Looking at the results of employee engagement surveys and developing action plans based on them requires looking at the items on the survey in terms of what they measure. Do they measure satisfaction? Do they measure motivation? Once this is done, and only once it is done, does it make sense to think about action items such as making work more interesting, providing more job security, or rewarding performance with bonus plans?
Yes, engagement scores are indicators of how good or bad a work situation is. In most cases, it is better to have higher rather than lower engagement scores, but in order to take action directed towards improving organizational performance, the items need to be looked at separately and used to make data-based changes that will drive employee retention, performance, and commitment.
