This talk shows Best Practices that can be used to develop application in an agile and feature driven workflow. Companies like flickr use this development process internally and even Martin Fowler defined a part of the process as “FeatureToggle”. In the talk I will start with the definition of feature tasks and what steps and methods are needed to define them. Next to this an application is shown that was developed by the use of FeatureToggles. Here different architecture approaches in Java will be shown. Next to the architecture of an application the development workflows must be changed to create applications in a feature driven way, too. In some examples best practices to handle the new workflows will be shown. Methods and tools like the GitFlow, GitLab, the Java Togglz API and Jira will be shown in this talk.
