As with the previous stages, this stage requires both a divergent and convergent phase. In the divergent phase, one of my favourite tools to use is the Disney Strategy to do the testing.
This can be a fun way of looking at the factors that can help or hinder the implementation of a solution. It’s based upon Walt Disney’s way of working, and developed into a tool by Robert Dilts, one of the founders of Neuro-Linguistic Programming.
It simulates the kind of feedback that could be encountered when a solution is put into practice. So, it unearths the barriers there may be to implementation. It then offers a process for reflecting on how these can be overcome. This process can be a very valuable way of testing any ideas before presenting them to wider audience. It’s a kind of bullet-proofing.
