Abstract: Systems, apparatuses, methods, and computer program products are disclosed for measuring employee engagement. An example method includes receiving, by communications circuitry, an exogenous event report and identifying, by a frequency modulator and based on the exogenous event report, a frequency at which to deliver an employee survey to an employee. The example method further includes causing, by an engagement engine, delivery of the employee survey to the employee based on the identified frequency and receiving, by communications circuitry, a response to the employee survey. The example method further includes storing the received response in a memory as a measure of employee engagement.
