ESSI Acronym for European Systems and Software Initiative. Acronym for European Systems and Software Initiative. A program of technology transfer and software process improvement within ESPRIT III. As distinct from the main body of ESPRIT, which supported R&D projects, ESSI had the goal of improving software development practice in industry and business. The ESSI pilot phase (1993–96) supported 93 Application Experiments (process improvement activities), nine Dissemination Actions, and a training program (ESPITI: European Software Process Improvement Training Initiative). The Framework IV Programme, 1995–99 (see ESPRIT), included a continuation of ESSI under the name Software Best Practice.
