A client wants to move from two releases a year to monthly. What has to change?

Batch size falls, so several things that were survivable at two releases a year stop being survivable.

Testing is the binding constraint. A three-week manual regression pack consumes a monthly cycle. Automated regression across the critical business journeys is not optional at this cadence, and it is the largest single investment.

Environments have to support a shorter cycle: staging refreshed or aligned often enough to be trustworthy, which usually means confronting the Full sandbox refresh interval and either changing the environment type or keeping staging aligned by deploying to it exactly as to production.

Deployment has to be repeatable. Hand-assembled change sets do not survive twelve releases a year; the release has to be built from the repository so the artefact that passed staging is provably the artefact that ships.

Governance has to be right-sized. A review board that meets monthly and reviews everything becomes the release schedule. Risk tiering and pre-approved patterns are what let governance keep up.

The compensation I point out is that smaller releases are lower risk individually and much easier to diagnose. The cost is front-loaded — automation and environments — and the benefit accrues afterwards, which is exactly the shape of investment that needs a sponsor.
