This document discusses various diagramming techniques that can be used to analyze organizational change. It begins by explaining that organizations are complex systems composed of interrelated subsystems and components. Diagramming tools can help define, analyze, and manipulate these systems to better understand how a change might impact them. Several specific diagramming techniques are described, including input/output diagrams, flow diagrams, relationship maps, systems maps, influence charts, and multiple cause diagrams. The document emphasizes that managing complex change requires a multidisciplinary approach involving multiple analytical techniques in addition to diagramming. It also introduces an Intervention Strategy Model (ISM) as a structured process for analyzing and implementing change through definition, evaluation, and implementation phases.
