In the post entitled Choice in Engagement, I built on the idea that engagement is whole person investment in an interaction and emphasised that engagement is a choice.
In employee, customer, learner, user and other organisational engagement environments, individuals engage to a greater or lesser degree. Theorists and consulting organisations have posited that people can be situated on a continuum from actively disengaged (or similar term) to strongly engaged (or similar term). I suggest that identifying how engaged people are is more complex and more dynamic than this. Engagement is not a static construct.
