Successful companies in high-growth markets excel in three areas: sizing the future by accurately assessing market opportunities across time horizons; shaping the future by cultivating new demand; and seizing the future through operational agility. To develop these capabilities, companies should conduct global demand forecasting, experiment with new customer segments, build local partnerships, innovate to meet unmet needs, and develop agile operations. This will allow companies to open new windows of opportunity in emerging markets and compete effectively for future growth.
