The current place I am at has a history of eng doing anything product wants and not saying no or "yes and." As a result, the eng side is a mess, builds are slow, service and data boundaries are muddled, and shipping working software continues to slow. Incidents are rising and customers are starting to churn and larger customers are harder to sign.
As part of eng leadership, my role is helping teams learn what a healthy product and eng relationship looks like, which includes pushing back and gaining alignment on the need for eng focused projects.
