Esri follows a standard, codified project implementation methodology. Our methodology is a pattern-based approach that emphasizes strong customer collaboration and high-quality system integrations. It combines sound IT project management and engineering processes with best practices we have adopted based on more than 40 years of experience implementing GIS.
There are many valid project life cycles. We will recommend the appropriate life cycle for your project based on an evaluation of your needs and the key characteristics of your project.
We prefer an evolutionary or staged-delivery life cycle that is agile and involves significant interaction with customers. This approach prioritizes requirements into manageable increments. Each increment provides for regular technical and management review, giving you a high level of visibility into the design and progress of your solution.
This approach accommodates the sometimes-transformational nature of the systems we design without requiring an organization to change overnight.
