About ReworkCost.com
An independent reference for the cost of rework: the time, money and morale spent redoing software, manufacturing, construction and knowledge-work tasks that should have been done correctly the first time. Operated by Digital Signet, founded by Oliver Wakefield-Smith.
Why we built it
Rework is one of the largest hidden cost lines in any organisation: software bug fixes after release, construction defects, manufacturing scrap, document revision cycles, missed-spec deliverables. Most published guidance is from consultancies pitching root-cause-analysis services or quality-management certifications. This site exists to publish defensible cost-of-rework benchmarks across industries with the assumption set behind each band, and a calculator that translates project size into a working rework-budget figure.
Who runs this site
Oliver runs Digital Signet, an independent AI-development studio that builds data-led pricing and decision tools using public datasets. After 20 years as a solutions architect and tech lead across media, utilities, satellite, and data, he founded Digital Signet to apply autonomous AI development methodology to real software at scale.

About the studio
This site is operated by Digital Signet, an independent AI-development studio founded by Oliver Wakefield-Smith. It is part of a portfolio of consumer cost-reference and calculator sites we run as a live R&D lab for our Signet methodology, an autonomous AI development team that ships real software at scale.
Digital Signet does not sell quality-management software, does not run a Six Sigma certification practice, does not act as a process-improvement consultancy, and does not accept paid placements from any vendor in the quality-tooling space. Editorial direction is set by Oliver. Drafts are produced via Digital Signet's autonomous AI development methodology and reviewed against the editorial framework before publication.
For consulting enquiries (fractional CTO, AI product strategy, autonomous-dev-team setup): see digitalsignet.com.
What we hold to
- Source pattern. Built on public reference material across the relevant publisher landscape.
- No paid placements. Does not sell quality-management software, does not run a Six Sigma certification practice, does not act as a process-improvement consultancy, and does not accept paid placements from any vendor in the quality-tooling space. Independent of every named third party in the relevant space.
- Math is documented inline. Where the site has a calculator, inputs and assumptions are visible on the calculator page. Nothing is hidden behind opaque scoring.
- Update only when underlying reality changes. Triggers: New CII rework-cost research edition; Major Capers Jones / SEI software defect-cost dataset update; ASQ Cost of Quality survey re-publication; Material change in published manufacturing scrap-rate benchmarks.
