Project Overview

Project Overview

Client Background

The client is an international buyer holding supplier quotations for an electronic product, seeking greater visibility into cost before committing to production. Details confidential.

Business Requirements

Understand the product’s cost drivers, compare suppliers on a like-for-like basis, and identify qualified alternatives without compromising requirements.

Project Objective

Replace price-only comparison with a structured cost analysis that supports informed sourcing decisions.

The Challenge

The Challenge

The client held supplier quotations but lacked a clear view of how the product’s cost was actually built. A quotation is a single number; it does not explain which components drive cost, where alternatives exist, or how different suppliers compare on the same specification. Without that visibility, sourcing decisions were based on price alone, and opportunities to improve cost or reduce risk were easy to miss.

  • Quotations gave a single number with no cost breakdown.
  • It was unclear which components drove cost.
  • Alternative components and suppliers were not evaluated.
  • Like-for-like supplier comparison was not possible.
  • Sourcing decisions risked being based on price alone.
Our Approach

Our Approach

How Phenom Sourcing approached this project — from understanding requirements through controlled delivery.

1

Understand

Reviewed the product specification, target cost and the quotations the client already held.

2

Evaluate

Broke the product into cost-driving elements (BOM, components, process) and screened supplier options.

3

Develop

Built a transparent cost picture and proposed qualified alternatives where sound.

4

Control

Compared suppliers on a like-for-like basis so the decision was documented and repeatable.

What We Did

What We Did

1

BOM Breakdown

Mapped the full bill of materials, identifying every component and cost driver.

2

Component Review

Reviewed components for specification, pricing and availability, proposing alternatives where sound.

3

Cost Analysis

Built a transparent cost picture rather than negotiating the quoted price directly.

4

Alternative Sourcing

Identified qualified alternative components and suppliers to widen options.

5

Supplier Comparison

Evaluated suppliers on capability, price and reliability for a clearer decision.

Manufacturing / Technical Focus

Manufacturing & Technical Focus

BOM Structure

Full component and sub-assembly mapping.

Component Cost

Per-component cost visibility.

Alternative Components

Qualified substitute options reviewed.

Supplier Comparison

Like-for-like quotation comparison.

Value Engineering

Cost drivers addressed through design and sourcing.

Cost Transparency

A clear basis for sourcing decisions.

Quality & Risk Control

Final Verification
Confirmed before shipment

Where samples were involved, quality checks were aligned with the agreed specification so that lower cost did not come at the expense of conformance. Cost optimization was treated as a structure review, not a price-only negotiation.
