DFA/DFM Analysis Template for Excel

Description

Design smarter products, faster — without building a spreadsheet from scratch.
The DFA DFM Analysis Template scores any product design on two dimensions that drive cost: how efficiently it can be assembled (DFA) and how reliably it can be manufactured (DFM). Enter your parts once, and every efficiency, issue index, and yield figure updates itself.

What it does

• Calculates theoretical and practical part efficiency so you can see how many parts you could eliminate
• Scores four assembly issue indices — mistake-proofing, handling, insertion, further processing — against clear targets
• Rolls up process capability into an assembly-level yield (RTY) and short-term sigma level
• Flags problem parts automatically with red/amber/green status on a one-screen dashboard

What’s inside (5 linked worksheets)

• Summary Dashboard — every metric vs. target, at a glance
• DFA Analysis, DFM Analysis — the working scorecards
• Improvement Actions — prioritised short/medium/long-term log
• Instructions — method overview and how-to

Why this template
Built on the recognised Boothroyd-Dewhurst DFA/DFM methodology, with 78 live formulas already wired in, colour-coded input vs. calculated cells, drop-down validation, and a pre-loaded worked example so you can see exactly how it works before entering your own data.

Who it’s for
Design, manufacturing, quality, and Six Sigma engineers running design reviews, NPI, and cost-reduction / DFMA workshops.

What you get
