Accessibility (often abbreviated as a11y) is the practice of designing and developing user interfaces that can be used by people with disabilities. This includes visual, auditory, motor, and cognitive impairments. It ensures equal access and opportunity for all people to interact with information and functionality.

Agentic AI refers to artificial intelligence systems capable of autonomous action to achieve defined goals. Unlike passive models that just respond to prompts (chatbots), agentic systems can plan workflows, use tools (APIs, browsers, CLIs), and execute multi-step tasks with minimal human intervention.

An umbrella term for a collection of frameworks and techniques that together enable teams and individuals to work in a way that is typified by collaboration, prioritization, iterative and incremental delivery, and timeboxing. There are several specific methods (or frameworks) that are classed as Agile, such as Scrum, Lean, and Kanban.

A software program that is designed to perform a specific function directly for a user or, in some cases, for another application program. Applications may be custom-developed or Commercial Off-The-Shelf (COTS) software.

The fundamental concepts or properties of a system in its environment embodied in its elements, relationships, and in the principles of its design and evolution. It provides a blueprint and roadmap for the development and deployment of systems.

Artificial Intelligence (AI) is the simulation of human intelligence processes by computer systems. These processes include learning (the acquisition of information and rules for using it), reasoning (using rules to reach approximate or definite conclusions), and self-correction.

The ability of an IT service or other configuration item to perform its agreed function when required. Availability is usually calculated as a percentage. It is often measured by the mean time between failures (MTBF) and mean time to restore service (MTRS).
