reliability
What It Means
Reliability means your AI system performs consistently and predictably over time, producing similar results when given the same inputs under similar conditions. It's about whether you can count on your AI to work the same way today as it did yesterday, and will tomorrow.
Why Chief AI Officers Care
Unreliable AI systems create operational chaos, erode user trust, and can lead to costly business decisions based on inconsistent outputs. Reliability directly impacts customer experience, regulatory compliance, and the ROI of AI investments since inconsistent performance makes systems unusable in production environments.
Real-World Example
A credit scoring AI that approves a loan application on Monday but rejects the identical application on Wednesday, despite no changes in the applicant's profile or market conditions, demonstrates poor reliability and could expose the bank to regulatory scrutiny and customer complaints.
Common Confusion
People often confuse reliability with accuracy - an AI can be reliably wrong, consistently producing the same incorrect results. Reliability is about consistency of behavior, while accuracy is about correctness of results.

Technical Definitions
NISTNational Institute of Standards and Technology
"Reliability refers to the closeness of the initial estimated value(s) to the subsequent estimated values."Source: OECD
"ability of an item to perform as required, without failure, for a given time interval, under given conditions. Note 1 to <system> definition: The time interval duration can be expressed in units appropriate to the item concerned (e.g. calendar time, operating cycles, distance run, etc.) and the units should always be clearly stated. Note 2 to <system> definition: Given conditions include aspects that affect reliability, such as: mode of operation, stress levels, environmental conditions, and maintenance."Source: ISO/IEC_TS_5723:2022(en)
"property of consistent intended behaviour and results"Source: aime_measurement_2022, citing ISO/IEC 22989
