is Recessed And De-emphasized As Captured On The Previous Slide. MPD575

Assessment Process How Do You Measure Craftsmanship? Determine Attributes Of Product To Measure Use A Weighted Average Assessment Scale Weighting Of Attributes: 0-5 (0 – Unimportant, 5 – Important) Evaluate Product Against Attributes: Scoring Of Product: 0-6 (0 – Worst, 3 – Industry Average, 6 – Best) MPD575

Assessment Process Is It Best Performed By One, The Few Or The Many? Because Of The Subjectivity Involved, It Is Best Performed By As Few People As Possible They Should Remain Autonomous To Minimize Influences They Perform The Analysis Of The Entire Industry Under Review For Consistency They Are “Trained Eyes” That Know What To Look For, Know What The Customer Expects, And Know How Much Weight To Apply To It MPD575

Assessment Process Let’s Try An Example Underhood Of A Vehicle MPD575

Perceptions Count Underhood appearance is good or bad, depends on your opinion. VW and BMW can have great underhood appearance, but very few see or care from experience. So is poor underhood appearance worth effort and (yes the BMW level costs money) worth it? Plastic covers are compromise to hide things. A functional snow pack shield or NVH dampening cover is sometimes justification for “craftsmanship”. The GTDI twin turbo engine is as much an NVH cover as an appearance cover for a great performance engine! MPD575

Assessment Process The Coordination Of Hoses And Wiring Routings Is The Attribute Of Interest Subjectively, This Attribute Is Assigned A Weighting Factor Of 5 Each Car Is Rated From 1 (Poor) To 6 (Superb) MPD575

Assessment Process What Is The Score? Few Hoses Visible Layout Seems Somewhat Well Thought Out Coolant Recovery Hose Seems To Just Lay Across Everything Else Score: 3 Car #1 MPD575

Assessment Process What Is The Score? Few Hoses Visible Layout Seems Somewhat Well Thought Out Hose/Wire Routing Is Neat And Organized And Parallel To Each Other Score: 5 Car #5 MPD575

Assessment Process What Is The Score? Very Few To No Hoses/Wires Visible Layout Seems Very Well Thought Out Score: 6 Car #6 MPD575

Assessment Process MPD575

Assessment Process Total All Attributes Highest Score Shows The Best Vehicle MPD575

Assessment Process Summary Try To Find The Areas Of Craftsmanship That The Customer Values Over The Others And Spend Time And Money In Perfecting These Items These Expenditures Can Be Decreased By Using Carry-over Parts That Are Known To Achieve High Craftsmanship Ratings Do Not Spend Time And Money On Items The Customer Does Not Value Or Cannot See MPD575

Fonts Are Large, Clear And Easy To Read Grains Hide Imperfections In Molding Process Poor Alignment Hubs Cover Interface Between Stationary And Moving Parts Mask Covers Edges Of Appliqué Assessment Process High Craftsmanship Value Parts Extra Efforts Are Spent In Perfecting The Surface, Color, And Texture Of An Instrument Cluster, Because It Is Something The Customer Always Sees When Operating The Vehicle MPD575

Bezel Provides A Clean, Smooth Edge Allows Tactile Feedback Backlit For Operation In Low Levels Of Light Assessment Process Standard Craftsmanship Parts Efforts Are Spent To Select A Material And Apply A Texture That Allows Operation In The Coldest Of Temps While Not Showing Finger Prints For Security Reasons MPD575

Material Flow Swirl And Sink Marks Assessment Process Low Craftsmanship Value Parts This Electronic Module Is Packaged Behind The Trim And Is Not Visible To The Customer. Minimal Efforts Were Applied In Perfecting The Surface, Color Or Texture Of This Housing MPD575

Assessment Process Conclusions Spend Additional Resources On Parts And Interfaces That Have High Customer Value Spend Little Resources On Parts And Interfaces That Have Little Customer Value It Is All A Trade-off In The End And The Law Of Diminishing Returns Is In Effect MPD575

A Final Warning Some Craftsmanship Choices May Impact Other Engineering Trade-offs Underhood Beauty Cover Impacting Air Flow And Heat Management Fountain Pen Material Choice Will Impact Cost And Fabrication Technique (Wood vs. Plastic vs. Metal) MPD575

Other DFC Considerations Certain vehicle components, if replaced, could cause collateral damage to adjacent systems that depend on the component in OEM form. Example: Underbody shield with cooling ducts being replaced with a skid plate using no ducts can result in overheating The designer should use caution when selecting fasteners. Joints or components which must not be tampered with need to either A: Eliminate the joint/interface B: Use fasteners which cannot be removed by common tools C: Use one-way fasteners C: Prevent the user from disassembling the system down to the component level (Ex: use press fit on a water pump shaft to prevent replacement with a substandard part)
