Effective industry and public project planning, design and execution are increasingly dependent on instant collaboration to deal with unexpected situations and events, caused by nature, technology or people. Agile approaches to enterprise design, responding to growing variety, emergence and complexity of sectors are being researched. This paper presents an agile approach, and illustrates its potential through reporting from pilots and case studies. Agile model-based and architecture-driven solutions have been prototyped. These have a potential for removing interoperability barriers, managing dependencies and complexity, enabling iterative design and smart adaptive operations of products and services. Instant collaboration is triggered by parameters and rules linking affected workspaces, and enabled by architecture-driven knowledge spaces integrated in a visual role-oriented and adaptive work environment. Local practices and work-centric context as well as global context are captured.
