The final schema involves information seeking ...
Channel expansion theory builds from a variety of theoretical perspectives that address perceptions of media channels. It is developed from media richness theory as studies tested directly using media richness theory have turned out to have confusing results such as e-mail.
Measurement and evaluation should identify outputs, outcomes, and potential impact [10] Outcomes and impact should be identified for stakeholders, society, and the organization [ 10 ] Communication measurement and evaluation should include both qualitative and quantitative analysis [ 10 ]
