Flutter App Development : What To Verify Before, During, And After | ClickMasters Checklist Engineering Baseline
complete all pre-project checklist items before signing a development contract. Items marked are non-negotiable a vendor who will not complete them is a vendor who will produce surprises during delivery.
Industry-standard compliance and best practice implementation.
review the sprint checklist at each sprint review. A story that does not pass all sprint checklist items is not a completed story it should not be counted in the sprint velocity or reported as 'done' to stakeholders.
Industry-standard compliance and best practice implementation.
complete the pre-launch checklist before exposing the product to any external users. The pre-launch items are the ones where failures are most costly a security issue discovered after launch costs 10-100x more to address than one discovered before.
Industry-standard compliance and best practice implementation.
complete the post-launch checklist in the first 30 days. These items are not optional enhancements they are the verification that the launched product is working as intended and that the monitoring infrastructure is in place to catch problems before users report them.
Industry-standard compliance and best practice implementation.
