## Tool

**Kind:** checklist

**Scoring Note:** Mark each item that you have confirmed. Items flagged critical should be resolved or documented as an assumption on the quote before it is released.

**Groups:**

#### Drawing and data package

**Items:**

**Text:** Drawing, revision and date are identified and match the RFQ

**Critical:** true

**Text:** Bill of materials with manufacturer part numbers is included

**Critical:** true

**Text:** Wire list or from-to table matches the drawing

**Critical:** true

Overall and branch lengths and tolerances are stated

Pin-out and connector orientation views are present

Any 3D, board layout or routing model is available if required

Conflicts between drawing and BOM are listed as questions

Revision control for future changes is agreed

#### Workmanship and test

**Items:**

**Text:** Workmanship standard and class are stated

**Critical:** true

**Text:** Electrical test requirements (continuity, hipot, insulation resistance) are defined

**Critical:** true

Crimp requirements (height, pull, cross-section) are specified

Solder, splice and shield termination requirements are identified

Inspection plan and sampling requirements are known

First article inspection is required or not

Customer source inspection or witness points are listed

Test fixtures are customer-supplied or priced as NRE

#### Materials and sourcing

**Items:**

**Text:** All connectors, terminals and wire are available at reasonable lead time

**Critical:** true

Long-lead or single-source items are flagged

Alternates and substitutions allowed are defined

Customer-furnished material is identified, with receipt inspection terms

Material price validity and escalation terms are considered

Minimum order quantities for terminals and connectors are priced

Obsolescence or end-of-life parts are checked

Restricted-material requirements (RoHS, REACH, conflict minerals) are clear

#### Compliance and regulatory

**Items:**

Flammability, UL or other agency marking requirements are identified

**Text:** Export control status (ITAR or EAR) is confirmed with the customer

**Critical:** true

Controlled unclassified information handling requirements are defined

Country-of-origin or domestic-content (such as Buy American or Berry Amendment) requirements are checked

**Text:** Customer quality clauses and flowdowns are reviewed

**Critical:** true

Counterfeit-part prevention requirements are understood

Certificate of conformance and records retention needs are known

#### Commercial and delivery

**Items:**

**Text:** Quantities, release schedule and annual volume are stated

**Critical:** true

Packaging, labeling and shipping requirements are listed

NRE items are separated from piece price

Lead time includes material, FAI and customer approval time

**Text:** Payment, tooling ownership and warranty terms are reviewed

**Critical:** true

Quote validity period and cancellation terms are set

Assumptions and exclusions are written on the quote

## Content

**Intro:** A harness RFQ often arrives as a drawing, a spreadsheet BOM and a page of quality clauses, and gaps among them cause most of the quoting regret later. This checklist walks the package in the order an estimator needs it.

**Sections:**

#### How to use the checklist

**Body:** Go through the five groups before you finalize pricing. Tick what is confirmed, and for everything unclear either send the customer a question or write the interpretation into the quote assumptions. The critical items are those that, if wrong, change the price by a large amount or create contractual risk. Save the completed checklist with the RFQ so reviews are consistent between estimators.

**Bullets:**

- Do the review before costing, not after
- Send clarifications in one batch, not scattered across emails
- Convert unresolved items into stated assumptions
- Record who reviewed and the date

#### Why contract review matters

**Body:** Quality management systems such as ISO 9001 and AS9100 expect an organization to review requirements before committing to supply, including requirements the customer did not state but that are needed for the intended use. A structured checklist is a simple way to show that review happened and to keep estimators from repeating the same oversight, such as unpriced test fixtures or a flowed-down clause on counterfeit parts.

#### Where RFQs usually go wrong

**Body:** Drawing and BOM disagree on a connector or terminal part number. The class or test scope is not stated. A long-lead part has not been checked with the distributor. Export control or domestic-content requirements are discovered after the PO. NRE is expected to be free. Each of these shows up as a line item on this list so that it is raised while you can still decline, adjust the price or ask a question.

#### Common mistakes

**Body:** Quoting from a spreadsheet BOM without opening the drawing. Assuming alternates are acceptable. Not reading customer flowdown clauses until after the order. Combining unit price and NRE so that a canceled order leaves you with fixtures and no payment. Letting verbal clarifications stand without writing them on the quote.

**Cta:** If RFQ review and contract-review records currently live in email and spreadsheets, we can look at structuring them inside your ERP or quality system.

**Faq:**

#### What is the most important item on a harness RFQ review?

**Answer:** Matching the drawing revision, BOM and wire list, followed by the workmanship class and test scope. Errors in these change both cost and acceptance criteria, and they are the hardest to renegotiate after you have accepted the PO.

#### Do I need to ask about export control?

**Answer:** Yes if the program is defense related. Ask the customer whether the data or the product is subject to ITAR or EAR, because that affects who can handle the data, which suppliers you can use and how you transmit files.

#### When should I decline to quote?

**Answer:** Consider declining when critical data is missing and the customer will not clarify, when required capabilities such as a certified process are not in place, or when flowdown terms conflict with what you can commit to.

#### Where should I store the completed checklist?

**Answer:** Keep it with the quote and RFQ record so that when an order arrives, the assumptions and clarifications are available to production, quality and purchasing.
