    Why Change Intelligence is Necessary to Effectively Troubleshoot Modern Applications

    Change Intelligence is often a missing component in incident management. Successfully correlating monitoring and observability data to arrive allows engineers to arrive at the root cause more rapidly. Telemetry provides the building blocks that enable change intelligence to identify and map the root cause, based on changes in the system and their broader impact.

    Lightweight External Business Rules

    Complex enterprise applications usually come with varying business logic. Such conditions and subsequent system actions, known as rules, are ever varying and demand involvement of domain specific knowledge more than technology and programming. The rules must reside outside the codebase, authored by people with core domain expertise with minimal tech knowledge.
