Feature flags, also known as feature toggles, are a powerful tool in software delivery that provide granular control over releases, benefiting various departments within an organization, including engineering, sales, support, and management. They enable engineering teams to deliver 66% more features per application annually by lowering overhead and increasing velocity, while also helping product managers control releases and coordinate launch timings. Beyond engineering, feature flags offer sales and support teams the ability to manage betas and new features and track user interactions, while management gains improved visibility and governance capabilities. The use of feature flags extends across the entire software delivery lifecycle, from CI to CD, enhancing governance and standardization, and enabling the creation of comprehensive business intelligence dashboards. Feature flags are recommended for widespread organizational adoption to maximize their impact on software delivery and customer experience.
