Risk Advisory: What We Assess
Our Risk Advisory practice covers three core assessment types, each delivering concrete, actionable outcomes:
Maturity Assessment
We evaluate your RA and FM organization across four dimensions-Organisation, Process, Measurement and Technology, benchmarked against TM Forum guidelines. The output is a comprehensive report highlighting strengths, weaknesses, and a prioritized improvement roadmap. Typical engagement: 2–3 weeks
Risk & Coverage Assessment
We map your current revenue streams, build a detailed Risk Register and Risk Control Matrix, and calculate your risk and control coverage percentages identifying uncovered risks and recommending controls to close the gaps. Typical engagement: 3-4 weeks
Control Effectiveness & Efficiency Assessment Using
Subex’s proprietary in-house rating model, we assess each control against parameters including KPI breach, data sampling accuracy, and frequency compliance-identifying underperforming controls and providing fine-tuning recommendations. Typical engagement: Based on number of controls
RA to BA Transformation
From Revenue Assurance to Full Business Assurance
Revenue Assurance has traditionally focused on operational-level controls around billing, charging, and usage. Business Assurance extends this across every business process-from marketing and customer experience to financial reporting and regulatory compliance.
Subex guides operators through this transformation with a structured approach: assessing current RA readiness, mapping the gap to BA, building a comprehensive Risk Register and Control Universe, and delivering a detailed BA roadmap with timelines and priorities. The result is an organization equipped to provide assurance across all business processes-not just traditional RA use cases.
Margin Assurance
Profitability Visibility at Every Level
Unlike average-based cost models used by finance teams, Subex’s Margin Assurance practice delivers granular profitability computation at the subscriber, product, partner, and network element level – updated monthly using actual cost and revenue data.
Customer
Track margin-impacting KPIs like cost per subscriber and identify negative-margin customers to exclude from costly promotional campaigns.
Product
Classify products as obsolete, redundant, or retained, and quantify revenue leakage from negative-margin products to support effective portfolio decisions.
Partner
Validate vendor agreements and settlements to identify partners and services with negative margins, avoiding non-profitable relationships.
Network
Arrive at cell-site and network-element-level profitability using network utilization and revenue data from charging and billing systems.
Subex’s Margin Assurance practice has delivered measurable impact for operators worldwide:
- Identified negative margins of $8.8M+ across multiple products for a leading APAC operator, enabling data-driven portfolio decisions and plan rationalization.
- Helped a GCC operator reduce roaming costs by 20%, improving overall profitability through targeted Margin Assurance interventions.
Migration Assurance
Protecting Revenue Through Every Phase of Migration
BSS/OSS migrations are among the highest-risk activities a telecom operator can undertake. Subex works as extended RA team and provides independent assurance across all three phases to protect revenue, ensure data integrity, and support confident Go/No-Go decisions.
Subex has delivered Migration Assurance for Tier 1 operators in Australia ($15M leakage identified), Singapore ($2M leakage identified), and Kuwait-covering prepaid, postpaid, and enterprise segments.
Pre-Migration
Strategy validation, reference data review, dry run scheduling, readiness validation, and system and product configuration checks.
During Migration
Business assurance tests, configuration validations, go-live validations, rollback strategy review, and reporting validations.
Post-Migration
Pre/post migration reporting, new Risk Control Matrix, updated SOPs, customer experience validation, and upstream / downstream system integration checks.
