I've begun reading Etienne Wenger's Communities of Practice: Learning, Meaning, and Identity.
I ran into this book while reading John Seely Brown and Paul Duguid's Social Life of Information, about which I've written here earlier. I've always been interested in how social groupings and organizations learn, evolve, prosper and survive, how we learn and work, and how we come to be who we are as individuals.
Wenger's book would be a good start for whoever wants to explore these topics. Wenger is also deeply interested in building the conceptual framework that will help with the design of organizations, artifacts and processes.
Wenger's ambitious enterprise suits the practitioner as much as it stimulates the theoretician. As the book plate says, the material "is presented with all the breadth, depth, and rigor necessary to address such a complex and yet profoundly human topic."
