Product & Design

Bill of materials cost modelling support

Build an indicative cost model for a new product from its bill of materials, using historic component prices, supplier quotes, and current material indices, and flag where a design choice is driving cost.

Opportunity assessment

Business Impact
3

Moderate impact. Meaningful cost or revenue improvement, likely noticeable at function level but modest relative to total business scale.

Feasibility
3

Moderate effort. Requires configuration, prompt engineering, and testing. A capable team can get there but expect several months.

Data Readiness
2

Demanding data requirements. Relies on clean, integrated data across multiple systems. Significant data preparation work typically needed.

Risk Exposure
4

Low risk. Limited external exposure. A human reviews output before it reaches anyone outside the team.

Change Complexity
3

Moderate people impact. Part of someone's working day changes. Requires training and some adjustment time, but roles remain broadly the same.

Things to consider

  • The commercial value is in showing the cost consequence of a design decision while the decision is still reversible. A cost model produced after the tech pack is signed off is an accounting exercise, not a lever.

  • Historic component pricing goes stale quickly in volatile material markets. Blend your own paid prices with a published index and be explicit in the output about which components are estimated rather than quoted.

  • Do not let the model become the negotiation position. Use it to identify which lines are worth challenging, then negotiate on evidence.

  • Experiment starter: Rebuild the cost model for twenty products you have already bought and compare the modelled cost against the price you actually paid. If the model is within 8% on three quarters of them, use it at design stage on the next range.
