The first obstacle we reached when we were setting up our continuous delivery pipeline was figuring out which branch to continuously deliver. We changed our minds a few times before settling on a pipeline that would run all the code from the development branch. Except production, that is, which would deploy from master. This was always a bit confusing and didn't make a whole lot of sense. The idea with git flow is that master always represents production while develop represents the current state of development. The idea of continuous delivery, though, is to reduce the time between what master represents and what develop represents. In the ideal case, develop and master would converge. These worldviews clash quite spectacularly when tried to use in conjunction.

The iteration is a cornerstone of agile development. It provides a heartbeat for the team and its stakeholders, and a structure for various routine activities that help keep development work aligned with what the customer needs. However, the way many teams run their iterations creates serious pitfalls which can keep them from delivering software as effectively as they could.

The orthodox approach to the iteration is to treat it as a timebox for delivering a batch of stories, which is the approach most Scrum teams take with sprints (the Scrum term for an iteration). In recent years many teams have scrapped this approach, either using iterations more as a checkpoint, as many ThoughtWorks teams do, or scrapping them entirely with Kanban and Lean software development.

Togglz is an implementation of the Feature Toggles pattern for Java. Feature Toggles are a very common agile development practices in the context of continuous deployment and delivery. The basic idea is to associate a toggle with each new feature you are working on. This allows you to enable or disable these features at application runtime, even for individual users.
