How to Tier and Manage Suppliers Effectively Across Their Full Lifecycle

Why Tier Supplier Management?

Supplier tiering is not just labeling; it enables differentiated strategies such as priority engagement for critical suppliers, standardized control for ordinary ones, and restricted ordering for marginal suppliers.

Common Classification Models

Model 1 – By Cooperation Relationship

Potential Supplier : No cooperation yet, only basic contact.

Qualified Supplier : Passed admission, has transaction history.

Core Supplier : Stable supply, high collaboration, strong delivery capability.

Strategic Supplier : Deeply integrated, participates in R&D, co‑building, or investment.

Model 2 – Kraljic (Material Importance & Supply Risk)

Critical Supplier : Provides irreplaceable, high‑impact materials; high risk, must be closely monitored.

Strategic Supplier : Offers resources that support long‑term strategy, such as technology cooperation.

Leverage Supplier : Standardized items with many alternatives; suitable for price negotiation.

Routine Supplier : Easily replaceable, low impact; processes can be simplified.

Model 3 – By Performance Rating

Level 1 : Outstanding performance, priority cultivation.

Level 2 : Stable cooperation, regular follow‑up.

Level 3 : Occasional issues, monitor usage.

Level 4 : Frequent anomalies, restrict ordering.

Supplier Lifecycle Management (DMAIC)

D – Define : Identify needed suppliers, resources, and stakeholder responsibilities.

M – Measure : Collect supplier data, set standards, and select qualified suppliers.

A – Analyze : Monitor and diagnose supplier issues.

I – Improve : Develop improvement plans and assist suppliers.

C – Control : Ensure improvements are sustained.

The lifecycle progresses through six stages: External → Potential → Qualified → Cooperation → Tiered → Eliminate.

Key Process Stages

1. Supplier Information Management : Collect basic company data, auto‑fetch business registration info from third‑party platforms, and store structured records for future reviews.

2. Procurement Quotation Management : Use standardized quotation templates, send invitations, collect online quotes, and automatically generate comparison lists.

3. Procurement Execution Management : Complete order issuance to contract signing online, generate electronic orders, and synchronize delivery, receipt, and quality inspection data.

4. Reconciliation / Invoice / Payment Management : Automatically aggregate transaction data, generate real‑time statements, invoices, and payment status, with system‑driven approval workflows.
