Our software verification procedures during the development and implementation phase include design reviews and code reviews to ensure that the code we deliver is reliable, well-documented and easy to maintain.

Integration & Testing

Our integration methodology builds on the rigorous validation, verification and testing that has been conducted prior to this stage. Before delivering an application or system, we conduct formal acceptance tests to verify that the delivered software complies with its functional specification. In addition to testing of AVISTA-developed software, we also serve as independent testers of systems developed by third parties for our clients, provide support for on-site testing, and assist in verification of compliance with national and international guidelines and standards.
