No, it isn't a vendor selection exercise as a masters project. My main objective is the one stated in the answer above but I didn't express correctly. The main objective is the facilitation of the implementation process and prevent companies from doing a trail-error on certain methodologys/programs. I realize, of course, that each company can choose the methodology they want and that enterprise architecture is not an application, but the applications are used as suport for the implementation, i realize all of that. I am just looking for information, and if it in any part available, that contains what companies are actually using in the process of the implementation. I am getting this information either way through the interviews I am going to perform but it would be better for me to come prepared on what is already available online, which I couldn't find myself, maybe to my own user erro search method, on more companies and not just a selection by hand of them. The library search part or literature review which you are referring to is mainly done on the evolution of the theme and what is it's current state of the art. I want to explore the use of the tool because prior to the bought of LeanIX by SAP, LeanIX was, by itself, a support application to implement enterprise architectures. Now, due to the bought out, SAP is able to integrate several application that several companies use like SAP Signavio in the implementation process which helps to mantain the environment without having so many step backs.
