The assignment discusses the importance of marketing and sales in practice, focusing on understanding customer needs through market segmentation, targeting specific markets (B2B and Consumer), and measuring financial return using gross margin and return on investment. The concept of the Pareto principle is applied to target 20% of customers for 80% of success. New products or services are also discussed as a way to stay ahead in competition, along with monitoring marketing activities and trends. Finally, the value of marketing is measured by comparing results with identified targets using a balanced scorecard.
