Global engineering and consulting firm Tetra Tech consolidated 100+ ERP systems into Oracle E-Business Suite hosted on Oracle Cloud Infrastructure and then built an interactive analytics platform on Oracle Autonomous AI Lakehouse and OCI Generative AI so business users could access complex finance and project performance metrics on demand. Using Oracle Digital Assistant with text, chat, and voice interfaces, the platform lets finance and project teams ask nuanced questions in natural language, minimizes information delays and inconsistencies, and provides secure access to metrics across projects, customers, and regions. Oracle APEX and Oracle Analytics support role-based reporting, while the company is also planning AI agents for routine tasks such as transaction error fixing and time-entry streamlining.
