Agile Principle 3: Frequent Delivery

Let's take a look at the third underlying principle of the agile manifesto:
"Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale."
What does that really mean? What are the implications for our daily business? Let's analyze this principle and see where this gets us.
  • "Deliver" - actually have something finished that is worth being given to the users.
    Values: Courage, Commitment
    Principles: Deliver as fast as possible
    Practices: Incremental Deployment, Small Releases, Sprint Review, Product Demonstration
  • "working software" - the results of our efforts must not be theoretical concepts or prototypes, but a functional software product the user is able to work with effectively
    Values: Focus, Commitment
    Principles: Quality
    Practices: Definition of Done, Acceptance Tests, Sprint Review, Product Demonstration
  • "frequently" - give an usable product more often to the users than just once at the end of the development project
    Values: Focus, Courage
    Principles: Frequent Delivery
    Practices: Incremental Deployment, Small Releases
  • "from a couple of weeks to a couple of months" - keep the iterations short so they are easily manageable and clearly arranged
    Values: Focus
    Principles: Deliver as fast as possible, Iterative
    Practices: Iteration
  • "with a preference to the shorter timescale" - create results early and often so the customer is able to react and decide quickly
    Values: Focus, Simplicity
    Principles: Iterative, Limit Work in Progress, Deliver as fast as possible, Eliminate Waste
    Practices: Incremental Deployment, Small Releases, Sprint Backlog, Iteration
There's not much to summarize here but to say it in two words, the third principle is about Frequent Delivery.
