The Art of Convergence: A Framework for True Convergence in Telecom BSS

Convergence-the architectural unification of distinct telecommunications platforms into a coherent, scalable, and operationally unified ecosystem-has been a defining objective of the global BSS industry for over a decade. Yet despite sustained investment and widespread market rhetoric, genuine convergence remains elusive for most vendors and operators. This paper argues that the gap between claimed and achieved convergence is fundamentally an architectural and organisational failure, not a technology limitation. Drawing on firsthand experience leading large-scale convergence programmes at Huawei and Broadcom from 2015, and on earlier strategic consulting disciplines developed at Arthur Andersen (later Accenture), this paper examines what true convergence requires architecturally, contrasts it with cosmetic integration patterns prevalent in the industry, and introduces an original Convergence Maturity Model across five defined stages.
