<Cesar> Before being a product, open architecture is the social organic process.
The wish can emanate from the individual or can be generated by a group of
individuals.
Can a group of people say “let’s do an open architecture!”?  As I see it, open
architecture is never the objective, it is the method of development; so what holds
the group together if it is not an objective? The altruistic nature of the project can
be a reason, if you dig altruism a little you may find self-interest under the surface.
Other dynamics such as empathy or competition guarantee cohesion to a group.
Finally the making of a group can be a celebration on its own, and it is perhaps
the first tangible manifestation of open architecture.
To keep this group alive and evolving over a long time, the roles within the group
may  change and new members from outside may replace existing members.
At some point the group assembles it potentials in relation to the outside con-
text and determines its different functions, its internal forces to articulate it into
something productive. The group even if it is made of loose social connections
deployed into space in a complex choreography, creating a new world, changing
the texture of space, absorbing the outside space inside the group superorganism.
Open architecture describes the way the people assemble, behave between each
other and as group, or multiple groups.<Cesar>
