Product Engineering, Specifications & Feasibility 16
- Which Development Gates Earn Their Place Premium Prices the bench, the laboratory panel, the pilot yardage and the held first bulk lot against the problems each of them catches and the cost of catching those problems one stage later instead. Returns the order quantity above which each gate pays for itself, and applies it across a development book that is almost always over-tested at the bottom and under-tested at the top. What the Right Gates Are Worth cost/yr
- Design of Experiments Factor & Run Planner Plans an economical factorial experiment: runs in the fractional design, total runs including replication and centre points, design resolution, effects estimable, total cost and time, and the saving against a full factorial. Total Runs Required runs
- Fabric Hand & Performance Specification Matrix Maps subjective hand onto measurable properties: deviation from target for bending rigidity, compression, drape, stretch and friction, the weighted total deviation, a composite hand index and the single property furthest from target. Composite Hand Index index
- Finished-to-Greige Dimension & Weight Back-Calculation Works back from a finished fabric specification to greige settings: required greige width and GSM, greige length per hundred finished metres, the area ratio shrinkage imposes, finish add-on mass and the greige length an order requires. Required Greige Width cm
- Material Substitution Equivalence Comparator Compares a proposed fibre substitute against the original: equivalence ratio on tenacity, moisture regain, density and cost, a weighted equivalence score, the fabric weight change density implies and the cost saving offered. Weighted Equivalence Score %
- Measurement System Analysis (Gage R&R) Calculator Separates equipment repeatability from operator reproducibility, combines them into total gauge R&R, and reports the result against both acceptance criteria — percent of study variation and percent of tolerance — plus the number of distinct categories the gauge can resolve. Gauge R&R (% of Study Variation) %
- Measurement Uncertainty Budget Builder Combines instrument, sampling, conditioning, operator and method uncertainties in quadrature to a combined standard uncertainty, expands it by the coverage factor, and reports the reportable interval around the measured value plus the share of variance owned by the largest component. Expanded Uncertainty U %
- Pilot-to-Bulk Scale-Up Readiness Checker Scores six scale-up dimensions — recipe, machine, sample, capacity, risk and commercial approval — against their weights, compares the result with the release gate, and reports the shortfall, the weakest dimension, the score that dimension alone would need, and how many sit below the critical threshold. Weighted Readiness Score /10
- Product Risk & Critical-to-Quality FMEA Matrix Ranks failure modes for action: risk priority number, criticality from severity and occurrence, the RPN after planned actions, the reduction achieved, margin over the action threshold and what detection or occurrence improvement would each achieve alone. Risk Priority Number RPN
- Product Specification Limits & Process Capability Builder Converts customer tolerances into specification limits and tests them against the process: upper and lower limits, capability index for mass and strength, the weaker of the two, and the process standard deviation each property would need to reach a target capability. Limiting Capability Cp
- Response Surface Operating Window Optimizer Finds the process window satisfying two opposing responses: the bound each specification imposes, the feasible band between them, the midpoint setting, both responses at that setting and the tighter of the two margins. Operating Window Width units
- Specification Tolerance Cost-of-Quality Modeler Prices a tolerance change: converts current and proposed limits into sigma levels and reject rates in ppm, costs the additional rejects across annual volume, and compares that against the process improvement needed to hold the tighter limit at unchanged capability. Additional Annual Reject Cost currency
- Target GSM to Yarn Count & Construction Solver Solves the yarn counts a target fabric mass requires: warp and weft count in Ne and tex, the mass each direction contributes, the warp share of fabric weight and the resulting cover factor. Required Warp Count Ne
- Technical Data Sheet Completeness & Control Checker Audits a technical data sheet before it is issued: coverage of test methods, tolerances and units across the listed properties, a combined completeness score, approval sign-off status, and whether the document is past its controlled review interval. Overall Completeness %
- Tolerance Stack-Up Calculator for Textile Specifications Propagates yarn, construction, process and finishing tolerances into a product tolerance: root sum square and worst-case stack, margin against the specification, the share of variance owned by the largest contributor, the tolerance it would need for a tighter spec, and the sigma level achieved. Root Sum Square Tolerance ± %
- Woven Construction Feasibility Checker Tests whether a target construction can be produced: reed dents per centimetre required, Peirce cover factor, total ends, and the margin available against reed density, cover factor and loom pick rate limits. Feasibility Margin ×
