Preferred Supplier Update Process

Executive Summary

The Preferred Supplier Update Process is part of the Marketplace and Supplier Sourcing process wave. It defines the controlled operating step that produces this outcome: Update preferred supplier relationships based on approved performance, trust, category, customer preference, and governance review.

This is a business process specification. It does not define software implementation, API contracts, database schemas, or source fact ownership changes.

Why This Exists

This process exists because supplier and service provider sourcing must be repeatable, auditable, evidence-based, approval-aware, and connected to bid preparation, contract delivery, funding needs, and organizational preferences. Marketplace and Supplier records must remain distinct even when they support the same sourcing workflow.

Owner

The owning Practice is Supplier Marketplace. The primary Digital Professional is Nexus. The Chief Product Officer and Enterprise Architect owns the process standard. Domains retain ownership of business facts.

Business Value

This process creates business value by improving supplier discovery, quote quality, supplier selection discipline, response tracking, verification review, provider onboarding, delivery support, and long-term supplier performance learning.

Primary Boundary

Supplier owns preferred supplier state; humans approve material preferred supplier changes.

Trigger

• Performance evidence supports preferred supplier change or human request is made.
• Human request from customer CEO, bid owner, contract owner, funding owner, or delegated user.
• AIOS event orchestration from a prior Marketplace Sourcing process state.

Inputs

Input	Source Owner
Marketplace listings, provider categories, search results, matching records, quote requests, and marketplace workflow state	Marketplace Domain
Supplier profiles, relationships, verification signals, quote performance, ratings, reviews, response time, previous contracts, preferred supplier state, and performance records	Supplier Domain
Bid workspace needs, supplier inputs, pricing dependencies, tender support requirements, and proposal constraints	Bid Domain
Contract delivery needs, supplier dependencies, milestones, deliverables, risks, and performance context	Contract Domain
Funding readiness, funding partner workflows, cash-flow risk, funding assessment, and funding application state where relevant	Funding Domain
Organization profile, procurement preferences, operating regions, services, products, and business context	Organization Domain
Notification preferences, quote request reminders, provider communication delivery, escalations, and communication history	Notification Domain
KPI snapshots, sourcing trends, quote performance summaries, supplier performance summaries, and executive reports	Analytics Domain
Recommendations, confidence scores, explainability, reasoning records, and memory proposals	Intelligence Domain

Procedure

1. AIOS receives the trigger and creates or updates the process instance.
2. AIOS assembles authorized context from Marketplace, Supplier, Bid, Contract, Funding, Organization, Notification, Analytics, and Intelligence where relevant.
3. Nexus receives a scoped work packet with SOP, task objective, evidence requirements, guardrails, and deadline.
4. Nexus performs the assigned search, match, request, comparison, review, selection support, onboarding, performance capture, or feedback activity within Supplier Marketplace authority.
5. Supporting Digital Professionals contribute only where their Practice expertise is required.
6. AIOS checks missing evidence, source ownership, response deadlines, funding implications, verification risk, approval thresholds, confidence, and exception conditions.
7. High-impact sourcing outputs are routed to authorized human approvers through Ari and Ava where executive coordination is required.
8. Accepted outcomes are recorded through the owning Supplier workflow or relevant Domain workflow.
9. Notification sends quote requests, reminders, and escalations only when requested by the process or event policy.
10. Analytics captures KPI signals and sourcing performance summaries.
11. AIOS records audit evidence and proposes memory updates when approved learning is available.
