disponibilitat

Disponibilitat is the Catalan term for availability, describing the state of being accessible, usable, or ready for use when needed. In everyday language it refers to whether a person or resource can be contacted, reached, or employed at a given moment. In technical and service contexts, disponibilitat focuses on the ability of systems, services, and networks to function and be accessible to users.

In information technology and service management, disponibilitat is closely linked to uptime and service reliability. It encompasses factors such as hardware and software readiness, network connectivity, and the absence of unplanned outages. Availability is often expressed as a percentage of time a system is operational within a specified window, for example a month. Common sub-concepts include inherent availability (the design and components that enable uptime) and operational availability (the realized uptime after considering maintenance and failures). Service providers frequently specify availability targets in service level agreements (SLAs).

Measurement and practice use metrics such as uptime, downtime, mean time between failures (MTBF), and mean time to repair (MTTR). Achieving high disponibilidade involves redundancy, failover mechanisms, load balancing, preventive maintenance, monitoring, incident response, and disaster recovery planning. Availability considerations also appear in other domains, including logistics (stock availability), telecommunications, energy, manufacturing, and healthcare, where uninterrupted access to resources or services is critical.

Overall, disponibilitat highlights the expectation and engineering of reliable access to services and resources, balancing design, operation, and governance to minimize disruption and ensure user needs are met. Related concepts include SLAs, uptime targets, MTBF, and redundancy strategies.
