Following on from recent posts on the nature of design thinking I want to clarify two things. I am not opposed to design thinking or even thinking about design as this blog demonstrates! Simply, my thoughts as expressed here were that if you want people to better understand design thinking, just get on with it an involve them in it or at the very least provide them with a concrete example rather than an abstract diagram of the process you are trying to sell them. This could perhaps be considered a Constructivist viewpoint as opposed to a Cognitivist world view.
Scenario modelling can also be considered a constructivist tool. As a designer you probably use scenario modelling to predict, impose or evaluate user behaviour by ‘constructing’ that world in some manner. This might be virtually or in the form of organised user testing and evaluation. Do you use scenario modelling to anticipate or communicate your own role within the design process?
The second issue I want to explore and it relates to this earlier post as well. Is the question of whether design is a skill or rule based process?
Systems and therefore ‘systems theory’ in it’s purest form requires human operators whether designer or user to follow a defined path or at least operate within a set of constraints. I interpret the ‘design thinking’ as practiced and encouraged by IDEO, with their method cards etc. as ‘rule based’ at least in the deductive phase (understanding the context) of the design process.
Do you follow a rule based or heuristic approach as part of your efforts to understand or predict the environment and users you are designing for? Does it work?
Other designers of course may rely simply on their own subjective or ‘skill based’ judgements about the environment or context as opposed to following a rule or heuristic approach to design. This is perhaps symptomatic of the ‘ego-design’ process that Molenbrook refers to here, in describing the differing approaches many designers have to ergonomics data.
Most importantly, which of these ways of conceptualising the design process are easier to engage clients, users and yourselves as designers with?
