👉 Deployment math, also known as deployment mathematics or deployment calculus, is a formal method used to specify and verify the behavior of software systems during their transition from development to production. It involves defining the conditions under which a system can safely and correctly operate in its deployed environment, typically by mathematically modeling the system's behavior under various inputs and constraints. This approach uses logical formulas and algebraic structures to describe system requirements, such as safety properties (ensuring the system never enters an unsafe state) and liveness properties (guaranteeing that certain desirable states will eventually be reached). By rigorously analyzing these mathematical models, deployment math helps ensure that the system behaves as intended in real-world scenarios, reducing the risk of bugs and failures in production.
