The capability to provide value adding services in the Customer's Acti
vity Cycle is the key differentiator for firms today. This, asserts th
e author, is because value as seen by customers is meaningful only in
terms of what customers get out of core products and services, not jus
t what goes in (as was the case previously), With this switch in empha
sis-from the quality of the products and services to the quality of th
e result for customers-managers have to rethink what and how they meas
ure their performance in the marketplace. With so much dependent on 's
oft' services and behaviours they have to adjust both what they measur
e and how. The author provides a framework for achieving this.
