First-order approximations, to adopt a metaphor from fluid dynamics, aretractable solutions that partially solve specific problems with knowntrade-offs.
Definition of first-order approximations.
Ackerman argues that CSCW needs a set of approximations that drive the development of initial work-arounds for the socio-technical gaps.
Essentially, how to satisfy some social requirements and then approximate the trade-offs. Doesn't consider the product a solution in full but something to iterate and improve
This may have been new/radical thinking 20 years ago but seems to have been largely adopted by the CSCW community
