How it Works

What our review covers:

Covering a series of key Engineering/ Manufacturing readiness & optimisation elements, we are able to generate and supply to you our Senior-level technical review of your design/drawing.

These steps are all present in each individual report, and include the core principles below:

GD&T & product definition

Are datums, tolerances and drawing requirements functionally correct and unambiguous, so a supplier and an inspector read them one way only?

Tolerance analysis & stack-up assesments

Will the design assemble and function as intended? Stack-ups that catch the interference before it appears at assembly, when a fix is at its most expensive.

Design for Manufacture (DFM)

Can it be made economically and consistently? Process, material and features checked against the intended method, before over-specification inflates every quote.

Design for Assembly (DFA)

Can it be assembled efficiently and reliably? Part count, accessibility and error-proofing, so the build doesn't invite misassembly and line-time cost.

Inspection & verification

Can every requirement be measured and verified as drawn, before it becomes a failed first article and a stalled acceptance after tooling?

Supplier interpretation

Whether the drawing reads one way only, wherever it lands. Ambiguity and cross-standard gaps between ASME and ISO environments are what turn into disputes, inconsistent quotes and rejected first article inspections.

Every finding is tied to the cost, dispute or delay it prevents, ranked by risk, with a recommendation your team can act on directly: a clear, defensible read on release readiness.

What You Receive

What the review returns:

1. A risk-ranked engineering report, focused on Design, Manufacturing & Quality.

2. Marked-up drawings, annotated directly

3. Prioritised recommendations, in fix-first order

4. A review meeting with your team


The Engineering Design Review is our flagship service.

It is comprised of an independent remote review of drawings, CAD, specifications and design intent against manufacturing, quality and inspection requirements, with one purpose, to identify the cost, quality and manufacturing risks in a design before release.

It returns the risk-ranked engineering report, marked-up drawings and prioritised recommendations above, closed with a review meeting.

Fees and turnaround are confirmed at scoping, and every engagement has a defined scope, a defined fee and a defined output.

Wider assessments and on-site engineering support are scoped individually on request.

Every finding is evidenced, risk-ranked and signed by a senior practitioner.

We identify, evidence and recommend; your design authority decides and implements.

The purpose; Elaborated

We review product designs to cut cost, tolerance risk & manufacturability problems before release.

We identify the design issues responsible for supplier disputes, non-conformances, failed first articles and assembly problems, before the drawing is released and the cost is unavoidable.

The core principle of our review is to ameliorate three Engineering KPI's:

Time, through fewer late engineering changes, fewer repeat tooling iterations and fewer disputes that stall a programme. Improve your operations efficiency.

Cost, found and removed at the drawing stage where it is cheap and effective; instead of recovered downstream where it is not.

Quality, through fewer rejections, less non-conformances and a reduction in first-article failures reaching production.

GeoTolerance is an independent technical review partner: Engineering Design Assurance specialists who confirm a product is ready for manufacture before expensive mistakes occur.

The outcome is maximising the probability for right-first-time manufacturing release whilst ensuring the aformentioned metrics are optimised in the process.
