Market understanding refers to an approach in product management in which different stakeholders (such as product managers, developers, marketing teams, customers and others) work together in cross-functional teams to ensure that the product meets user needs, remains competitive and is successfully brought to market.
According to Clayton Christensen, around 95 % of new products fail due to a lack market understanding. Market segmentation is an approach to divide a broad target market into smaller, more homogeneous segments that have similar needs, desires or characteristics in order to better target marketing strategies and product development. Market segmentation offers many opportunities to identify patterns in a market. Segmentation can be used in all phases of product development, from strategic to technical issues.
