I think that probably most development teams describe themselves as being “agile” and probably most development teams have standups, and meetings called retrospectives.There is also a lot of discussion about “agile”, much written about “agile”, and there are many presentations about “agile”. A question that is often asked is what comes after “agile”? Many testers work in “agile” teams so this question matters to us.
Xamarin is an open-source framework that offers cross-platform application development using the C# programming language. It helps to simplify your overall development and management of cross-platform software applications.
Agile software development stems from a philosophy that being agile means creating and responding to change swiftly. Agile means having the ability to adapt and respond to change without dissolving into chaos. Being Agile involves teamwork built on diverse capabilities, skills, and talents. Team members include both the business and software development sides working together to produce working software that meets or exceeds customer expectations continuously.
Agile project management is a great alternative to traditional methods, to address the customer’s needs and the delivery of business value from the beginning of the project. This blog describes the main benefits of Agile for both the customer and the business.
