Agility is how one can think and act. Agile is a set of principles and values. It is about the people, their state of mind, the interaction and cooperation among them. It involves analysis,
clarity, and transformation. It doesn’t comprise any events, roles, or artifacts.
Several convenient development methods emerged along with the creation of the Agile Manifesto. All these development strategies are now jointly called “agile” techniques.
Agile includes four primary steps:
- Short cycles.
- Incremental and iterative delivery.
- Sudden failure.
- Providing the customers with timely delivery.
Below are the seven prominent Agile frameworks:
1. Scrum: It is one of the widespread agile methodologies which allows you to be more agile. It borrowed its title from the football scrum which in turn utilized as a metaphor for:
- Stand-up meetings take place every day.
- The scrum entangles short iterations. The major focus of each iteration is to deliver the working software which has been developed by the team.
- A Product Owner is authorized to review whether there is any backlog in products and sprints. It recedes under high priority.
- Scrum master’s role is to sustain the best practices of agile.
2. Extreme Programming (XP): It is a set of practices pursued by developers. Developers must have the potential to carry out these practices. A small portion of work is planned and built by the team in a short duration of one to four weeks of iteration. XP focuses specifically on the engineering practices that are expected to attain ultimate levels.
3. Rapid Application Development (RAD): This method has been defined by James Martin in the year 1991. RAD is the most common name given to a sequence of iterative and agile methodologies. RAD involves requirement gathering and analysis, designing, implementing, and testing phases. It iteratively creates versions and prototypes of functions that are increasing.
4. Dynamic Systems Development Method(DSDM): It is an incremental and iterative software development procedure of agile that is based on RAD. As there is no acceptable way between the RAD crews, this approach remains unstructured.
It has become very problematic to hire experienced practitioners of RAD as every organization has ascertained its framework, methods, and divided standards. DSDM came into existence as a solution to this crisis.
- It provides a framework of four stages:
- Business study and feasibility.
- Prototype iteration or functional model.
- Build and design iterations.
5. Unified Process (UP): It is a risk-centric and architecture-centric RAD approach. It is a highly tailorable incremental and iterative methodology that involves considerable
implementations. The four stages of UP are:
- Initial stage
- Elaboration stage
- Construction stage
- Transition stage
6. Lean Approach: This approach emerged in 1970 in the manufacturing enterprise. Tom Popendieck and Mary involved these precepts in the book lean development of software.
The focus of the Lean Approach is to deliver value to the buyers by terminating the waste involved in the process.
7. Kanban Board: This approach originated while implementing the Lean methodology. It was refined by David Anderson in the year 2010. Kanban is based on visualizing the workflow on a manual board. The issue prompting the problems is then addressed. This enables in balancing the team’s demands and improves the work in progress within the team.
The agile development methodology is the hot way to manage projects related to software development. It is the common term conveyed to a set of practices and methods. Solutions in agile are developed when there is a conspiracy between cross-functional and self-organizing teams.
