Introduction

Agile methodologies are software development techniques based on software and management principles that have been distilled over the past few decades. The primary differentiating factor between Agile methodology and traditional software development methods is the fluidity that the Agile methodologies inject in all stages of software development.

Agile software development is an umbrella term that encompasses various development techniques and philosophies, however, there are certain core characteristics that all of these share. The key features of Agile development are that it is based on iterative and incremental development encouraging an evolution of the requirements and solutions. Agile software development teams also tend to be more fluid, self-organizing and are often cross-functional. Agile software development at the core of it, strives to break the rigid boundaries that traditional software development techniques introduce.

History and the Agile manifesto

Historically, software development has followed the waterflow model In the late 1990’s several methodologies began to get increasing public attention. Each had a different combination of old ideas, new ideas, and transmuted old ideas. But they all emphasized close collaboration between the programmer team and business experts; face-to-face communication (as more efficient than written documentation); frequent delivery of new deployable business value; tight, self-organizing teams; and ways to craft the code and the team such that the inevitable requirements churn was not a crisis.
