A method for selective application of enterprise application integration (EAI) for a project under consideration involves a computer implemented model. The method includes defining a plurality of sets of EAI practices including a full EAI approach, a partial EAI approach, and a minimal EAI approach. Classifications are defined for each approach. Classifications are defined for applications, business objects, and business processes. The model generates an output indicative of a recommended set of EAI practices. In determining the output, the model considers factors including the classifications for the applications, business projects, and business processes involved in a project.
