Change Plot

Change Plot is a strategic design thinking and visualization tool used to map and analyze the transformation of products, services, or systems over time. This methodological framework enables designers and strategists to document, understand, and plan the evolution of design elements by plotting significant changes across temporal dimensions. The tool consists of a graphical representation where time typically forms the horizontal axis, while various design attributes, features, or characteristics are mapped along the vertical axis, creating a comprehensive visualization of transformative patterns. Originally developed within the context of product design evolution studies, change plots have since become instrumental in multiple design disciplines, including service design, user experience design, and systems design. The methodology allows practitioners to identify trends, anticipate future developments, and make informed decisions about design iterations. When creating a change plot, designers typically document both incremental improvements and radical innovations, helping to distinguish between evolutionary and revolutionary changes in design development. This analytical approach proves particularly valuable in design research, where understanding historical patterns can inform future design directions. The tool's effectiveness has been recognized in various design competitions, including the A' Design Award, where projects demonstrating thoughtful implementation of change analysis often receive recognition for their strategic approach to design evolution. Change plots also serve as valuable communication tools, enabling designers to effectively convey complex temporal relationships and development patterns to stakeholders, team members, and clients, while facilitating more informed decision-making processes about future design directions and innovation strategies.
