"Many of the common concepts of power in business are so close to perfectly wrong that it's amazing any work happens at all..." The physics definition of power is 'the ability to do work'; most social definitions are closer to the ability to avoid it. This insight provides opportunities for a radical re-think of power and response-ability at work. Linking the human side of systems into the architecture of the enterprise creates workplaces that are more effective, empowering and profitable for everyone involved. This enlightening and enlivening book explains the interplay of power, property and responsibility in the business context - how it works, why it doesn't, and what to do about it. Topics covered include: - how to identify power in the workplace - both functional and dysfunctional - how to enhance responsibility and 'response-ability' at work - how to resolve differences of scale, from 'I' to 'We' to 'Us' to 'Them' - how to avoid 'power-traps' that could put the enterprise at risk - how to design systems that improve purpose-fulfilment, relationship-management and knowledge-technology in the enterprise The book includes a diagnostic checklist on power, property and responsibility, and also describes the background to other Tetradian tools and techniques such as the SEMPER whole-of-enterprise metric. If you want to include the human side of systems in your enterprise-architecture, this is one book you'll definitely need.
