Agile

Agile is a methodology for developing software and agile approaches allow teams to take an iterative approach towards building a product. 

So there's four key things in agile manifesto. They are individuals and interactions over processes and tools, working software over comprehensive documentation. Customer collaboration over contract negotiation and responding to change over following a plan.

So agile encourages collaboration between different team members. For testers, that means that we engage with our teams earlier in the project. And teams can regularly feed back to users to ensure that they are on the right path. And another big benefit agile is agility being able to adapt to change.

Agile is a principle and not just a series of activities such as planning and a retrospective. And it requires a team to be mature and regularly communicate and collaborate with one another. And a team not making any noise as an agile.
