Are you looking for a way to deliver software products faster, better and cheaper? Do you want to improve your customer satisfaction, team collaboration and project management? If so, you might want to consider adopting agile as your software development methodology.

agile foundations: principles practices and frameworks


In this article, we will explore the basics of agile software development, including its definition, benefits and challenges. We will also introduce the core principles, practices and frameworks that make up agile. By the end of this article, you will have a solid understanding of what agile is and how it can help you achieve your goals.

What is agile?

Agile is a set of values, principles and practices that aim to deliver software products in short, iterative cycles called sprints. Agile focuses on delivering value to customers by responding to their changing needs and feedback. Agile also emphasizes collaboration among cross-functional teams, self-organization and continuous improvement.

Why use agile?

Agile offers many advantages over traditional software development methodologies, such as waterfall, which follow a linear and sequential process. Some of the benefits of agile are:

  • Faster delivery: Agile allows you to deliver working software in weeks or months rather than years. This reduces the time to market and increases customer satisfaction.

  • Better quality: Agile ensures that the software meets the customer's expectations and requirements by testing and validating it throughout the development process. This reduces the risk of errors and defects.

  • Cheaper cost: Agile helps you save money by avoiding waste and rework. By delivering software incrementally, you can prioritize the most valuable features and eliminate unnecessary ones. You can also adapt to changing requirements and feedback without having to redo the whole project.

  • Higher engagement: Agile fosters a culture of collaboration and empowerment among team members, stakeholders and customers. By involving them in every stage of the project, you can leverage their skills, knowledge and feedback. You can also motivate them by giving them autonomy, ownership and recognition.

  • Continuous improvement: Agile encourages you to learn from your mistakes and successes by reflecting on your performance and processes regularly. You can then apply the lessons learned to improve your quality, efficiency and effectiveness.

How to adopt agile?

Adopting agile is not a one-time event but a journey that requires commitment, experimentation and adaptation. There is no one-size-fits-all approach to agile, as different teams and projects may have different needs and preferences. However, there are some common steps that can help you get started with agile:

  • Understand the agile values and principles: Before you dive into the agile practices and frameworks, you need to understand the underlying philosophy behind agile. The Agile Manifesto defines four core values and twelve principles that guide agile software development. You should familiarize yourself with these values and principles and align your mindset and behavior with them.

  • Choose an agile framework: An agile framework is a set of rules, roles and processes that define how to implement agile in a specific context. There are many agile frameworks available, such as Scrum, Kanban, XP and Lean. You should choose the one that best suits your project's scope, size, complexity and goals. You can also customize or combine different frameworks to fit your needs.

  • Form an agile team: An agile team is a small, cross-functional and self-organizing group of people who work together to deliver software products. An agile team typically consists of 5 to 9 members, including developers, testers, designers, analysts and others. You should select the team members based on their skills, experience and attitude. You should also define the roles and responsibilities of each team member and ensure that they have the necessary tools and resources to perform their tasks.

  • Plan an agile project: An agile project is a collection of user stories that describe the features and functions of the software product. A user story is a simple and concise statement that captures the user's need, goal or benefit from using the product. For example, "As a customer, I want to log in to the website using my email and password, so that I can access my account". You should create user stories based on the customer's feedback and prioritize them according to their value and urgency. You should also estimate the time and effort required to complete each user story and assign them to different sprints.

  • Execute an agile sprint: An agile sprint is a fixed-length period of time, usually 2 to 4 weeks, during which the team works on a subset of user stories and delivers a potentially shippable product increment. An agile sprint consists of four main phases: sprint planning, sprint execution, sprint review and sprint retrospective. During the sprint planning, the team decides what user stories to work on and how to accomplish them. During the sprint execution, the team develops, tests and integrates the software product using various agile practices. During the sprint review, the team demonstrates the product increment to the customer and collects their feedback. During the sprint retrospective, the team reflects on their performance and identifies areas for improvement.

  • Repeat and improve: An agile project is not a linear process but a cyclical one. The team repeats the steps of planning, executing, reviewing and improving until they deliver the final product that meets the customer's expectations and requirements. The team also monitors and measures their progress and quality using various metrics and indicators. The team continuously adapts to changing needs and feedback by adding, modifying or removing user stories from the backlog.

Agile Principles

As mentioned earlier, the Agile Manifesto defines twelve principles that guide agile software development. These principles are:

Customer satisfaction

The highest priority is to satisfy the customer through early and continuous delivery of valuable software.

Embrace change

Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage.

Deliver value frequently

Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.

Collaborate with stakeholders

Business people and developers must work together daily throughout the project.

Empower teams

Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.

Promote quality

The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.

Reflect and improve

Working software is the primary measure of progress.

User stories

User stories are short descriptions of what users want to do or achieve with the software product. They are written from the user's perspective and follow a simple format: "As a , I want to , so that I can ". User stories help capture the customer's needs and expectations in a clear and concise way. They also help prioritize, estimate and plan the development work.

Backlog management

A backlog is a list of user stories that represent the features and functions of the software product. A backlog is dynamic and evolving, as new user stories are added, modified or removed based on changing requirements and feedback. A backlog is managed by a product owner, who is responsible for defining, prioritizing and communicating the user stories to the development team.

Iterative development

Testing and feedback

Testing and feedback are essential parts of agile software development. Testing ensures that the software product meets the quality standards and user expectations. Feedback helps validate the customer's needs and satisfaction. Testing and feedback are performed throughout the development process, not just at the end. Testing and feedback can be done by various methods, such as unit testing, integration testing, acceptance testing, usability testing, user testing, etc.

Continuous integration and delivery

Continuous integration and delivery are practices that aim to deliver software products faster and more reliably. Continuous integration is the process of merging the code changes from multiple developers into a shared repository frequently, usually several times a day. Continuous delivery is the process of deploying the software product to the production environment automatically or with minimal human intervention. Continuous integration and delivery help reduce errors, bugs and conflicts in the code, as well as shorten the feedback loop and time to market.

Agile ceremonies

Agile ceremonies are meetings or events that facilitate communication, collaboration and coordination among the agile team members and stakeholders. Agile ceremonies include:

  • Daily stand-up: A short meeting, usually 15 minutes or less, where each team member shares what they did yesterday, what they will do today and any impediments they face.

  • Sprint planning: A meeting at the beginning of each sprint where the team decides what user stories to work on and how to accomplish them.

  • Sprint review: A meeting at the end of each sprint where the team demonstrates the product increment to the customer and collects their feedback.

  • Sprint retrospective: A meeting after each sprint where the team reflects on their performance and identifies areas for improvement.

Agile Frameworks

As mentioned earlier, there are many agile frameworks available that provide different ways of implementing agile in specific contexts. Some of the most popular agile frameworks are:


Scrum is a framework that focuses on delivering software products in fixed-length iterations called sprints. Scrum defines three main roles: product owner, scrum master and development team. The product owner is responsible for defining and prioritizing the user stories in the backlog. The scrum master is responsible for facilitating and coaching the development team and ensuring that they follow the scrum rules and values. The development team is responsible for developing, testing and delivering the software product. Scrum also defines four main ceremonies: sprint planning, daily stand-up, sprint review and sprint retrospective.


Kanban is a framework that focuses on visualizing and optimizing the flow of work in a system. Kanban uses a board with columns that represent different stages of work, such as to-do, in progress, done, etc. Kanban also uses cards that represent different work items, such as user stories, tasks, bugs, etc. Kanban helps limit the amount of work in progress (WIP) in each stage by setting WIP limits. Kanban also helps measure and improve the cycle time, which is the time it takes for a work item to move from one stage to another.

Extreme Programming (XP)

Extreme Programming (XP) is a framework that focuses on delivering high-quality software products through frequent releases and customer involvement. XP defines five core values: communication, simplicity, feedback, courage and respect. XP also defines twelve practices: user stories, planning game, small releases, simple design, test-driven development (TDD), pair programming, collective ownership, continuous integration, coding standards, metaphor, sustainable pace and on-site customer.

Lean Software Development

Lean Software Development is a framework that focuses on eliminating waste and maximizing value in software development. Lean Software Development is based on seven principles: eliminate waste, amplify learning, decide as late as possible, deliver as fast as possible, empower the team, build integrity in and see the whole.

What is the difference between agile and waterfall?

Waterfall is a traditional software development methodology that follows a linear and sequential process. Waterfall divides the project into distinct phases, such as requirements, design, development, testing and deployment. Waterfall assumes that the requirements are fixed and known upfront and that the product can be delivered in one go at the end of the project. Waterfall is suitable for projects that have clear and stable requirements, low uncertainty and high predictability.

  • Agile is a modern software development methodology that follows an iterative and incremental process. Agile delivers the product in short, frequent cycles called sprints. Agile assumes that the requirements are dynamic and evolving and that the product can be delivered in small pieces throughout the project. Agile is suitable for projects that have changing and complex requirements, high uncertainty and low predictability.

What are the benefits of agile?

  • Some of the benefits of agile are faster delivery, better quality, cheaper cost, higher engagement and continuous improvement.

What are the challenges of agile?
