Finance ✦ Penny’s Take
Organization Development and Change
Thomas G. Cummings · 2005
76/100
👍 Worth It
Cummings and Worley built the market-leading OD textbook for good reason: it covers the full cycle of organizational development practice from diagnosis through evaluation, balancing behavioral science theory with frameworks practitioners can actually use. The 8th edition is now two decades old and some models have been refined in later editions, but the foundational thinking holds up. If you are an HR professional, OD practitioner, or MBA student, this belongs on your shelf — just be aware you are working from a 2005 snapshot.
