Market Segmentation: Foundation, Framework & Future

In this in-depth paper, Professor Malcolm McDonald explores the full journey of market segmentation — from its academic roots through to real-world implementation and the future of strategic marketing. Written in three parts, this guide examines the evolution of segmentation theory, common pitfalls, and the step-by-step process of building segmentation models that actually work in practice.

Why It Matters

  • Despite decades of theory, most segmentation projects still fail in execution
  • Market segmentation is fundamental to strategic planning and competitive advantage
  • The absence of effective segmentation leads to price wars, commoditisation, and poor ROI

Key Topics Covered

  • A brief history of segmentation research and frameworks
  • The difference between customers vs. consumers — and why it matters
  • Why demographic and geographic segmentation are often misleading
  • Micro-segments, critical purchase influences, and needs-based clustering
  • Market mapping as a tool to uncover influence points in the buying process
  • A 5-step process to develop strategic market segmentation:
    1. Define the market and build a market map
    2. Identify what is bought, where, when, and how
    3. Profile who buys using relevant descriptors
    4. Understand why people buy (benefits sought)
    5. Group buyers with similar needs into actionable segments
