Abstract: A virtual technical building block software development tool and a software development interface that speed accurate and quality software design are provided. The tools develop enterprise software architecture designs, and utilize a library of symbols and a virtual template. The library of symbols includes service oriented architecture symbols and enterprise application integration symbols. The template includes multiple sections to be displayed on a computing device screen. Each section includes a blank space bounded by a frame, and all of the sections are vertically aligned with one another to guide design flow. The sections of the template include, from top to bottom vertically, (1) a technical capabilities section; (2) an interaction sequence section; (3) a service topology section; (4) an integration flow section; and (5) a logging section.
