What Is Agile?

Agile is a framework that allows teams to work iteratively. It helps to ensure that each feature is in line with business and stakeholder goals, feasible to produce and meets user needs.

It also focuses on communication and collaboration. It supports teams to deliver a working solution to customers in short iterations, using tools like Scrum and XP.

Agile Software Development Lifecycle

The first phase of the Agile software development lifecycle is the iteration, also known as construction. This tends to be the longest stage as it is during this period that the bulk of the work will take place. During this iteration, developers will collaborate with UX designers to combine all product requirements and customer feedback, then turn the design into code. The aim is to build the bare functionality of the product by the end of the first iteration, or sprint. Later iterations can add additional features and tweaks.

One of the key principles of Agile is promoting transparency. This includes making sure that all team members and stakeholders have access to project status reports, roadmaps, and performance metrics. It also involves providing clear communication channels and collaboration tools.

Pair programming is an Agile practice that focuses on sharing knowledge and improving productivity by encouraging collaboration between team members. It’s a great way to promote better designs and fewer bugs, and it’s especially effective when used in combination with Test-Driven Development (TDD). This process involves turning requirements into test cases and improving the software until it passes all of these tests.


The agile scrum methodology is used by companies of all sizes to increase collaboration and efficiency on project-based work. It is a flexible process that allows teams to adapt to changes in requirements and customer demands. Scrum also supports teamwork and high-quality results.

Developers follow a set of rules to create working software incrementally in fixed-length increments called sprints. During each sprint, the development team works on one feature or piece of functionality, and the product owner and stakeholders examine the results after each sprint.

The agile scrum process eliminates the need for lengthy development cycles by breaking projects into small, functional units. It also allows the team to receive feedback from customers and make changes in the next sprint. Moreover, it allows developers to avoid overworking. This method reduces waste by focusing on the most valuable features and encourages collaboration between team members. Scrum also requires that teams use a tool such as Jira to track their progress.


Like the other Agile development frameworks, XP has its own set of guiding values and rules. These include continuous testing, short development cycles (also called iterations), delivering working software to customers, and face-to-face communication among team members. It also encourages teams to use refactoring to improve the quality of their code.

Unlike traditional Waterfall delivery methods, XP emphasizes customer feedback and iterative changes to the application’s scope of work. This approach can result in more efficient development, lower project costs, and improved user satisfaction.

During each iteration, developers work on user stories that have been prioritized and defined by the customer. The process includes weekly cycles, in which the team meets with the customer and selects the stories to deliver during that week. The team then produces running, tested features by the end of the week. The XP process also requires developers to perform the majority of their work in pairs and to focus on creating simple designs.


Feature Driven Development (FDD) is an Agile methodology that can be used by teams with varying levels of experience. It is a structured framework with five processes that support the delivery of software features. It is particularly useful for larger projects with a lot of team members and it is easy to manage as each build step is separated into its own short iteration.

This approach focuses on creating functional software and reducing risk, rather than on building complete end-to-end solutions. It also focuses on achieving customer satisfaction through frequent delivery and continuous improvement.

FDD requires a high level of collaboration and communication between team members. The development process is based on the principle that each individual should focus on his or her specific area of responsibility, such as visual designers working on UI components and programmers focusing on coded elements. It also aims to reduce the amount of technical documentation produced by teams. This approach allows teams to make decisions faster and improve productivity.
