A plethora of tools and technology are expanding at a rapid pace with the goal of assisting businesses in maximizing their company value. This is one of the primary reasons why companies are collaborating with IT outsourcing firms. Companies are also welcoming Agile technology with open arms. The rising popularity of this technology is justified as it lets organizations’ work in small increments and make changes quickly. It is a set of concepts used to project administration and software development. This strategy focuses on continuous testing and development for a specific business project’s whole Agile software development lifecycle. The goal of Agile consulting is to help teams achieve small, manageable goals rather than trying to make big changes, which has the benefit of providing customers with what they need easily without needing to set big, unachievable goals.
AGILE SOFTWARE DEVELOPMENT
Agile software development is a collection of methods and frameworks based on the Agile Manifesto’s basic ideas and ideals. When compared to other methodologies, agile methodology is one of the greatest ways of approaching software development company. One element that distinguishes the Agile technique is that it necessitates collaboration among team members. Furthermore, achievements are obtained by cross-functional, self-organizing teams collaborating. Pair programming, test-driven developing, stand-ups, planning meetings, and sprints are all examples of agile software development approaches. Agile differs from traditional software development methodologies in that it focuses on the people doing the job and how they collaborate. Engagement between self-organizing cross-functional groups using the best methods for their context leads to solutions.
AGILE DEVELOPMENT MODELS
The Iterative Waterfall model was once a popular way to finish a project. However, today’s developers face a number of issues when using it to create software. The key challenges were dealing with client modification requests during project development, as well as the significant cost and time necessary to make these changes. The Agile Software Development model was developed in the mid-1990s in order to overcome these drawbacks of the Waterfall model.
The basic purpose of the Agile methodology is to allow speedy project completion. Agility is essential to complete this challenge. Agility is accomplished by tailoring the workflow to the project and eliminating processes that aren’t required for the project. Anything that wastes time and energy is also avoided.
There are various development processes associated with the agile model. A few Agile SDLC models are given below:
- Scrum
- Extreme programming (XP)
- Feature-driven development
- Lean development
- Unified process
- Crystal
- Atern
Iterative development is used in the Agile methodology. Each incremental component is created iteratively. Each iteration is supposed to be short and manageable, and it should only take a few weeks to complete. One iteration is defined, built, and released to clients at a time. Iterative and incremental process approaches are combined in the agile paradigm. The following are the steps involved in agile SDLC models:
- Gathering requirements
- Analysis of Requirements
- Design \Coding
- Testing at the unit level
- Approval testing
ADVANTAGES OF AGILE MODEL:
- After each iteration, customer service personnel gain the notion of new software goods. As a result, he can easily adjust any need if necessary.
- When compared to developers working alone, pair programming produces well-written compact programs with fewer mistakes.
- It cuts the project’s total development time in half.
DISADVANTAGES OF AGILE MODEL:
- When a project is completed and the programmers are allocated to another project, maintaining the established project might become a difficulty due to a lack of sufficient documentation.
- Because there are no formal records, there is a misunderstanding, and crucial choices made at different stages might be misconstrued by different members of the team at any moment.
