The document discusses the development of marketing management school of thought from the 1950s to 2000s. It analyzes criticisms of the school from the time periods it was developed, the data used, questions addressed, and theories/concepts. While marketing management focuses on how organizations market products/services from the seller's perspective, it is criticized for not addressing other questions, using only micro-level data missing general perspectives, and theories that varied periodically without a unified structure. Overall, the school provided an important foundation but its assumptions are outdated given changes over the past 50+ years.
