Navigating complex systems design with the PEArL framework

The problems and difficulties in complex systems design are more subjective and ambiguous than commonly acknowledged and soft systems tools and frameworks can help to address gaps in knowledge and support judgement throughout the design process. This paper describes the application of the PEArL framework, an intellectual device based on systemic principles, to support a team in a complex product environment manage the ‘soft’ challenges in complex systems design. The PEArL framework facilitated the creation and management of inter-disciplinary relationships in a pressurised business environment and provided a structure for validation of the way in which the design process had been undertaken.
