Latest research indicates that construction of a communal meaning regarding coordination of complex systems development tasks should be implemented into practice, proving that far more attention should be given to the issue of communal meaning construction in organizations. Using Activity Domain Theory for Managing Complex Systems offers a new approach towards managing complex systems that informs the co-construction of technical support for coordination and communal meaning regarding this support. Compiling and structuring empirical observations from the Ericsson(TM) Company and theoretical developments from the perspective of meaning construction, this unique book combines a deep understanding of concrete, every-day conditions of the telecom industry with innovative theoretical development of the Activity Domain Theory (ADT).
