What Is Agile Software Development?

Agile software development has emerged as one of the most popular software development methods in the industry over the years. Due to the benefits such as software development quality, flexibility in implementing changes, transparency in progress, and predictability in software development timeline and costs have made it increasingly popular. 

Apart from these, the Agile software development method has a success rate of 88.2%, which showcases its capability. In this blog, we will be discussing Agile software development, its benefits, methodologies, associated challenges, and more.

Definition of Agile Software Development

Agile software development is a set of software development methodologies that are focused on flexibility, efficiency, and collaboration and enable the development teams to create quality products.

What Makes Agile Different From Traditional Software Development?

Iterative & Incremental Development

Agile methodologies focus on iterative and incremental development, which allows the software to be developed in small pieces and delivered to the client in short cycles. This allows the development team to collect and input the frequent feedback and also enables them to adapt to regularly changing requirements.

Client Collaboration

The main priority of Agile methodologies is client collaboration during the development process. The process includes regular communication with the client to identify and assess their needs and requirements to make sure that the developed software is up to their expectations.

Cross-Functional Teams

Agile methodologies enable cross-functional teams to collaborate and ensure all the involved members are on the same page in identifying and understanding the project goals and requirements.


Agile methodologies offer the development teams flexibility and adaptability to balance the continuous changes in the project requirements. 

Working Software

Agile methodologies prioritize the delivery of working software over extensive planning and documentation, which makes the process way easy for the teams.

Continuous Improvement

Agile methodologies prefer continuous enhancement and improvement via using retrospectives and regular updates from clients. In this way, the development teams can discover the sections for improvement and implement changes to their processes in an attempt to enhance efficiency and quality.

12 Principles of Agile Software Development

  • Secure client satisfaction via early and regular delivery
  • Acknowledge and accept changing requirements, even if late in development
  • Always deliver working software
  • Collaboration between developers and business people during the course of the project
  • Develop the projects around inspired individuals and offer them the backing they need
  • Utilize fact-to-face communication when possible
  • Working software is the first foremost measure of progress
  • Sustainable development, where a constant pace is maintained
  • Continuous focus on technical excellence and quality designs improves agility
  • Simplicity is necessary
  • Self-organizing teams offer greater value
  • Regular reflection on the work and adaptation to be more effective is required

Different Agile Software Development Methodologies

1. Scrum

Scrum is one of the Agile software development frameworks, and collaboration, self-organization, and iterative development are the areas it mainly focuses on. This framework includes a series of short development cycles, referred to as ‘sprints’, during these sprints the development teams build and deliver working software.

Advantages of Scrum

  • Encourages collaboration and communication among team members
  • Establishes flexibility and adaptability to continuous changes in requirements
  • Prioritizes the delivery of working software

2. Kanban

Kanban is a visual Agile methodology that focuses on the flow of work and the minimization of waste. This methodology involves visualizing the entire development process on a Kanban board, restricting the work in progress, and regularly enhancing the process.

Advantages of Kanban

  • Offers clear visual representation of the workflow
  • Enable the teams to mark out waste in the development process
  • Enables teams for frequent delivery of small segments of work

3. Extreme Programming (XP)

XP is another Agile methodology that focuses on continuous delivery, quality testing, and client input or feedback. This methodology includes practices like pair programming, test-based development, and regular integration to make sure high-end software products are developed.

Advantages of Extreme Programming (XP) 

  • Offers a perfect framework to deliver high-end software solutions
  • Prioritizes regular delivery, quality testing, and client input or feedback
  • Offers a clear focus on client satisfaction and offers value

4. Lean Software Development

The Lean software development methodology prioritizes minimizing waste and maximizing value. This methodology involves practices like eliminating non-value-added tasks, creating a pull system, and delivering the software as quickly as possible.

Advantages of Lean Software Development

  • Prioritizes waste reduction and offers maximum value 
  • Enables continuous enhancement of the development process
  • Provides an accurate framework to deliver high-quality software

Challenges Associated with Agile Software Development

Although Agile software development offers significant benefits and scopes to the development teams it also brings a few critical challenges.

  • Resistance to Change

Opting for Agile methodologies requires a critical shift of mindset as well as culture. There may be a few team members who will be reluctant to adopt the changes in their working style.

  • Lack of Clarity

As Agile methodologies require a high standard of collaboration and communication it can sometimes cause a lack of clarity, which will lead to misjudgments and confusion within the team.

  • Over-Reliance

In certain Agile methodologies, namely Scrum, product owners play a vital role in determining and prioritizing the product backlog. But in case the owner is unavailable or does not have the required knowledge, the development team will surely struggle to move forward.

  • Difficulty in Time & Cost Estimation

As Agile software development prioritizes flexibility and adaptability against strict timeframes and budgets, the accurate estimation of development time and cost becomes challenging.

  • Lack of Structure

Agile software development is comparatively less structured than traditional software development processes. So, the correct management of large and complex projects becomes highly difficult.

  • Lack of Documentation

As Agile software development emphasizes delivering working software over detailed documentation, development teams can find it challenging to manage and transfer the key concepts within the team.

The Final Thoughts

Agile software development has revolutionized the traditional approaches to software development by providing teams with a fresh perspective on project management. Agile offers several benefits, such as faster delivery of working software, increased collaboration, and adaptability to change. However, Agile is not free from challenges, and teams need to address these challenges to maximize the benefits.
