Big Bang Change
Big Bang Change is a software development and deployment methodology where all changes to a system are implemented and released at once, rather than incrementally. It involves replacing an entire system or making major updates in a single, large-scale release, often with significant downtime or disruption. This approach contrasts with gradual rollout strategies like phased deployments or feature toggles.
Developers should consider Big Bang Change when dealing with legacy system replacements, major platform migrations, or when incremental changes are impractical due to technical constraints or business requirements. It is often used in scenarios where a complete overhaul is necessary, such as moving from an on-premise system to a cloud-based solution, but it carries high risk due to potential failures and user disruption.
