Greenlight

Greenlight is a term used to denote permission to proceed, deriving from the green signal in traffic lights. It is widely applied in business, entertainment, and technology to indicate formal approval or go-ahead.

In business and project management, a green light is the formal approval to start or continue a project. This decision typically follows assessment of objectives, feasibility, budget, resources, risk, and expected benefits, and marks the transition from planning to execution.

In film, television, and other media, obtaining a green light means the project has secured financing and development resources and is approved to move into production or further development stages. The decision is a key milestone that signals commitment from studios, producers, or investors.

In software and information technology, green-lighting a release or feature indicates it has cleared required quality gates and is authorized for deployment to production. This can involve testing, security reviews, and compliance checks before customers or users gain access to the update.

Greenlight is also used as a corporate or brand name in various industries, including financial technology and media. The name conveys the notion of approval, progress, and the ability to move forward, and is adopted by multiple companies and products.

Overall, greenlight remains a versatile term for authorization and momentum across disciplines, contrasting with red light (stop) and yellow light (caution).
