PMTK Problem Echelon Model
Developed by Blackblot, the PMTK Problem Echelon Model is a descriptive model that demonstrates the inner workings of value-chains and helps to map the various problems handled by the industry and the market.
This model serves several objectives: structure and simplify the analysis of market problems in product management, explain how technology finds uses and applications, and demonstrate the sequence of events in which market dynamics generate market problems which are then followed by products and technology that solve them.
