Some Principles of Human-Centered Computing

From Perspectives On Cognitive Task Analysis: Historical Origins and Modern Communities of Practice
(emphasis mine)

The Aretha Franklin Principle Do not devalue the human to justify the machine. Do not criticize the machine to rationalize the human. Advocate the human–machine system to amplify both.
The Sacagawea Principle Human-centered computational tools need to support active organization of information, active search for information, active exploration of information, reflection on the meaning of information, and evaluation and choice among action sequence alternatives.
The Lewis and Clark Principle The human user of the guidance needs to be shown the guidance in a way that is organized in terms of their major goals. Information needed for each particular goal should be shown in a meaningful form and should allow the human to directly comprehend the major decisions associated with each goal.
The Envisioned World Principle The introduction of new technology, including appropriately human-centered technology, will bring about changes in environmental constraints (i.e., features of the sociotechnical system or the context of practice). Even though the domain constraints may remain unchanged, and even if cognitive constraints are leveraged and amplified, changes to the environmental constraints will impact the work.
The Fort Knox Principle The knowledge and skills of proficient workers is gold. It must be elicited and preserved, but the gold must not simply be stored and safeguarded. It must be disseminated and used within the organization when needed.
The Pleasure Principle Good tools provide a feeling of direct engagement. They simultaneously provide a feeling of flow and challenge.
The Janus Principle Human-centered systems do not force a separation between learning and performance. They integrate them.
The Mirror– Mirror Principle Every participant in a complex cognitive system will form a model of the other participant agents as well as a model of the controlled process and its environment.
The Moving Target Principle The sociotechnical workplace is constantly changing, and constant change in environmental constraints may entail constant change in cognitive constraints, even if domain constraints remain constant.
