From Local Practices to a Minimum Common Standard: A Modular, Phased Framework for Supplier Evaluation Harmonization

Supplier evaluation is often approached as a scoring problem, while many deployments fail due to lack of

harmonization across sites, entities and evolving external constraints. This paper proposes a framework to harmonize

supplier evaluation through a minimum common standard and modular extensions.

Design/methodology/approach – Conceptual synthesis of recurring implementation challenges in multisite and

turbulent contexts. The framework defines a Minimum Common Standard (process, data, evidence, rules, governance),

a modular architecture to absorb local variability and new external requirements, and a five-phase rollout model. Three

structured vignettes (Create/Extend/Transform) illustrate applicability. Meta-performance indicators and failure modes

are proposed.

Findings – The framework specifies what must be standardized to ensure comparability, auditability and actionability

(and what should remain configurable). It separates internal harmonization (cross-entity comparability) from external

harmonization (integration of new standards/regulations/constraints via modules), and provides a phased rollout logic

to reduce adoption risk.

Originality – The paper reframes supplier evaluation from “how to score suppliers” to “how to harmonize an

evaluation system under organizational and external turbulence”, introducing a Minimum Common Standard and

modular governance as a deployable blueprint.

Keywords – supplier evaluation; harmonization; minimum common standard; modularity; governance; phased

implementation.

Paper type – Conceptual paper.
