PSR Enterprise Architect – TM Forum / eTOM

Role Overview

We are seeking a PSR Enterprise Architect / TM Forum Architect to design, govern, and validate the end-to-end Product-Service-Resource (PSR) catalog model across the customer journey from Day -1 through Day 2 , covering Buy, Get, Pay, and Support .

The role will partner with CUSTOMER Enterprise Architecture as a Future Mode of Operations (FMO) advisor , ensuring PSR and solution designs align with target Business, Data, Application, Integration, and Process Architecture .

The ideal candidate will have strong telecommunications architecture experience with TM Forum ODA, eTOM, Open APIs, PSR modeling, catalog governance, CPQ, order decomposition, fulfillment, billing, and assurance .

Key Responsibilities

PSR Architecture & Governance

- Design and govern the end-to-end PO → PS → CFS → RFS → RS model for each product family.
- Define and enforce relationship types, cardinality, characteristics, dependencies, lifecycle, and decomposition rules .
- Validate catalog structural integrity in a governed authoring environment before publication.
- Apply approved PSR Governance Best Practices and Mandatory vs. Optional characteristic methodology consistently across Day 0 and Day 1.
- Ensure product, commercial, pricing, packaging, service, platform, infrastructure, and resource-owner inputs are reconciled into a single PSR blueprint .

Day 0 – Buy / Quote-to-Order
- Define PO/PS commercial and technical characteristics exposed to CPQ for guided selling, pricing, configuration, and qualification.
- Design real-time service qualification and quote flows using:
- TMF620 – Product Catalog
- TMF645 – Service Qualification
- TMF648 – Quote Management
- TMF651 – Agreement Management
- Define commercial characteristics that provide a common source for pricing, order decomposition, fulfillment, and billing .
- Validate Day 0 processes, data, and operations against PSR governance standards.

Day 1 – Get / Order-to-Fulfillment
- Define how a signed Product Order decomposes into Service Orders and Resource Orders .
- Define CFS/RFS/RS decomposition , build-sequence dependencies, and fulfillment rules.
- Align orchestration with:
- TMF622 – Product Ordering
- TMF641 – Service Ordering
- TMF640 – Service Activation & Configuration
- TMF652 – Resource Order Management
- Ensure commercial characteristics used during Buy remain available as the source for decomposition and billing .
- Validate Day 1 processes, data, and operations against the approved PSR model.

Day 1 → Day 2 Reconciliation




- Define the reconciliation gate linking the contracted line item to the corresponding Install Base Item / Configuration Item (CI) .
- Ensure required identifiers and relationships support Alarm, Incident, and Case correlation .
- Align Day 0/Day 1 data with existing Day 2 assurance architecture.

TM Forum & eTOM Alignment
- Cross-reference PSR additions against:
- TMF620, TMF622, TMF633, TMF640, TMF641, TMF642, TMF645, TMF648, TMF651, TMF652 .
- Map processes to TM Forum eTOM Level 2/3 across:
- CRM
- SM&O;
- RM&O;
- Extend the existing TM Forum ODA Value Stream Framework and Business Architecture for Day 0 and Day 1.
- Maintain traceability:

Business Capability → Value Stream → eTOM Process → Application → API → Data → PSR Application & Integration Architecture

- Extend the existing 39-component runtime artifact inventory for Day 0 and Day 1.
- Trace each component to its:
- Governing API
- PSR layer
- Interface
- Data object
- Business record produced
- Cover key records including:
- Quote, Agreement, Customer Order, Product Order, Service Order, Resource Order, Install Base Item, Configuration Item .
- Define Application Component integration architecture for:
- Day -1 Catalog Authoring
- Day 0 Buy
- Day 1 Get
- Day 2 dependencies

Process & Interaction Architecture
- Produce current-state and future-state swimlane process flows for Buy, Get, Pay, and Support.
- Create component interaction, communication, and API sequence diagrams .
- Clearly identify:
- Trigger/event
- Source application
- Target application
- API/interface
- Data exchanged
- Record created/updated
- Downstream dependency
- Demonstrate replacement of manual processes with automated API/data triggers.

Examples: Buy: Manual address lookup → TMF645 real-time qualification

Pay: Manual invoice entry → activation event → automated billing trigger

- Feed architecture outputs into CUSTOMER's CMO → FMO Capability documentation .

Product Family Onboarding
- Lead PSR onboarding for new product families.
- Reconcile inputs from Product, Commercial, Pricing, CPQ, Service, Resource, Platform, and Infrastructure teams.
- Ensure every product family passes governance validation for:
- relationships, cardinality,



characteristics, Mandatory/Optional classification, dependencies, and decomposition .
- Extend the existing PSR Primer and Governance Guide with onboarding material for Day 0 and Day 1 Product Owners.
