Thank you for your response. We must always strive to get things better, including the visualization of the process :) I see the visualizations as steps, iterations, so I’m up for taking it to the next level.
I read your article and I see what you are trying. It is true that it might seem like arrows point from practically each phase to another. My intention was to visualize the central role of prototyping. So not all arrows point to any other point but all loop back to prototyping which can be part of various sprints with various intentions (question, define etc.). I’m all for a more fluid approach and I think in reality the process is more fluid but that we split it up into parts to explain, talk about it and organize it. I think our ideas match where you talk about the sprints. I see them more as loops in the process. What I’m aiming at is creating a model that is more circular than linear, more holistic than specialist.
I think you are also seeing the downsides of splitting the process into phases. As if empathy is a phase and you don’t empathize later in the process when you have new insights. I think your proposed model of sprints is a different visualization of the same idea: that you do all things all the time, but maybe with a different intensity or different goal. I think both our models are more fluid and holistic. I just like a circular model with feedback loops more :)
If you write out the process through my circular model you get a similar process as your sprints model. Maybe I should write it out to explain the practical routes you can take through the model.
