The Skills, Rules, Knowledge (SRK) Framework
The Skills, Rules, Knowledge (SRK) framework or SRK taxonomy defines three types of behaviour or psychological processes present in operator information processing (Vicente, 1999a). The SRK framework was developed by Rasmussen (1983) to help designers combine information requirements for a system and aspects of human cognition. In EID, the SRK framework is used to determine how information should be displayed to take advantage of human perception and psychomotor abilities (Vicente, 1999b). By supporting skill- and rule-based behaviours in familiar tasks, more cognitive resources may be devoted to knowledge-based behaviours, which are important for managing unanticipated events. The three categories essentially describe the possible ways in which information, for example, from a human-machine interface is extracted and understood:

Famous quotes containing the words knowledge and/or framework:
“Horse-play, romping, frequent and loud fits of laughter, jokes, waggery, and indiscriminate familiarity, will sink both merit and knowledge into a degree of contempt. They compose at most a merry fellow; and a merry fellow was never yet a respectable man.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“The city is a fact in nature, like a cave, a run of mackerel or an ant-heap. But it is also a conscious work of art, and it holds within its communal framework many simpler and more personal forms of art. Mind takes form in the city; and in turn, urban forms condition mind.”
—Lewis Mumford (1895–1990)
