Communications Service Providers (CSPs) are no longer just telcos; they’re becoming tech-cos. However, modernizing BSS/OSS systems is no longer a checkbox but a strategic leap. The real dilemma is whether to build custom platforms for control and differentiation or buy off-the-shelf solutions for speed and scale. This whitepaper helps you answer that question.

Backed by industry standards and field-proven frameworks, this guide offers a practical roadmap to drive high-impact transformation without the guesswork. You’ll explore TM Forum-aligned methodologies that ensure CSPs like yours can modernize confidently, balance short-term needs with long-term goals, and avoid the costly pitfalls of misaligned tech investments.
