Adaptive Software Development Introduction - Adaptive software development

What is Agile?

The person with the trait of moving quickly and easily or thinking and acting quickly and clearly is considered to be agile. In terms of business, the different ways of planning and performance of the work with the assumption that changes as required is an essential part of the job. In other words, business agility implies that a business is always ready for taking the changes in the market and acting accordingly.

The ability to respond to the changes is defined as “agile” in terms of software development. The changes may be either from requirements, technology or people.

What is Agile Manifesto?

In 2001, a tem of the software developers developed Agile Manifesto. This manifesto highlights the importance of the development team by facilitating the requirements for accepting the changes and customer involvement.

The Agile Manifesto value:

  • Individuals and interactions over processes and tools.
  • Working software over comprehensive documentation.
  • Customer collaboration over contract negotiation.
  • Responding to change over following a plan.

That is, while there is value in the items on the right, we value the items on the left more.

What are the characteristics of Agility?

The characteristics of Agility are as follows:

  • The main focus area of Agility in Agile Software Development is the team culture including multi-discipline, cross-functional empowered teams and self organizing.
  • It fosters shared responsibility and accountability.
  • Effective communication and continuous collaboration is facilitated by Agility.
  • Delays and wait times are avoided by the whole-team approach.
  • Quick feedback is ensured by frequent and continuous deliveries and which in turn facilitate in aligning the team requirements.
  • Different perspectives are combined timely in implementation, fixing of the defect and accommodating the changes by Collaboration.
  • Progress is constant, sustainable, and predictable emphasizing transparency.

What are the different Agile Methodologies?

Some of the methodologies of Agile include Rational Unified Process, Scrum, Crystal Clear, Extreme Programming, Adaptive Software Development, Feature Driven Development, and Dynamic Systems Development Method (DSDM). The tutorial only focuses on the methodology – Adaptive Software Development.

What is Adaptive Software Development?

In order to build complex systems, Adaptive Software Development is used as a technique which focuses on collaboration and learning. Adaptive Software Development is evolved from the best practices of Rapid Application Development (RAD) and Evolutionary Life Cycles. In complex environment and in the context of complex systems, Adaptive Software Development is more towards adaptive practices than deterministic practices. It is slowly extended and include adaptive approaches for management replacing planning.

ASD Life Cycle

In the words of Jim Highsmith, An evolutionary model with different phases such as Speculate, collaborate, learn is Adaptive Software Development, that reflect the unpredictable realm of the increasingly complex systems. Adaptive development can be studied in two ways. Firstly, the determinism is replaced with emergence and secondly, It goes beyond the changes in the Life Cycle towards change in the management style.
