Measuring employee engagement over time requires different methods and tools, depending on your objectives, resources, and preferences. Common approaches include employee surveys, feedback, and behavior. Surveys can provide quantitative and qualitative data, while feedback can help you understand specific issues and build trust with employees. Observing employee behavior can reflect engagement levels and identify gaps between what they say and do. Periodic or continuous surveys can be standardized or customized to industry standards or best practices. Employee feedback channels such as performance reviews, one-on-one meetings, suggestion boxes, or online platforms demonstrate that you value their opinions. Employee behavior such as attendance, productivity, quality, collaboration, innovation, or advocacy affects their performance and outcomes.
