Visualisation and sketching also support the fluidityand non-linearity of creative process, through whichdesigners can discover and explore ideas andrealise their thinking. The non-permanent nature ofsketches allows for experimentation and playthroughout the design process. From our study,most designers envisioned integrating Evolverwithin the early stages of their design processbecause it provides a platform to externalise andvisualise their ideas. They suggested that theexposure to the multiple generations of their ideaassisted with the ambiguity of the front-end throughdiscovery, framing out early ideas andbrainstorming.“I would mainly use Evolver as a brainstormingtool within the early stages of my process, as itsupports the flexibility of ideas and quicklyexposes me to an extensive range ofalternatives.” (P4, Interview)Evolver facilitated the designer’s ability to enter amore intuitive or associative mode of thought byeasing some of the effort in manually visualisingalternative design concepts:“Sketching stuff out on paper takes more energyand tweaking – Evolver allows me to visualiseeasier, have a dialogue and collaborate with thedesign space.” (P3, Interview)The designers in the study described Evolver as an“invisible teammate” who they can collaborate withat any stage of their design process. Evolver couldbe used flexibly at different stages of the designprocess to support different tasks and modes ofthought, including both the generation andcommunication of ideas. The participantscommented that Evolver acts as a dialogue fordesigners when communicating their mentalmodels and understanding of a design situation toclients and others involved in the design project.
