Feature toggles (sometimes referred to as feature flags) are an engineering practice aiming to control application behavior without the need to deploy a code change. The behaviors that toggles can affect range from hiding under development features, limited feature release (canary) to a subset of users, or used to switch to fallback implementation in the event of a system issue, and more.

Continuous integration, continuous delivery, and continuous deployment implementations cover a wide range of automation possibilities for your software. This article will provide an overview of these three principles, the benefits they can bring to your engineering efficiency, and potential challenges.

Improve customer satisfaction and maintain an edge over competitors by getting cutting-edge features into production faster and with fewer defects with Continuous Software Development techniques. Continuous Software Development is a term applied to a set of incremental strategies that aim to reduce the delay between development and deployment of new features.

This is part 2 of the Disciplined Engineering series. It focuses on improving the confidence of the code produced by your team.
