STEM applications and examples

Quick and easy business-case evaluation

In today’s constantly changing technology environment, there is a real business imperative to perform rapid and reliable evaluations of new service concepts, and to be able to readily adapt such business cases to changing market conditions and emerging vendor solutions.

STEM (Strategic Telecoms Evaluation Model) provides a robust and efficient platform for creating business and investment plans which embrace alternative market, technical and economic futures. You can focus on the network configuration and business dynamics while STEM manages the integrity of the underlying calculations.

Business-case evaluation modelling process

Broadband Internet with voice option on ADSL

A competitive operator offers a selection of ADSL packages to the residential and small business markets. In how many exchanges should the operator co-locate equipment? What will be the economic impact of offering an analogue voice service in conjunction with broadband Internet access using an ADSL line?

Network configuration assumption

STEM presents the technological options in a clear and consistent framework and delivers standard GAAP financials and hundreds of built-in results through an integrated charting interface which allows you to drill-down into individual elements and the separate components of revenue and cost.

Service alternatives and business results

High-bandwidth mobility services and HSDPA

Operators are considering upgrading their basic 3G networks to support new services such as mobile TV/video and high-speed Internet access, and must determine the business case for the required network enhancements to support them, for example through HSDPA (high-speed downlink packet access).

A major vendor of HSDPA technology has used STEM to develop a comprehensive financial modelling tool, both for its HSDPA business unit and for account managers communicating directly with operators worldwide.

The model depicts an operator’s current (R99) network and the introduction over ten years of higher bandwidth services. Forecast demand is met firstly through existing R99 resource capacities and then through the deployment of new HSDPA resources. The introduction of these services has an impact on the operator’s core and radio networks, as well as transmission link requirements, IP transport infrastructure, and IP peering costs. The model includes resource lifecycle costs, price depreciation over time and existing R99 roll-out plans.

Established modelling process

Business-case models are commonly built the hard way, from the bottom up each time in a spreadsheet. As well as the laborious re-working of basic calculations, editing at the cell level inevitably leads to subtle copy errors which may only be detected by a time-consuming review process. Arbitrary modelling techniques and a lack of high-level structure guarantee slow handover as colleagues must comprehend the business logic cell-by-cell.

STEM wraps up core elements of telecoms business planning, enabling rapid and reliable, same-day development of business cases. Consistent structure and graphics provide a common language across divisional teams. Decision makers have greater confidence in models built on a reliable, standardised business-modelling platform.
