An extension of the principles behind continuous integration. It entails that the code is always in a state in which it is deployable. This practice leans heavily on the automation of the testing and delivery processes, to ensure that these happen without any hiccups. The testing happens in stages, where if the code passes one stage of tests, it automatically passes on to the next stage, and so on and so forth until the application is ready for deployment.

An extension of continuous delivery, where the application is not just delivered but also automatically deployed so that it runs on the production infrastructure.

By making it a practice to integrate code into the main branch of a shared repository as early and often as possible, continuous integration minimizes the cost of integration in a build process and allows for more frequent and automated testing. By kicking off automated tests as soon as a developer merges a new code, test suites can be run to check whether any new integration errors were introduced.

Digital manufacturing is considered "manufacturing's next act". It is part of the new wave of industry 4.0, where CAD design, digital manufacturing, robotics, sensors and data & analytics are combined to redefine industrial production. Digital manufacturing defines the process of designing a product or prototype in CAD, and then creating the physical version via additive manufacturing, laser cutting or CNC.

This is a characteristic of quality in use of the ISO25010 standard.

TMap HD describes the five elements of quality-driven testing. These elements have two goals. At the one hand they are elements of the development of the quality- and testing profession.

Machine intelligence (MI) is a unifying term for what others call machine learning (ML) and artificial intelligence (AI). We found that when we called it AI, too many people were distracted by whether certain companies were "true AI", and when we called it ML, many thought we weren't doing justice to the more "AI-esque"-like aspects, such as the various flavors of deep learning. So, machine intelligence is a term that combines "artificial intelligence", "machine learning" and other related terms.

Machine learning is one of the ways to achieve artificial intelligence. It contains different algorithms – each with its own strengths and weaknesses. These algorithms are often grouped into three categories: supervised learning, unsupervised learning, reinforcement learning.

A review is a static test of a product. This means testing without "running" software or systems. There are various review types (also called static test techniques), such as: walkthrough (transfer of knowledge and exchange of visions), technical review (e.g. selecting solution direction/alternative), management review (e.g. determining project status), informal review (review by colleagues with no formal process), and inspection (the most thorough review technique that establishes the quality level of a product).
