Our organization has 6 applications that our end-users interact with on a daily basis. Each application is developed by a separate team and lives in their own solution files. We've made an effort in the past 12 months to enforce design standards around our applications so that for the most part they each look and feel the same. Due to the coupling, legacy code and old controls, it's difficult to make sweeping design changes across all the applications. My question is, in this type of environment if we want to take our organization to the next step in terms of UI and UX, how would we go about it considering it's unreasonable to assume that it can be done to all six applications simultaneously within a timely manner? Is it okay to focus on one application and make it the best that we can and if so, how will our user percieve that? Will we detriment the user experience by having one application look different than the others that the user interacts with?
Example workflow:
Login > application 1 > application 2 > application 1 > application 3 > application 1 > logout
