Why do continuous delivery?
From: cd trends in financial services, CA, 2017

Continuous delivery is a DevOps software
development practice where code changes
are automatically built, tested, and prepared
for a release to production.
Amazon web services

The term "Continuous Delivery" ("CD") represents a set of principles
and practices in growing use in software development to improve the
process of software delivery. Techniques such as automated
testing, continuous integration and automated deployments allow
software to be developed to a high standard and easily packaged and
deployed to test environments, resulting in the ability to rapidly,
reliably and repeatedly push out enhancements and bug fixes to
customers at low risk and with minimal manual overhead.
Wikipedia, 2011

Continuous Delivery (CD) is a set of practices and principles
in software engineering aimed at, building, testing, and
releasing software, faster and more frequently. These
principles help reduce the cost, time and risk of delivering
changes, and ultimately value, to customers by allowing for
more incremental changes to applications in production.
Wikipedia, 2017
