Methodology
We implement a mix of primary and secondary research for our market estimate and forecast. Secondary research forms the initial phase of our report, where we conduct extensive data mining, referring to verified data sources such as independent studies, government and regulatory published materials, technical journals, trade magazines paid data sources such as Hoover’s, Factiva, ICIS, and so on. This forms the basis of our estimates. For forecasting, the following parameters are considered:
• Market drivers and restraints, along with their current and expected impact
• Regulatory scenario and expected developments
We assign weights to these parameters and quantify their market impact using weighted average analysis, to derive an expected market growth rate. Further, we use correlation, regression and time-series analysis to evaluate key industry dynamics. All our estimates and forecasts are verified through exhaustive primary research with Key Industry Participants (KIPs) which typically include:
• Market-leading participants
•技术分销商和供应商
• Key consumers and clients
These exhaustive primary interviews help our analysts in validating market and segment estimates and forecast. Additionally, we also gain significant industry insights, key developments and expectations. Grand View Research only utilizes validated and authenticated secondary data sources. Some of the secondary sources used for this report include but are not limited to:
• International Telecommunications Union
• Internet Telephony Services Provider’s Association
• The Voice over IP Security Alliance (VOIPSA)
