The document discusses different types of customer segmentation approaches and argues that an integrated approach is best. It describes four main types of segmentation: lifestyle, product usage, needs-based, and value-based. On a macro level, needs-based segmentation can identify broad customer segments for targeting and strategy. Value-based segmentation helps define service levels and prioritize retention efforts. Usage and lifestyle segmentations are best used on a micro level for tactics like promotions and communications. An integrated approach aligns these segmentations across the customer lifecycle for optimal marketing capabilities.
