The dilemma of function activation addresses the unique vs. multiple access options to functions.

• Multi-access function activation implies flexibility in adapting the system to the operator’s interaction style. The variety of ways that the operators practice results in  reducing the speed of learning and skill acquisition and increasing the rate of interaction errors.
• Single-access implies consistent function activation, which accelerates learning, skill acquisition and improves operational reliability.

The dilemma is about how to ensure consistent function activation while enabling different interaction styles.
