Research in Cognitive Systems Engineering (CSE) has successfully identified basic requirements that must be met if new technology will be useful to practitioners in context. Synthesizing these basic requirements or support functions is part of a process of debate and consolidation of the foundations of the field after 25 years of productive activity (Klein, 1999; Endsley et al., 2003; Hollnagel and Woods, 2005). This work takes the "Laws that Govern Cognitive Work" which synthesize basic findings aand patterns (Woods, 2002; Hoffman and Woods, 2005) and provides the next step-a set of basic requirements or support functions for design. General requirements for effective support can be used to jump start individual development projects in any domain. Debating how to achieve these support functions helps translate the insights of cognitive work analyses into tangible new uses of technological possibilities.
