Gemba walks, … Eliminate the need for inspection on a mass basis by building quality into the product in the first place.” It’s much cheaper to fix problems and defects if we find them immediately—ideally before they are ever checked into version control, by running automated tests locally. Each code merge to … We may also share information with trusted third-party providers. A pillar of modern application development, continuous delivery expands upon continuous integration by deploying all code changes to a testing environment and/or a production environment after the build stage.
