Application Design and Development
PLEXOS international provides custom application design, development and implementation services for new products, product customization, or legacy code conversion projects. Projects typically begin with the development of a Performance Requirements Specification (PRS), complete with detailed software specifications and timelines for delivery. The PRS becomes the basis for the contracted software delivery and is signed by both PLEXOS international and the client prior to notice to proceed on the project.

A team of experienced programmers (C/C++/ C#/.NET/Java/Assembler/Fortran/Visual Basic), working with source and version control systems, develops all projects. As the software is developed, new versions are created for testing and certification by the PLEXOS international staff and the client. When the software is completed and accepted by the client, bug tracking and fixes are handled by our development team via our IssueManager application on the Internet. As issues are identified and resolved, new releases of the software are created and made available for download in accordance with our support and maintenance agreements.
