EnterpriseArchitecture:MuchMoreThanYou’reThinkingMostusageoftheterm“EA”isfocusedprimarilyonwhatmightmorepreciselybecalled“ITarchitecture”or“informationsystemsarchitecture,”whichisconcernedwiththelogicalandphysicaldescriptionsofdata,applications,andhardwareassets.

EA“isablueprintfororganizationalchangedefinedinmodels[usingwords,graphics,andotherdepictions]thatdescribe(inbothbusinessandtechnologyterms)howtheentityoperatestodayandhowitintendstooperateinthefuture;italsoincludesaplanfortransitioningtothisfuturestate."AndblendinthenotionthatEAisallaboutcreatingadynamictoolforunderstandingtheenterpriseandmanagingenterprisetransformation,ananalyticaltoolforcontrollingenterprisecomplexity,asharedlanguagetofacilitateandexpeditecommunicationabouttheenterprise,andadecision-supportingknowledgebasetohelpmanagementcreateandmorequicklyachieveobjectiveslikestrategicadvantage,alignment,agility,efficiency,synergies,andvalue.

Step4.Identifyyourframework
