Sample Development & Selection Collaboration

Sample Development & Selection Collaboration

When samples are needed to confirm feasibility, it is usually because the project schedule has tightened. The original part cannot arrive in time, or an alternative needs checking before it can be committed to. The most direct way to verify it is to get a physical sample and fit it.

Our approach at this stage is straightforward: once the requirement is received, we provide the alternative along with a drawing for your design team to evaluate, then ship samples once the direction is agreed. Most stocked items are supplied free of charge, typically within a week.

How the Collaboration Actually Runs

These projects follow a fairly consistent path:

You provide the requirement → we propose an alternative with a drawing → your team evaluates and confirms → samples are shipped or built → approval leads into production

In practice, what customers ask about most at this stage is sample and production timing. Technical questions are comparatively few. Once the specification is confirmed as correct, the discussion generally moves to lead time and unit price.

How Many Rounds Before a Sample Is Approved

In most cases, one round is enough. Connectors are standard parts with clear specification mapping, so a rebuild is rarely needed. For cables and wire harnesses, where a specification may need fine-tuning, matters usually settle within three rounds.

When a rebuild is needed, the reason is rarely the build itself. More often, the design team or end customer sees the physical part and realizes the original specification needs adjusting.

Sample Cost and Quantity

Stocked items: supplied free of charge, typically 3 to 5 pieces. That quantity reflects the actual approval process, which usually has to cover end customer review, internal review, engineering review, and fit testing. Once confirmed, stocked items generally ship within a week.

When costs apply: if the required material is not in stock and has to be purchased for the project, or the sample quantity is substantial, we set out the associated costs before proceeding.

Our preference is to supply samples free wherever possible, since a smooth introduction serves both sides. Costs only come into the conversation when material genuinely has to be sourced for the project, or when the line has to be scheduled separately for a small sample run.

A Real Case: Cosmetic Defects on a Designated LED Indicator

Passing the sample stage does not guarantee a smooth production run. Here is a situation we encountered.

On an LED indicator cable project, samples were entirely sound, but cosmetic defects began appearing once volume production started. The issue lay in the LED head structure of the designated connector: under impact or compression, it could shift inward into the connector body and sit recessed. Electrically it still functioned and the LED still lit, but the appearance no longer met specification. The rate ran to around ten or more pieces per thousand, which is high for this type of product.

The cause was not the assembly process. It came from the structural characteristics of the part itself, and in some cases had already occurred by the time the part arrived from the manufacturer. The manufacturer accepted free returns, but the disruption to the customer's production schedule remained.

The constraint in this case was clear: the part was designated by the end customer, the specification could not be changed, and no PCN route was available. With a part change off the table, our approach was:

  • 100% inspection before shipment: every piece checked for correct LED head position
  • Buffer stock: around 50 pieces held as standard for immediate replacement
  • Direct replacement for defects arising in transit or assembly: no debate over attribution, with priority on keeping the customer's line running

This is not the best technical answer, since the best answer would be changing the part, and that was outside what we could decide. Within the constraints that existed, it was the approach that kept the customer's losses lowest.

The Value of Being Involved From NPI

What this kind of collaboration delivers, above all, is time.

The design team gets a concrete proposal and drawing while the specification is still being settled, with no need to approach suppliers one by one and wait on each reply. Quotation and drawing arrive together, so evaluation and decision can happen in a single pass.

For the purchasing team, having one more concrete, comparable option on hand strengthens the basis for the decision, whichever way it finally goes.

Who This Applies To

  • The original part cannot arrive in time and an alternative needs rapid feasibility confirmation
  • The specification is still under evaluation and a physical sample would aid the judgment
  • Sample quantities are needed for several parties to review simultaneously
  • An end customer has designated a part that carries known limitations in use
  • Limited bandwidth during NPI, with a need for proposals and drawings supplied in parallel
