Tässä systemaattisessa kirjallisuuskatsauksessa tarkastellaan kokonaisarkkitehtuurin määritelmiä ja potentiaalisia hyötyjä. Kirjallisuuskatsauksen tavoitteena on selvittää, millaisia määritelmiä kokonaisarkkitehtuurille on 2000-luvulla annettu, ja mihin määritelmiin viimeisin kokonaisarkkitehtuuria käsittelevä kirjallisuus viittaa. Kirjallisuuskatsauksen tulosten mukaan kokonaisarkkitehtuurille on annettu lukuisia määritelmiä, ja myös viimeisin aihetta käsittelevä kirjallisuus viittaa useisiin eri määritelmiin. Kokonaisarkkitehtuurin määritelmiä tarkastellaan ja niistä esitetään ontologinen integraatio, jonka mukaan kokonaisarkkitehtuuri kuvaa tai on toimintaa, jossa kuvataan organisaation nyky- ja tavoitetilaa sekä sen keskeisiä osia, kuten liiketoimintaprosesseja ja IT:tä sekä näiden keskinäisiä suhteita. Kokonaisarkkitehtuurin potentiaalisia hyötyjä tutkitaan luomalla synteesi viidestä aiemmasta kirjallisuuskatsauksesta, joita tarkastelemalla voidaan havaita, että keskeisimpiä kokonaisarkkitehtuurilla saavutettavia hyötyjä ovat strategiset hyödyt sekä alentuneet kustannukset. ...
 
A review of definitions and potential benefits of enterprise architecture. This systematic literature review examines definitions and potential benefits of enterprise architecture. The aim of this literature review is to examine what kind of definitions has been given to enterprise architecture in the 21st century and to which definitions the latest literature refers. This literature review concludes that there are numerous definitions for enterprise architecture and that the latest literature refers to several different definitions. These definitions are examined and an ontological integration is presented, according to which enterprise architecture describes or is an action of describing the present and objective states of an organizations as well as its fundamental parts like business processes and IT and their interrelationships. The potential benefits of enterprise architecture are examined by presenting a synthesis of five prior literature reviews, according to which some of the most fundamental benefits of enterprise architecture are strategic benefits and lower costs. ...
