# Workflow Bottleneck Review with Dhruv Jain

> A 30-minute conversation about one recurring workflow that is causing repeated chasing, manual work or unclear handoffs. Bring one example. We will discuss where it gets stuck and whether to simplify the process, use your existing tools, or explore a scoped repair. If the scope is still unclear, we can discuss a separate paid assessment. No preparation or system access is required. There is no obligation to proceed.
