The Cisco VNI Service Adoption Forecast Methodology explains the rationale and process behind the projections. It details how the research team developed total addressable market projections for each service segment, including residential, consumer mobile, and business.
View the images below to learn how the Cisco VNI SA research team developed total addressable market (TAM) projections for each service segment (residential, consumer mobile, and business). This analysis provides the primary basis for the service adoption forecast.
VNI Service Adoption Research Methodology
Cisco follows a rigorous methodology to forecast the global and regional adoption of 24 services across three different categories: residential, consumer mobile, and business. The VNI Service Adoption Forecast makes use of several primary data sources: publicly available data from international and national institutions and government bodies and third-party research and survey data from independent research firms.
To analyze the available data, and forecast future adoption rates, Cisco researchers have applied extensive data modeling techniques.
Together, supply side data such as shipments of technology products and demand side data such as user adoption and preference are applied to provide meaningful insights into future adoption rates.
Each forecast is calculated based upon the Compound Annual Growth Rate (CAGR) or the year-over-year growth rate over a 5-year period. This calculation yields an estimate of how users/subscribers, devices/connections and specific service adoption rates will grow or decline over the forecast period.
