From left to right (process), top to bottom (organization). Now, it’s a circle for process and a network for organization.
“The representation of an actual UX design process with a design model probably presents an overly simplified view of the process. However, the design model serves a descriptive function. Additionally, having an abstract representation of the design process in the form of a design model highlights the essential forces driving the process of UX design: simultaneous changes in the problem and solution spaces. In this article, I’ve proposed a possible adaptation of the spiral model for a UX design process. By incorporating continuous changes to our understanding of the problem space into a systematic investigation of the solution space, we can synchronize these self-reinforcing forces and generate high-quality UX designs. However, several important aspects of the UX design process require further discussion of empirical evidence and feedback – for instance, adapting this model to agile software development.”
