käivitatavuse

Käivitatavuse (startability) is a term used to describe the ease and reliability with which a system, machine, or process can be started from an initial or resting state. It encompasses how readily a device or software component transitions from idle to active, including the speed, success rate, and required conditions for a successful start. The concept is applied across mechanical engineering, electronics, and information technology to assess how promptly and dependably a system can be brought to a usable state.

In mechanical contexts, käivitatavus covers factors such as energy requirements, friction, lubrication, temperature, and component wear. For engines and motors, good käivitatavus means reliable cold starts, minimal cranking time, and consistent performance on first ignition, even under adverse conditions. In consumer electronics, it relates to how quickly a device powers up and becomes responsive after pressing the power button or charging from a low battery state.

In software and IT, käivitatavus refers to startup latency and readiness. This includes boot or service initialization time, dependency loading, and the time until a system is fully available to handle requests. Techniques to improve it include caching, parallel initialization, lazy loading, and minimizing initialization work.

Measuring käivitatavuse typically involves start time, first-attempt success rate, and time to reach a defined readiness state. It is an important consideration for user experience, reliability, and operational efficiency.
