Résumé	Media richness analysis applies Daft and Lengel's media richness theory to evaluate communication channels by their capacity to carry rich information and to assess how well a channel fits the equivocality of the task at hand. Rooted in organizational communication, it provides criteria — feedback immediacy, multiplicity of cues, language variety, and personal focus — for ranking channels from lean (a memo) to rich (face-to-face) and for diagnosing whether managers and teams are matching channel to message appropriately.	Content analysis is a systematic research technique for reducing text, visual, or media material into coded categories so that patterns can be counted, compared, and interpreted. Formalised by Klaus Krippendorff in his widely cited methodology textbook (latest edition 2018), the method sits at the boundary of qualitative and quantitative inquiry: it imposes structured, replicable coding on inherently meaning-laden material.	Manifest content analysis is a quantitative research technique that systematically counts the explicit, surface-level features of communication messages — words, sources, themes, images, or actors that are directly visible in the text or media artifact — according to a predefined coding scheme. Rooted in Bernard Berelson's classic definition of content analysis as the 'objective, systematic, and quantitative description of the manifest content of communication,' it is one of the foundational empirical methods of mass communication and media research.
