Market Size Estimation and Data Triangulation
Bottom-Up Approach
The bottom-up approach involved aggregating segment-level data, such as:
- Company revenues
- Product-level sales
- Installed base/usage volumes
- Adoption and penetration rates
- Pricing analysis
This method was primarily used when detailed micro-level market data were available.
Top-Down Approach
The top-down approach used macro-level indicators:
- Parent market benchmarks
- Global/regional industry trends
- Economic indicators (GDP, demographics, spending patterns)
- Penetration and usage ratios
This approach was used for segments where granular data were limited or inconsistent.
Hybrid Triangulation Approach
To ensure accuracy, a triangulated hybrid model was used. This included:
- Reconciling top-down and bottom-up estimates
- Cross-checking revenues, volumes, and pricing assumptions
- Incorporating expert insights to validate segment splits and adoption rates
This multi-angle validation yielded the final market size.
Forecasting Framework and Scenario Modelling
Market forecasts were developed using a combination of time-series modelling, adoption curve analysis, and driver-based forecasting tools.
Forecasting Methods
- Time-series modelling
- S-curve and diffusion models (for emerging technologies)
- Driver-based forecasting (GDP, disposable income, adoption rates, regulatory changes)
- Price elasticity models
- Market maturity and lifecycle-based projections
Scenario Analysis
Given inherent uncertainties, three scenarios were constructed:
- Base-Case Scenario: Expected trajectory under current conditions
- Optimistic Scenario: High adoption, favourable regulation, strong economic tailwinds
- Conservative Scenario: Slow adoption, regulatory delays, economic constraints
Sensitivity testing was conducted on key variables, including pricing, demand elasticity, and regional adoption.
