Long bars -sales volume-stand for customer with a relative lower unit profit as their neighbors. Often these are the one with a purchasing power causing the weak customer profitability seen in the green segment!

The underlying Enterprise Model is made with randomly generated data for 50 people, manufacturing 15 products, sold to 264 customer.

Whale Curve  RBM uses is based upon a 2 axes diagram.

Left y-axes shows Volume and right y-axes shows Cume of Profit
