In practice, töökindlaks is a quality attribute emphasized in product design, testing, procurement, and maintenance. It appears in specifications and quality assurance arguments to indicate that a device, system, or service can be trusted to function as intended. The related noun töökindlus denotes the overall reliability, durability, and steadiness of performance over time.

Reliability is typically measured and demonstrated through testing and metrics. Common measures include mean time between failures (MTBF), failure rate, and uptime. Testing methods include life testing and accelerated life testing, as well as environmental or stress testing to assess performance under adverse conditions. Standards and frameworks such as ISO 9001 (quality management) and IEC 61508 (functional safety) are often referenced when discussing or guaranteeing töökindlus in professional settings.

Etymology and usage notes: the base form töökindel means reliable or dependable; töökindlaks is a grammatical variant used in various constructions to express reliability as a quality of a product, process, or service, or to indicate the aim of making something reliable. In everyday language, the term is used to describe both objects and organizations that can be trusted to perform as expected.
