Chain Reaction is a team building activity that develops excellence in teamwork and project management skills by stimulating creativity and process innovation. Reaction in chain mimics the organization and coordination in a real-life project where teams are limited by time and resources. Relying on solving, creativity and communication skills, teams must work together effectively, starting from the design phase to achieve a realistic goal. Team dynamics and human resource management are tested from the planning stage, where the design is divided into small segments, requiring both human and physical resources to be divided into smaller groups. The build and test phases require coordination between teams and between different project management strategies – does each component of the system work individually and also is connected to the rest of the components to generate a cause-and-effect chain reaction? Under this program, the creativity and innovative spirit of the teams will be left to their own free will based on predetermined criteria such as efficiency in design and/or construction, resource efficiency, design, innovation, etc. *** This activity is released under the terms of the Catalyst Teambuilding license.
