The general term “Agile” represents a variety of methods and practices, this is why it’s considered a so called “umbrella term”. Agile is a mindset, and this means that there is no a one-size-fit-all solution.
What all the Agile Methodologies or approaches have in common are the 12 Agile principles, listed in the Agile Manifesto:
- Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.
- Welcome changing requirements, even late in development. Agile processes harness change for the customer’s competitive advantage.
- Deliver working software frequently, from a couple of weeks to a couple of months, with preference to the shorter timescale.
- Business people and developers must work together daily throughout the project.
- Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.
- The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.
- Working software is the primary measure of progress.
- Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.
- Continuous attention to technical excellence and good design enhances agility.
- Simplicity — the art of maximizing the amount of work not done — is essential.
- The best architectures, requirements, and designs emerge from self-organizing teams.
- At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.
How is SCRUM related to Agile?

Scrum method was originally formalized for software development projects, but it works well for any complex, innovative scope of work. Scrum is an iterative software development model used for product development (different than project management).
