Policy changes should be rolled out gradually

Policy changes should be rolled out gradually Every software developer knows that when you change a service you don't just modify the code, release it, and hope that everything works correctly. You first:test the change extensively with both unit and integration tests.run the change in a dev/staging environment used only internally to flush out any potential issues before they hit customers.ensure you have monitoring systems setup to detect any problemsgradually rollout more and more requests to the newer version of the service, monitoring for issues the whole way.ensure you have the ability to rollback if there's any regressions.All this, just to allow users to share a file, or view the website in dark mode. Meanwhile when the government decides they should overhaul the school system for every child in the country they just YOLO it. Hopefully its an improvement, but if it isn't there'd be no way to know, and there's definitely no set point to review policy and roll it back if it isn't working out.It doesn't have to be this way.The majority of significant government policy changes can be tested robustly, by randomly choosing some subset of the affected entities to apply it to. For example, if overhauling the public school system, randomly choose 20 school districts across the country to apply the changes to initially, and then apply it to the rest only if it appears to be working out in the long term.The overall process would be:Legislators draft a bill.They are responsible for choosing the suitable level of granularity at which to apply the bill to in the testing period (e.g. individual schools, school districts, states, etc.)In the bill, they indicate both the final state of the legislation, and where necessary, clarify the status of the legislation in the testing period where it's partly rolled out (e.g. if the bill has some parts that apply to individual schools, and some parts that apply to a country wide examining authority, it states that in the testing period
