Few organisations take the idea of learning as seriously as the military. They will take their best people out of work for a year (or 3 or 5) to study. They will produce endless briefings before acting, and endless paperwork reviewing what occurred. This all makes sense when the stakes for failing to learn can literally be death, or at best failing at your job and extending a long conflict. For all that importance, being a learning organisation is hard. Really hard.
Across four case studies (US Navy in WW2, US Air Force in Korea, US Army in Vietnam, US Marines in Iraq), Hoffman shows how difficult that challenge is in war. All of these services had distinct cultures and leaders, and yet even the best of them took at least 18-24 months to go from some bright platoon leader having an idea, to an organisation which had adopted wholesale that idea.
The field of military innovations has blossomed over the past decade, and Hoffman's Mars Adapting provides a useful one-stop overview of the field. He writes engagingly in explaining how past scholars have tried to explain innovation (Does it come from external pressure such as a new adversary, does it only work when particular institutional arrangements are in place, such as the right leaders, the new fresh-thinking generation or the right kind of competition for resources?). He contributes to this by adapting Organisational Learning Theory (OLT) from the Business literature. This highlights four themes, Leadership, Organisational Culture, Learning Mechanisms and Dissemination Mechanisms. Each is crucial and provides a useful set of signposts to pull apart these complex case studies (most covering many years, actors, settings and technologies) into coherent assessments of how well they learned and adapted.
Though the focus is on the military and particularly war time adaption, I could see many applications of OLT to peacetime organisations. Indeed I'd picked up this book partly on the strength of the author and hoping to better understand the organisations he described, but came away impressed by the theoretical foundations and its utility.
