Design to Cost (DTC): How Procurement and Engineering Cut Cost Without Cutting Corners

Design to Cost procurement helps manufacturing businesses reduce the cost to buy by removing unnecessary cost from design. By reviewing drawing packs, materials, tolerances and manufacturing routes with engineers, you can lower the cost to manufacture, and secure better, more sustainable pricing from the supply market.

Design to Cost (DTC) flips that. It brings cost thinking upstream into design and specification, so the final product is easier to make, easier to source, and cheaper to buy, without compromising performance, compliance, or quality.

At Pro Outsourcing, we support manufacturing companies and organisations that buy manufactured items by working alongside engineering teams, using drawing packs and BOMs as the starting point, not the finish line.

What Design to Cost actually means

DTC is a structured way to reduce total cost by reviewing:

• How the item is made (process route, tolerances, finishing, assembly steps)

• What it is made from (material choices, grades, coatings, availability)

• How it is specified (unnecessary tight tolerances, over-specification, legacy standards)

• How it is sourced (supplier capability, geography, tooling strategy, volumes, MOQ)

This is not about “cheapening” a product. It’s about removing cost that does not add value.

Where Pro Outsourcing fits

Engineering knows performance, compliance, and function. Procurement knows market capability, supplier economics, risk, and commercial levers.

We sit in the middle, translating design intent into cost-effective sourcing options. Think of us as the people who can read a drawing pack and still ask the awkward question: “Is that tolerance doing any real work, or is it just expensive nostalgia?”

What we review (the practical stuff)

Working with your engineers and stakeholders, we typically review:

1) Drawing packs and tolerancing

• Identify tolerances that drive high-cost machining or inspection
• Review surface finishes that increase cycle time or scrap risk
• Challenge “gold plated” specs where a standard is enough

2) Materials and grades

• Alternative grades with equivalent performance
• More available materials that reduce lead time and price volatility
• Coatings and treatments that meet the requirement with lower processing cost

3) Process route and manufacturability

• Machine versus fabricate versus cast versus mould
• DFM suggestions that remove operations (setups, welds, fasteners, inspection points)
• Batch optimisation and tooling strategy

4) Supply market options

• Identify suppliers who are better suited to the process and tolerances
• Dual-source strategies for resilience
• Country of origin considerations and trade-offs on logistics, duty, and lead time

5) Total cost to buy
Not just unit price. We assess:

• MOQ and inventory burden
• Quality costs and inspection effort
• Freight, packaging, and handling
• Warranty, field failure risk, and serviceability

Typical DTC opportunities we see

Every business is different, but common wins include:

• Replacing exotic materials with standard grades where performance allows
• Relaxing a tolerance that forces grinding, CMM inspection, or slow machining
• Swapping a machined part for a fabricated assembly (or vice versa)
• Reducing part count and assembly time
• Changing finishing processes to remove cost and improve throughput
• Rationalising supplier base to match capability to requirement

How the engagement works

We keep it simple and engineer-friendly:

1. Kick-off and data request
   You share drawing packs, BOMs, annual volumes, and known issues.
2. Cost driver assessment
   We map the top cost drivers: materials, processes, tolerances, and supply risk.
3. Options and recommendations
   We provide a short report with practical alternatives, pros and cons, and expected savings ranges.
4. Supplier validation
   We test the options with the market, validate feasibility, and support RFQs.
5. Implementation support
   Engineering change support, PPAP or equivalent alignment where needed, contract and pricing.
