Previous academic efforts to support ITO decision incorporated a limited number of factors, which is over-simplification of multi-faceted real world problems. In this paper, after doing in-depth literature review for identifying influencing factors on such ITO decisions, a model with an application of Fuzzy TOPSIS based approach is proposed to rank and prioritize the alternatives. Throughout this study, the authors use data from a real banking case to run the model for supporting outsourcing decision for five ATM, POS, tele-banking, mobile, and internet-banking services. The proposed model can help ITO decision makers advance their decision making process, especially where parameters involve uncertainties and hardly can be assessed by human judgment.<\/jats:p>","DOI":"10.4018\/ijeis.2017040103","type":"journal-article","created":{"date-parts":[[2017,5,31]],"date-time":"2017-05-31T13:06:40Z","timestamp":1496236000000},"page":"34-49","source":"Crossref","is-referenced-by-count":8,"title":["A Fuzzy TOPSIS Method for Selecting An E-banking Outsourcing Strategy"],"prefix":"10.4018","volume":"13","author":[{"given":"Ahad Zare","family":"Ravasan","sequence":"first","affiliation":[{"name":"Department of Industrial Management, Faculty of Management and Accountancy, Allameh Tabataba'i University, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Payam","family":"Hanafizadeh","sequence":"additional","affiliation":[{"name":"Department of Industrial Management, Faculty of Management and Accountancy, Allameh Tabataba'i University, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laya","family":"Olfat","sequence":"additional","affiliation":[{"name":"Department of Industrial Management, Faculty of Management and Accountancy, Allameh Tabataba'i University, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammad Taghi","family":"Taghavifard","sequence":"additional","affiliation":[{"name":"Department of Industrial Management, Faculty of Management and Accountancy, Allameh Tabataba'i University, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2432","reference":[{"key":"IJEIS.2017040103-0","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2010.02.103"},{"key":"IJEIS.2017040103-1","doi-asserted-by":"publisher","DOI":"10.1108\/02637471111122471"},{"key":"IJEIS.2017040103-2","doi-asserted-by":"publisher","DOI":"10.1016\/j.im.2003.09.001"},{"key":"IJEIS.2017040103-3","doi-asserted-by":"publisher","DOI":"10.1016\/j.dss.2013.04.007"},{"key":"IJEIS.2017040103-4","doi-asserted-by":"publisher","DOI":"10.1016\/0268-4012(92)90049-V"},{"key":"IJEIS.2017040103-5","doi-asserted-by":"publisher","DOI":"10.1016\/j.im.2012.03.001"},{"key":"IJEIS.2017040103-6","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijpe.2008.07.022"},{"key":"IJEIS.2017040103-7","doi-asserted-by":"publisher","DOI":"10.1016\/j.jwb.2006.01.011"},{"key":"IJEIS.2017040103-8","first-page":"1","article-title":"Lessons from Dutch IT-outsourcing success and failure.","volume":"1","author":"G.
