TheImportanceofGoodCommunications
Effectivecommunicationisessentialforallorganizations.Itlinkstheactivitiesofthevariouspartsoftheorganizationandensuresthateveryoneisworkingtowardsacommongoal.Itisalsoextremelyimportantformotivatingemployees.Staffneedtoknowhowtheyaregettingon,whattheyaredoingrightandinwhichareastheycouldimprove.Workingalonecanbeextremelydifficultanditismucheasierifsomeonetakesaninterestandprovidessupport.Employeesneedtounderstandwhytheirjobisimportantandhowitcontributestotheoverallsuccessofthefirm.Personalcommunicationshouldalsoincludetargetsetting.Peopleusuallyrespondwelltogoals,providedtheseareagreedbetweenthemanagerandsubordinateandnotimposed.
However,firmsoftenhavecommunicationproblemsthatcanunderminetheirperformance.Inmanycases,theseproblemsoccurbecausemessagesarepassedoninaninappropriateway.Thereare,ofcourse,severalwaysofconveyinginformationtoothersintheorganizationwhichincludespeakingtothemdirectly,e-mailing,telephoningorsendingamemo.Themostappropriatemethoddependsonwhatexactlyitisyouarecommunicating.Forexample,anythingthatisparticularlysensitiveorconfidential,suchasanemployee'sappraisal,shouldbedoneface-to-face.
