WHAT ARE SPECIFICATIONS? PRECISE DESCRIPTION OF WHAT THE PRODUCT HAS TO DO LANGUAGE OF THE CUSTOMERS, SUSPENSION FORK SUBJECTIVE INTERPRETATIONS @ SUSPENSIONS REDUCES VIBRATION TO HANDS EASY HANDLING OF DIFFICULT TERRAIN HIGH-SPEED ON BUMPY TRAILS RIGID IN HIGH CORNERING PRIDE EASY MAINTENANCE LAST LONGER TIME SAFE IN CRASH

mountain bikes CUSTOMER NEEDS CUSTOMER NEEDS VS. PRODUCT SPECIFICATIONS

TECHNICAL/PRODUCT SPECIFICATIONS KEY DESIGN VARIABLES OF PRODUCT SUCH AS OIL VISCOSITY, SPRING CONSTANT OF SUSPENSION CONSISTS OF A METRIC AND A VALUE AVERAGE TIME TO ASSEMBLE (METRIC) LESS THAN 75 SECONDS (VALUE) FORMS OF VALUES; NUMBER A RANGE AN EQUALITY WITH APPROPRIATE UNITS (SEC., KG, JOULES) TOUGH BIKE

WHEN TO ESTABLISH SPECIFICATIONS AFTER IDENTIFYING THE CUSTOMER NEEDS, THE TEAM SETS TARGET SPECIFICATIONS REVISION OF SPECIFICATIONS, TO SET FINAL SPECIFICATIONS TWO STAGE PROCESS FOR ESTABLISHING SPECS EXHIBIT 6-3, PAGE 94

STEP 1: PREPARE LIST OF METRICS INDEPENDENT VARS. STEP 1: PREPARE LIST OF METRICS EXHIIBIT 6-4, PG. 96 LIST OF METRICS FOR THE SUSPENSION

THE NEEDS-METRICS MATRIX ONE METRIC, ONE NEED. EXHIBIT 6-5, PAGE 97

STEP 2: COLLECT BENCHMARKING INFORMATION

Competitive benchmarking With the most Stars

STEP 3: SET IDEAL & ACCEPTABLE VALUES IDEAL VALUE IS THE BEST RESULT THE TEAM COULD HOPE FOR ACCEPTABLE VALUE IS THE VALUE THAT WOULD JUST BARELY MAKE THE PRODUCT COMMERCIALLY VIABLE. CONCEPT GENERATION & CONSEPT SELECTION 5 WAYS IN STATING SPECS: >= AT LEAST [325 kN/m] <= AT MOST [suspension fork <= 1.4kgs] BETWEEN X AND Y [800 N >= x >= 480 N] EXACTLY Y=38MM A SET OF DISCRETE VALUES: radius 1.000, 1.125, 1.250 cm

STEP 4: REFLECT ON RESULTS & PROCESS TEAM MAY REQUIRE FEW ITERATIONS TO AGREE ON TARGETS (PRODUCTION SPECS VS QUALITY SPECS ETC.) IS THE GOAL SET TOO HIGH, SO THAT IF FALLS BACK STILL AT HIGH RANGE (MARKETING) OFFERING MULTIPLE PRODUCTS /MULTIPLE OPTIONS MISSING SPECS PROCEED TO SOLUTION CONCEPTS

SETTING FINAL SPECIFICATIONS TECHNICAL PERFORMANCE METRICS VS. COST

STEP 1: DEVELOP PRODUCT TECHNICAL MODEL TOOL FOR PREDICTING THE VALUES OF THE METRICS FOR A PARTICULAR SET OF DESIGN DECISION ANALYTICAL AND PHYSICAL APPROXIMATIONS OF A PRODUCT OIL-DAMPED COIL SPRING CONCEPT FOR SUSPENSION FORK DESIGN-OF-EXPERIMENT (DOE)

TECHNICAL FEASIBILITY

PROTOTYPES = TECHNICAL MODELS

STEP 2: DEVELOP PRODUCT COST MODEL

STEP 3: REFINE SPECIFICATIONS FINAL SPECIFICATIONS CAN BE ACCOMPLISHED IN GROUP SESSION FINAL SPEC PRODUCT = BEST AGAINST COMPETITOR, SATISFY CUSTOMER NEEDS & ADEQUATE PROFITS HOW TO DO THAT,  COMPETITIVE MAP @ TRADE- OFF MAP HIGH-PERFORMANCE SUSPENSIONS (LOW MONSTER SCORES) TRADE-OFF CURVES

COMPETITIVE MAP

FINAL SPECS

STEP 4: FLOW DOWN SPECS A PRODUCT IS MADE OF MANY SUBSYSTEMS, SUCH AS CAR & BICYCLE FLOW DOWN FROM OVERALL SPECS TO SUB SYSTEM SPECS ALL SUBSYSTEMS SPECS  OVERALL SYSTEM SPECS SOME SUBSYSTEM SPECS ARE DIFFICULT TO MEET THIS CAUSES THE COST OF PRODUCT TO BE HIGHER MEETING ENGINE SPECS IS MUCH MORE TOUGHER THAN MEETING CAR BODY SPECS

STEP 5: REFLECTION REMEMBER… TO REMEMBER WINNING PRODUCTS? UNCERTAINTY IN TECHNICAL MODEL AND COST CHOSEN CONCEPT IS THE BEST FOR MARKET? BETTER TECHNICAL MODEL FOR FUTURE
