TheImportanceofGoodCommunications

However,firmsoftenhavecommunicationproblemsthatcanunderminetheirperformance.Inmanycases,theseproblemsoccurbecausemessagesarepassedoninaninappropriateway.Thereare,ofcourse,severalwaysofconveyinginformationtoothersintheorganizationwhichincludespeakingtothemdirectly,e-mailing,telephoningorsendingamemo.Themostappropriatemethoddependsonwhatexactlyitisyouarecommunicating.Forexample,anythingthatisparticularlysensitiveorconfidential,suchasanemployee'sappraisal,shouldbedoneface-to-face.
