Internal communication surveys are conducted yearly and may include additional questions to provide insights into communication effectiveness. It is important to measure awareness, attitudes, and knowledge before and after major communication efforts and initiatives to assess their impact. Regular measurement helps communicators understand shifting attitudes over time and tailor messages appropriately. Specific events can also be measured through temperature checks and pulse surveys to collect feedback. Key performance indicators should be benchmarked and tracked over time to identify emerging issues. Communication measurements may include reach, understanding, behavior changes, and impact on business goals. Both quantitative and qualitative methods can be used.
