Techniques to compensate for nonlinearity of a tuning function of an oscillator are described. Examples of active optical elements include various phosphor materials for emitting light, various electrically driven light emitters and various devices that generate electrical current or an electrical signal in response to light. A determination of organizational units of users are made, staffing states are modified, and users are disallowed from making changes to a project plan based on the evaluation of the rule set as a function of the staffing state.
