4.9 Chapter Summary & Review
Summary
This chapter discusses the importance of product and service design as a driver of competitive advantage. It introduces the new product development (NPD) process, which includes idea generation, idea screening, concept testing, market strategy development, business and financial analysis, test marketing, and commercialization. Each step is intended to ensure that products align with customer expectations, are technically and financially feasible, and achieve market success. The chapter also highlights the House of Quality (HOQ) as a tool to translate customer requirements into technical features, ensuring customer-centred design and effective cross-functional collaboration.
The chapter further examines the product life cycle (PLC)—introduction, growth, maturity, and decline—outlining the strategic implications of each stage for sales, profitability, and competition. It stresses the importance of Life Cycle Cost (LCC) analysis, which evaluates total ownership costs from R&D through end-of-life, enabling firms to make informed design, pricing, and sustainability decisions. Concepts such as Total Acquisition Cost (TAC) and Total Ownership Cost (TOC) are introduced to help firms balance short-term and long-term financial considerations. Through frameworks, examples, and case studies, the chapter demonstrates how integrating customer needs, cost analysis, and strategic planning leads to innovative, sustainable, and competitive products.
