How do supporters of organizational development (OD) respond to the claim that their field offers managers nothing new?

A) Critics are unaware of OD's benefits.
B) The critics are jealous.
C) OD is part of the strategic planning process.
D) Critics are stuck in a rut and are resistant to change.
E) OD gives managers a systematic approach.

Supporters of OD would argue that their field offers managers a systematic approach to improving organizational effectiveness, which is not necessarily a new concept, but one that is based on empirical research and established theories of organizational behavior. By providing managers with tools and techniques to diagnose and solve problems in their organizations, OD can help them to navigate complex and changing business environments, which is something that traditional management theories may not address as effectively. Therefore, the claim that OD offers managers nothing new is not entirely accurate, as it overlooks the unique contributions that the field can make to organizational development and success.
