I am a big fan of Gary Hamel (one of the 'big thinkers' I track). His book of a few years ago, "The Future of Management" left quite an impression on me. Excerpts can be found, starting with part 1, at: http://shoptalkmarketing.blogspot.com/2007/10/on-gary-hamels-future-of-management.html. He also has excellent views on innovation, again excerpts at https://www.mckinseyquarterly.com/Innovative_management_A_conversation_between_Gary_Hamel_and_Lowell_Bryan_2065. Note that I think he has an excellent perspective on how management will likely have to change for the future.
Hamel is one of the key forces behind the Management 2.0 Challenge (co-sponsorted by Harvard Business Review and McKinsey & Company), which started in May 2011. The HBR/McKinsey M-Prize will unfold over the course of a year and include three separate phases designed to surface the best practices and thinking around leveraging technology, reinventing strategy, and rethinking organizations. As Hamel states, "...over the next few years the emerging “social technologies” of Web 2.0 are likely to transform the work of management root and branch." The first winners have been chosen and you can read their ideas and winning entries.
The next part of the challenge will be announced soon.
