Hello, you can talk to Alejandro Masferrer, his book proposes tools and methods to engage in co-creation processes. Also, probably some or the papers published in CoDesign might have described their co-creation process. The full name of the journal is: CoDesign, International Journal of CoCreation in Design and the Arts.
Perhaps Wina Smeenk, specialist in societal impact design and empathic co-design? She developed the Co-Design Canvas: Method Co-Design Canvas for multi stakeholder collaboration: manual...
I’m dismayed with this subject. The idea of design I know has always been based on co-design ideas. Though Co-Design and Co-Create are updates to the older ways we expressed a normal design concept and development. -- Until the late 1990’s we always worked with end users. By my experience the change came with an abundance of digital tools and software. The rush to market for attention to the newest devices led nearly all these groups to let the end user de-bug and refine the designs. To save money (the quick to market, lean and bare-bone approach to design), users were excluded and quality control depts disbanded. Today we accept poor design as an alternative to higher costs. But also accept new design based on marketing VS our actual needs. See automobile “iPad-like” control screens that change the UI and UX for each function as an example of design that ignores users. See Sony camera menus as a 2nd example.
I suggest you look (1st link below) at and contact “IDEO”, a US design studio that is the originator of what today we call “design thinking”. For 50 years they based their design philosophy on the user. From my reading of the co-design journals
and Masferrer’s workshops I came to conclude they're based on IDEO ideas. But missing the simplicity of user centered design in favor of developing a new philosophy. -- I’ll add two links to supplement those already posted.
