What is Agile software development?

Agile software development involves following a set of methodologies that govern how you and your team should work for better agility and maximum efficiency.

To understand the history of the Agile methodology, you have to go back to traditional software development methodologies like Waterfall. These relatively rigid and inflexible frameworks limited the ability of software teams to respond to changes in market conditions or client expectations.

Other drawbacks of traditional methodologies included limited client involvement and a longer time to market. Many in the industry saw a need for new methodologies to address the limitations of traditional frameworks.

In 2001, a team of software developers met to find a solution to different software development problems. In the end, they agreed on what they drafted the Agile Manifesto, which is based on four primary values:

1. Responding to change over relying on a plan
2. Customer collaboration over contract negotiation
3. Working software over comprehensive documentation
4. Individuals and interactions over processes and tools

The Agile methodology framework then evolved further to cover the following twelve principles:

1. Software teams and relevant stakeholders must collaborate throughout the project.
2. The team must create time to review and reflect on the project’s progress. The team should quickly adjust and align its operations with set standards in case of deviation.
3. Software teams should be self-organizing, which allows them to work under minimal supervision.
4. Adapting simplicity can help improve the amount of work done.
5. Adherence to good design and technical excellence facilitates business agility.
6. Embracing Agile and consistent processes can lead to sustainable development.
7. A working software product is an accurate measure of progress.
8. Face-to-face communication stands as the most effective communication method.
9. Motivated individuals can facilitate project success. Managers are encouraged to give team members all the support they need to boost productivity.
10. Continuous delivery of working software is achieved through a preference for the iterative approach and smaller increments.
11. There is a quick adaptation to change at any stage of development.
12. Customers should be offered early and continuous delivery of software.

Agile methodologies

There a number of Agile methodologies. While each emphasizes a different aspect of production, they  are all built on the same principles that emphasize teamwork and collaboration, fast adaptation to change, customer involvement, and effective communication. Below are some popular software development methodologies:

• Scrum. The Scrum methodology enables teams to deliver value in incremental steps. It’s built on three primary pillars: transparency, adaptation, and inspection. Scrum teams should be able to respond quickly to change. Key components of the Scrum methodology include the Scrum Master (facilitator of the entire Scrum process), Product Owner (develops and communicates product goals), and Sprints (covering the work necessary to achieve a product goal).
• Kanban. The Kanban methodology helps to visualize work processes, allowing teams to track progress and manage workflows easily. Work items are placed on Kanban boards, which enhances transparency by enabling all team members to monitor the project’s progress.
• Extreme Programming (XP). Extreme Programming requires software development teams to adhere to values like simplicity, courage, communication, respect, and feedback. Extreme Programming is for situations in which software requirements change often, available technology supports automated tests, and risks are associated with new technology.
• Lean Software Development. The Lean Agile-based methodology focuses on building efficiency and minimizing waste. Teams must also adhere to lean principles like respecting people, building quality, creating knowledge, deferring commitment, and delivering minimum viable products quickly. Lean software development also advocates for continuous improvement, which can help teams enhance product quality in the long run.
• Feature-Driven Development (FDD). FDD focuses more on rapidly developing software features—making it quite suitable for large and complex software projects. FDD also encourages client involvement and regular task reviews to ensure the team meets set goals and delivers value to customers.

Agile practices

Agile software development revolves around the following practices:

• Iterative development. The iterative process involves releasing a product in a series of steps, each resulting in a more refined product. User feedback is collected at the end of each stage, allowing teams to implement incremental improvements.
• User stories. Agile methodologies focus on enhancing customer involvement and satisfaction. Through user stories, software teams can understand the required features and functionality to satisfy customer needs and requirements.
• Stand-ups and sprint planning. Agile teams hold regular stand-ups and meetings, where they engage in sprint planning and role assignment. Such stand-ups hold Agile teams together, keeping them aligned for better collaboration.
• Retrospectives. Retrospectives allow Agile teams to meet and review the project’s progress and past activities. Through these meetings, software teams can identify mistakes and cases where they deviated from established standards and work on correcting them, paving the way for continuous improvement.
• Pair programming. As the name implies, pair programming involves two team members—one acting as the “driver” while the other as a “navigator”—working together to design, code, and test products. As a result, the pair programming methodology leads to better knowledge transfer between senior and junior developers and facilitates improved quality assurance.

Tools and techniques

Agile software development requires a number of different tools to facilitate productivity and effective workflow management. Some standard Agile tools and techniques that teams use include:

• Sprint backlogs and product backlogs. Product backlogs highlight the new features and items that should be integrated into a specific product. At the same time, the sprint backlog includes tasks that should be performed to achieve a specific product goal. Both sprint and product backlogs allow teams to prioritize tasks, deliver minimum viable products faster, and improve them incrementally.
• Agile frameworks. Apart from popular Agile methodologies like Scrum, software teams can also use Agile-based frameworks like Scaled Agile Framework (SAFe), Large Scale Scrum (LeSS), and Disciplined Agile (DA) to manage workflows.
• Workflow and automation. By embracing automation, Agile teams can experience improved efficiency, better decision-making, and fewer errors in their work. Automation can also help with repetitive and monotonous tasks, allowing the team to focus more on creative activities—streamlining the Agile process in the long run.
• Continuous integration (CI) and continuous delivery (CD). Agile software development emphasizes CI and CD efforts. Rather than teams trying to create a perfect product at once, they can push a minimally viable one and continuously improve upon it. This strategy leads to better software quality and enhanced workflow efficiency.

Benefits of Agile software development

From improved customer satisfaction to faster product delivery, we’ll explore the benefits you stand to gain by adopting Agile software development.

Enhanced customer satisfaction

Agile methodologies are designed to assist teams in meeting business needs effectively. Specifically, these methodologies encourage software teams to deliver working products in shorter cycles, meaning customers can interact with a product faster. The short cycles also allow software teams to collect valuable feedback about the product, which they can use in their continuous improvement efforts.

Agile software development also allows teams to be highly adaptable to change. This flexibility allows customers to easily change product requirements—in line with changing market conditions. Plus, Agile methodologies advocate for transparency and openness, meaning customers can access important information for effective decision-making.

Improved product quality

Agile software development improves product quality by facilitating collaboration, flexibility, and continuous testing and feedback loops. Agile teams follow an iterative development model that allows them to push products to market faster and continuously improve them. Testing is done in each cycle or sprint, allowing teams to identify and correct errors early.

The Agile approach also encourages frequent feedback loops between customers, developers, and testers, which leads to a more refined product. Using automated tools also helps teams minimize errors in their development workflow, improving quality.

Higher team morale

Agile focuses on building self-organizing and cross-functional teams. Such teams work well under minimal supervision—and all team members’ voices are heard and their views respected. Allowing team members to control how they execute different tasks can make them feel valued, which leads to higher motivation.

Since Agile methodologies promote regular feedback cycles, different team members’ efforts can be recognized by customers, product managers, or even colleagues, boosting their morale. Plus, Agile encourages creating a supportive environment where individuals feel valued.

Increased flexibility and adaptability

Agile methodologies are designed to maximize flexibility and adaptability out-of-the-box. Software teams are required to be flexible and agile, ready to welcome changing requirements at any development stage. The ability to adapt quickly allows Agile teams to create software products that align with evolving market situations, enhancing customer satisfaction.

Faster time to market

Agile software development facilitates faster time to market through iterative development and continuous delivery. Instead of spending time documenting each phase of a single large product launch, Agile teams push minimum viable products and continuously improve them in the next cycles or iterations.

Agile vs. traditional models

Agile was preceded by traditional models like Waterfall, which required teams to follow a series of steps to complete a project. In the Waterfall methodology, teams can only move forward after completing previous steps. It suited teams working on small and well-documented software projects. Waterfall also required teams to define goals early and work on accomplishing them without any deviations.

While incredibly helpful, the Waterfall methodology had its limitations, including making teams rigid and unresponsive to change. End-user participation was also limited—meaning teams could develop products that didn’t satisfy clients. Testing was only done after project completion, and extensive revisions could lead to major delays.

Agile is a more modern methodology focusing on teamwork and collaboration, fast adaptation to change, continuous improvement,  and openness and transparency. It offers numerous benefits, including facilitating faster time to market, increased flexibility and adaptability, increased customer satisfaction, and better team morale.

Nevertheless, Agile has its cons, particularly when it comes to documentation. Since Agile teams are highly adaptable, tracking and documenting changes can be intensive and time-consuming. Agile also highly depends on client availability, which can be problematic when other activities hold up customers.

Overall, Agile is more beneficial in situations characterized by evolving project requirements or changing environments. The Agile methodology is also suitable for those looking to build cross-functional teams—and in projects requiring frequent deliveries and regular feedback.

How to implement Agile in your organization

Agile is a robust project management methodology that can help you build high-quality products, survive rapidly evolving situations, and satisfy clients. While there’s no single way to follow Agile practices, we’ll explain some steps to help you get started:

• Determine project suitability. While Agile fits many projects and situations, it may only work well in some areas. Analyze your project to determine how the methodology best fits your use case.
• Assess team capability. Though Agile facilitates the creation of cross-functional and self-managing teams, you must first ensure you have the required talent and skill sets to accomplish a project.
• Build an Agile mindset. Encourage team members to develop an Agile mindset, allowing them to collaborate, communicate efficiently, and respond faster to change. An Agile mindset requires them to embrace Agile principles like respecting others, innovation and creativity, and continuous improvement efforts.
• Work with an Agile coach or Scrum Master. Collaborating with Agile coaches can help you master Agile fundamentals quickly and apply them in your workplace.
• Establish clear roles and structure. Identify all roles needed to complete a project and ensure they’re assigned to the right team members.
• Organize regular meetings. Meet regularly with team members to discuss upcoming sprints and to review past activities. Such stand-ups can help you optimize your team’s performance.
• Gather appropriate tools. Adopting a number of different communication, project management, and collaboration tools can help the team work better and boost your productivity.
• Provide Agile training. Training team members on different Agile principles and fundamentals is necessary to help them develop an Agile mindset.
