What is Agile?
Agile is a mindset
It is not a tool , it is a mindset/philosophy, it allows us to embrace change throughout the process and adapt to the change so that we can deliver the product that the customer really wants and incorporate the new learnings into product design as quickly as we can.
Agile principles and values
Agile is usually defined by 4 values and 12 principles which were formulated by software engineers in 2001 and can now be found on https://agilemanifesto.org/ with translations on multiple languages. While a lot of those principles and values refer to software development, they can be applied to other industries.
4 values of Agile
Individuals and interactions over processes and tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan
12 principles of Agile
1. Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.
2. Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage.
3. Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.
4. Business people and developers must work together daily throughout the project.
5. Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.
6. The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.
7. Working software is the primary measure of progress.
8. Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.
9. Continuous attention to technical excellence and good design enhances agility.
10. Simplicity--the art of maximizing the amount of work not done--is essential.
11. The best architectures, requirements, and designs emerge from self-organizing teams.
12. At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.
So Agile is all about a mindset, but how we are going to apply Agile principles in real life? For this reason several frameworks have come out to help us to adjust Agile principles on our projects, such frameworks are:
