4 EA, SOA, ad SOEA EA is a established disciplie that deals with architectures i eterprise scope. It s a subject domai that is idepedet of approaches ad methodologies for its developmet ad presetatio SOA is a architecture style ad approach that emphasizes well-defied, loosely coupled, ad sharable services EA provides SOA with a eterprise view; SOA brigs ew agility to EA by deliverig tagible results, which helps EA get broader acceptace ad icreased usability SOEA: EA modelig with service-orieted style ad approach SOEA uses SOA as a practical modelig approach for appropriate part of EA developmet. SOEA bridges EA with solutio architecture ad implemetatio by layered service compoets across busiess, applicatio, ad techology. SOEA liks eterprise model with service model that eables a better implemetatio from busiess strategies to IT capabilities.

7 Cocept of Service Orieted Eterprise Service Orieted Eterprise (SOE): is a eterprise that applies service orietatio to its full scope busiess maagemet ad operatios where appropriate. The SOE Practice takes guidace from SOEA is eabled by SOA implemetatio i busiesses, applicatios ad systems is facilitated by Service Orieted Ifrastructure (SOI) SOEA ad SOE, Ya Zhao, Ph.D; The 23 rd Ope Group Eterprise Practitioers Coferece The MITRE Corporatio.

9 Relatioship of SOE with SOA As architecture is a part of the plaig phase for a eterprise, SOA (or SOEA) is a part of the plaig phase for SOE As a eterprise uses service orieted approaches across their eterprise IT plaig ad operatio lifecycle, the emergece of a SOE will be the atural evolutioary step forward from SOA. SOE provides orgaizatioal eablemet, capabilities, ad readiess i achievig the widely claimed beefits of SOA. It provides eviromet that eables plaig ad executio of shared services across orgaizatio boudaries SOE esures a ed to ed adoptio of service orietatio ad effectiveess i executio.
