RESEARCH METHODOLOGY 2.2.2 TOP-DOWN APPROACH • In the top-down approach, the overall market size was used to estimate the size of individual markets (mentioned in the market segmentation) through percentage splits from secondary and primary research. For the calculation of specific human insulin market segments, the most appropriate immediate parent market size was used to implement the top-down approach. The bottom-up approach was also implemented for data extracted from secondary research to validate the market segment revenues obtained. • Market shares were then estimated for each company to verify the revenue shares used earlier in the bottom-up approach for data validation. With the data triangulation procedure and validation of data through primaries, the overall parent market size and each individual market size were determined and confirmed in this study. The data triangulation procedure used for this study is explained in the next section. • FIGURE 3 TOP-DOWN APPROACH •   • [email protected] www.marketsandmarkets.com 9
