Customer Case Study · Supplier Evaluation Matrix
The AC manufacturer builds room air conditioners and their components at scale, with hundreds of suppliers behind every unit. HMC built a supplier evaluation workspace for the procurement team: a weighted scoring matrix the category heads agree on, a 3D view of component risk, supplier segmentation, a volume split optimiser, a disruption simulator, and GenAI that reads and compares quotes.
Figures indicative; validated metrics available on request.
Quality lived in the QMS, delivery in the ERP, prices in emails and spreadsheets. Supplier reviews were long, subjective and hard to compare across categories.
Defect rates, on-time delivery, prices and certificates sat in different systems and files.
Rankings depended on who was in the room; criteria and weights changed from review to review.
Critical parts depended on one supplier or one country, with little view of the exposure.
Different currencies, Incoterms and payment terms made true landed cost slow to work out.
A transparent method the category heads sign off, applied the same way to every supplier.

A synthetic supplier base for a 1.5-ton inverter split AC: 8 component families, 12 anonymised suppliers across India, China, Thailand and Vietnam. Everything below is live: change the weights and every module updates.
Optional. Every ✦ button already works on built-in templates. Add an OpenAI key to read any quote you paste, ask the supplier base anything and have AI write review letters.
The key goes only from this browser to OpenAI and stays in memory unless you tick "remember". Only the synthetic data on this page is sent.
An exploded split AC, every component family coloured by supply risk. Drag to rotate, scroll to zoom, click a part (or pick it from the list) to see who supplies it.
Simplified 3D model for illustration. Risk = single-sourcing, import share, supplier scores, lead time and criticality.
Twelve suppliers on eight criteria, each scored 0–100 from raw metrics. Set weights with sliders or presets, or switch to pairwise comparison (AHP) the way a sourcing committee would. Rows re-rank live.
Each supplier placed by weighted performance and business impact. Play the quarters to watch suppliers move as improvement plans land. Click a supplier for its 360 card.
Pick a component. The optimiser splits annual volume across qualified suppliers by landed cost, cost of poor quality and supply risk, within capacity, and keeps a minimum share with a second source.
Effective cost per unit = landed price + cost of poor quality (defects per million × 40 × price) + a supply-risk premium scaled by the resilience setting.
Trigger an event and see which suppliers and parts are hit, whether inventory covers the gap, the cost impact and the recommended switch.
Compare quotes in any format on true landed cost, draft a quarterly review letter from the scorecard, or ask the supplier base a question in plain English.
Landed cost assumes USD ₹84, EUR ₹91, CNY ₹11.6, THB ₹2.45, sea freight ₹120 per unit from FOB ports, insurance 0.5%, import duty 10% on CIF, inland freight ₹40, and 10% a year cost of money for payment terms. Illustrative only.

Synthetic quotes and suppliers. Template mode reads the sample formats; with a key, the AI reads any quote text. Buyers verify every extracted value.
Scorecards and improvement plans narrowed the spread of defect rates, and second sources closed most of the single-source gaps.

When the committee signs the weights first, the ranking is accepted, not argued.
The cheapest quote on paper is often not the cheapest at the plant gate.
Know the cover days and the switch before the disruption, not after.
