Unorganisation
Unorganisation is an approach to organisational structure and design that consciously removes or avoids layers of management and bureaucracy, eschews job titles, and instead attempts to operate with the minimum of formal structure so as to become as flexible and effective as possible.
Unorganisation is not the same as disorganisation (a chaotic environment in which little can be easily or quickly achieved); neither is it the same as being disorganised, a term usually applied to industries with non-unionised labour (or just being personally untogether).
