Original job description

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.

Required Skills & Experience

8+ years in Telecommunications, BSS/OSS, Enterprise Architecture, or Solution Architecture.
Strong hands-on PSR / Product-Service-Resource modeling experience.
Strong knowledge of TM Forum ODA and eTOM.
Hands-on experience with TM Forum Open APIs, particularly:
TMF620, 622, 633, 640, 641, 642, 645, 648, 651, 652.
Experience with Product, Service, and Resource Catalogs.
Strong experience in product/order decomposition and fulfillment orchestration.
Understanding of CPQ, CRM, Order Management, Service Management, Resource Management, Billing, and Assurance.
Experience defining PSR relationships, cardinality, characteristics, dependencies, and decomposition rules.
Strong understanding of CFS, RFS, and Resource models.
Experience producing Enterprise Architecture, Application Integration, Sequence, Communication, and Process diagrams.
Experience with Current-State / Future-State architecture and FMO/TOM initiatives.
Experience with Install Base, Configuration Items, alarms, incidents, and operational correlation.
Strong stakeholder-management and communication skills.

Experience with TM Forum SID / Information Framework.
Experience with ODA Value Streams and Business Architecture.
Experience establishing or operating PSR governance frameworks.
Experience onboarding multiple product families into a common PSR model.
