Management processes have failed to keep up with possibilities to involve people in creative processes, because they do not have the mechanisms to manage their involvement. For example, there are few ways to establish contracts with people outside of a conventional scope, such as employment or agency contracts, or a volunteer or public consultation method. If people help out, their contributions are poorly documented outside of time and motion reports
Also, many people become typecast into certain roles. If you've ever known a musical composer you'll know they have amazing ways of thinking and seeing and expressing. Stamps help such people play other roles, project other principles. Because going around just composing is a tricky job to find. And not the only way that person might want to express their intentions and apply themselves.
Similarly, someone who has experience of something – going blind perhaps – has a role to play in helping others understand all kinds of things that they can't possibly understand without enormous study, and even then will not be completely authentic. But maybe that person wants to contribute to things in a way that avoids them being typecast as the blind person. A Stamp or two can help them do that.
For most of us, making sense of, defining and projecting our identity is an uncomfortable experience that we should be entitled to take our time with. Stamps allow us to play with identities, maybe even to explore new ones, some of which might conflict. To help us get space to enjoy the adventure of our working life.
