Doors, Hardware & Access Control Manufacturing calculator
SKU Option Complexity Score Calculator
The SKU Option Complexity Score is a risk-priority number adapted from FMEA logic for openings manufacturers who configure doors, frames, hardware sets, keying, finishes and access-control devices into thousands of buildable SKUs. It multiplies how badly an option-mix error hurts the order (severity), how often that mix is ordered or mis-built (occurrence), and how likely your configurator or order review is to catch it before fabrication (detection). Estimators, configurator owners and quality engineers use it to rank which option combinations to simplify, lock down or add validation rules around. The higher the product, the more urgent the option family is to fix before it generates rework, field returns or non-conforming hardware sets.
What this calculator does
- Score complexity risk from door sizes, handings, swings, fire ratings, finishes, frame depths, lock functions, keyways, readers, and hardware-set variations.
- Use it when sku option complexity in doors, hardware and access control manufacturing needs a defensible ranking against other doors, hardware and access control manufacturing risks for the next review.
- It multiplies severity, occurrence and detection scores (each on the same scale) into a single complexity-risk number for an option family across door, frame, hardware, keying, finish and access-control choices.
Formula used
- SKU option complexity score = option mix impact severity score × option mix occurrence score × configuration detection control score
- Use the same scoring scale across door, frame, hardware, keying, finish, and access-control option risks.
Inputs explained
- Option mix severity score (1-10):
- Option mix occurrence score (1-10):
- Configuration detection score (1-10):
How to use the result
- Use it when triaging which configurable option combinations to rationalize, add configurator guard-rails to, or pull from the catalog before they cause mis-builds.
- The score is only as honest as your scoring discipline; inflated or inconsistent detection ratings across reviewers make scores non-comparable, so calibrate the scale before ranking SKUs.
Current U.S. benchmarks
- U.S. housing starts run at 1,177k per year (Census, May 2026), down 8.7% from a year earlier, the demand driver for building products.
- Steel mill PPI stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. New factory orders are up 2.3% year over year (Census).
Common questions
- How do you calculate a SKU option complexity score? Multiply the three sub-scores: severity x occurrence x detection. With severity 6, occurrence 4 and detection 3 the raw product is 72, and the calculator returns a normalized complexity index of about 4.55 on the displayed scale.
- What is a good SKU option complexity score for openings? Lower is better. There is no universal cutoff, but option families landing in the top quartile of your own catalog deserve a configurator rule, a simplification, or a mandatory order-review checkpoint.
- Why use severity, occurrence and detection instead of just a count of options? A raw option count treats a benign finish swap the same as a fire-rated keying mismatch. Weighting by severity, occurrence and detection surfaces the combinations that actually drive rework and field returns.
- How is detection scored for door and hardware configurations? Score how unlikely your current process is to catch the wrong option before fabrication. A configurator that auto-blocks an invalid frame/hardware pairing earns a low detection score; an option only caught by an installer in the field earns a high one.
- SKU option complexity score vs FMEA RPN: what's the difference? They share the multiply-three-factors structure, but this score is scoped to product configurability rather than process steps, so the occurrence factor reflects how often an option mix is ordered, not how often a machine fails.
