Strategy decides what a business should do; operations is how it gets done. It covers the processes work flows through, the systems that support them, who owns what, and the rhythm that keeps it all moving. When operations is healthy, the business scales smoothly. When it is not, growth exposes the cracks.
Most businesses that feel chaotic as they grow do not have a strategy problem. They have an operations problem nobody has had time to name. An Operations Audit is the usual way to find out which.
