Agile Values and Principles: From Manifesto to Practice

Introduction

This is the second article in a series of articles on Agile. In the previous article, we explored the basics of Agile, including its history, core values, and principles that have made it so popular in modern software development teams. Now, to successfully implement Agile practices, it’s crucial to gain a deeper understanding of its key principles. These principles guide how teams should approach their work practically and interact with their surrounding environment. In this article, we will also explore major Agile frameworks that help translate these principles into real-world projects.

Agile Values and Principles: Their Importance and Practical Application

Agile, as an approach, is founded on four core values and twelve principles articulated in the Manifesto for Agile Software Development. These values and principles serve as a guide for teams, helping them remain flexible, adaptable, and focused on delivering customer value.

Let’s take a closer look at their essence and practical application.

Four Key Agile Values

The values of the Agile Manifesto are the fundamental pillars that shape the priorities and methodologies of Agile teams. Each value acts as a foundation for the practical principles of Agile and helps teams concentrate on what truly matters — creating customer value. Here are the core values:

Individuals and interactions over processes and tools

In Agile, while processes and tools are important, they are secondary to the people involved and their interactions. This means that successful collaboration and effective communication take precedence over strict adherence to procedures.

Agile teams organize their work around face-to-face meetings, dialogs, and interactions, which facilitate a deeper understanding of tasks and faster problem-solving.

Working software over comprehensive documentation

While documentation has its place, it should not impede the creation of functional products. The primary objective of Agile is to swiftly deliver working solutions, rather than spending excessive time on detailed documentation.

Agile teams focus on the continuous delivery of functional software, utilizing documentation only when absolutely necessary.

Customer collaboration over contract negotiation

Agile emphasizes close and ongoing collaboration with the customer to ensure the product meets their needs and can adapt to changing requirements.

Rather than strictly following contractual obligations, Agile teams are flexible in adapting to changes and maintaining an open dialog with the customer.

Responding to change over following a plan

Agile embraces change as an inevitable part of any project and views it as an opportunity to gain a competitive advantage. Plans can be adjusted as new information arises.

Agile projects are structured in short iterations, allowing teams to quickly respond to changes and adjust their actions accordingly.

Twelve Agile Principles

Agile principles form the foundation for an efficient and flexible development process. They offer specific approaches that help teams adapt to changes, ensure high product quality, and meet customer needs. Each of these principles reinforces the four core values of Agile, guiding teams to create an adaptive, productive, and customer-focused development process. Let’s take a closer look at how these principles manifest in practice and contribute to the success of projects.

Principle 1. Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.

The primary goal of Agile is to meet customer needs through the early and regular delivery of working software. It is not just about building the product but ensuring it aligns with the customer’s expectations, achieved through continuous updates and improvements.

Agile teams break down work into short iterations, at the end of which they present a working product to the client. This allows the client to evaluate progress and provide feedback early, minimizing risks and increasing satisfaction.

Principle 2. Welcome changing requirements, even late in development. Agile processes harness change for the customer’s competitive advantage.

Agile emphasizes the importance of being prepared for change. Even if requirements change late in the development process, it is welcomed because it can lead to a more valuable product.

Agile teams work closely with customers and other stakeholders to quickly adapt their plans to new requirements. This makes development processes agile and resilient in the face of change.

Principle 3: Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.

Agile focuses on frequent delivery of working software, which allows teams to receive feedback from the customer and adjust their work direction accordingly.

Teams organize their work into short iterations (sprints) lasting from one to several weeks, at the end of which they present a new version of the product to the customer. This approach maintains continuous progress and customer engagement.

Principle 4: Business people and developers must work together daily throughout the project.

Close collaboration between business stakeholders and developers is essential for project success. It promotes a better understanding of project goals and enables the prompt resolution of emerging issues.

The business representative should actively interact with the team, providing regular feedback. In practice, this is reflected in frequent meetings with the team, regular product demonstrations to the customer, and joint discussions of priorities. Such collaboration allows for timely adjustments to requirements and ensures that the final product aligns with customer expectations and business goals.

Principle 5: Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.

Agile projects are organized to involve motivated individuals who are trusted to get the job done. Teams are provided with the necessary support and resources to successfully accomplish their tasks.

Agile teams consist of professionals with a high level of self-organization. They are trusted to choose their methods of work and make decisions, which enhances their engagement and accountability for the results.

Principle 6. The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.

Face-to-face communication is the most effective way to convey information within Agile teams. It minimizes misunderstandings and speeds up the process of idea exchange.

In Agile teams, in-person meetings and face-to-face communication are prioritized to ensure more productive interactions and quicker issue resolution.

Principle 7. Working software is the primary measure of progress.

Project progress is assessed by the useful functionality and quality of the working software, rather than the amount of documentation or completed tasks.

Agile teams focus on developing working software that can be demonstrated and evaluated. This helps to more accurately measure the actual progress of the project.

Principle 8. Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.

Agile supports stable and sustainable project development. The pace of work should be consistent and should not lead to team overload and burnout.

Teams organize their work to avoid sudden workload spikes. They plan iterations in a way that maintains a steady pace, contributing to the long-term success of the project.

Principle 9. Continuous attention to technical excellence and good design enhances agility.

Technical excellence and quality design are the foundation of flexibility and adaptability in Agile teams.

Teams strive to build high-quality, well-designed software. This includes continuous improvement of architecture and development practices to ensure the product’s longevity and scalability.

Principle 10. Simplicity–the art of maximizing the amount of work not done–is essential.

Agile supports the principle of minimizing unnecessary work to focus on what is truly important.

Teams prioritize tasks, eliminating those that do not add value to the product. This allows them to focus on the essential aspects and avoid wasting time on unnecessary activities.

Principle 11. The best architectures, requirements, and designs emerge from self-organizing teams.

Agile supports self-organizing teams because they adapt to change faster and create better solutions.

Agile teams have the autonomy to make decisions and organize their work. This allows them to adapt to changes quickly and develop innovative solutions that meet current requirements.

Principle 12. At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.

Agile teams conduct regular retrospectives to assess their work and make improvements to processes.

Retrospectives are held at the end of each iteration. The team analyzes what went well and what could be improved, and then optimizes their approach in the next sprint, fostering continuous improvement and efficiency.

Major frameworks in Agile

There are several popular frameworks in the Agile environment that help teams effectively incorporate Agile values and principles into their work. Each of these frameworks offers a unique set of practices and approaches aimed at achieving flexibility, adaptability, and increased team effectiveness. It is important to understand the key differences and features of each framework in order to choose the best fit for a particular project or team.

Below, we will examine three of the most common Agile frameworks: Scrum, Kanban, and Extreme Programming (XP).

Scrum

Scrum is one of the most popular and widely used Agile frameworks designed for managing complex projects. The foundation of Scrum lies in working in short, fixed iterations called sprints, which typically last one to four weeks. Each sprint culminates in the creation of an increment that meets certain “Definition of Done” (DoD) criteria.

Scrum includes three key roles:

• Product Owner: Responsible for managing the product backlog, prioritizing tasks, and maximizing value to the customer.
• Scrum Master: Helps the team adhere to Scrum principles and practices, removes obstacles, and ensures the team works effectively.
• Developers: A cross-functional group of specialists who organize their work independently and are responsible for creating increments.

Key Scrum artifacts include:

• Product Backlog: An ordered list of all tasks and requirements that must be completed to achieve the product goal.
• Sprint Backlog: A set of tasks selected from the Product Backlog to be completed in the current sprint to achieve its goal.
• Increment: A completed and functional product or part of a product ready for potential release.

Scrum is ideal for projects that require high flexibility and the ability to adapt quickly to changes. This framework is widely used in software development, but its principles can be adapted for project management in other areas as well. Scrum encourages frequent engagement with stakeholders, process improvement based on regular retrospectives, and maintaining a steady team pace.

Scrum differs from other Agile frameworks such as Kanban and XP by its well-structured organization of work, based on sprints, fixed roles, and clearly defined events. Scrum is excellent for teams working on complex and evolving projects where regular feedback and adaptation to new conditions are essential.

Kanban

Kanban is a visual work management system that originated in Lean manufacturing and has been adapted for software development. Although Kanban is not a classic Agile framework, it is widely used in Agile teams due to its flexibility and ease of implementation.

The basic idea of Kanban is to visualize the workflow using a Kanban board and limit the amount of work-in-progress (WIP). The Kanban board is divided into columns, each representing a stage in the work process, such as “To Do,” “In Progress,” and “Done.” Tasks move across the board from start to finish, allowing teams to see the current status of the work and identify bottlenecks.

Kanban supports the following key principles:

• Work Visualization: With a Kanban board, the entire workflow becomes visible to the team and stakeholders, helping to improve understanding of project status and task management.
• WIP Limitation: Kanban limits the number of tasks in progress at any one time, which helps to avoid overloading the team and improves the quality of task completion.
• Flow Management: Continuous improvement and optimization of the workflow based on task flow analysis and feedback.

Kanban is well-suited for projects with a continuous flow of tasks, such as support, maintenance, and operational processes. It is effective where it is important to optimize current processes, improve work visibility, and increase flexibility in task management. Kanban helps teams quickly adapt to changing priorities and maintain a steady work pace without the need for planning iterations as in Scrum.

Kanban differs from Scrum in that it has no fixed roles or iterations and focuses on managing the flow of work through visualization and WIP limitation. Kanban places less emphasis on technical practices but can be integrated with other frameworks to improve task management and optimize workflows.

Extreme Programming (XP)

Extreme Programming (XP) is an Agile framework that emphasizes technical excellence and frequent software releases. XP was designed to improve software quality and enhance the team’s ability to quickly adapt to changing requirements. This framework incorporates many engineering practices aimed at improving the development process and code quality.

XP’s core practices include:

• Pair Programming: Two developers work together at the same computer, improving code quality and enhancing collective code ownership.
• Test-Driven Development (TDD): Tests for new functionality are written first, then the code that passes those tests is developed. This ensures high quality and stability of the code.
• Continuous Integration: The team continuously integrates changes into the overall codebase, running automated tests to quickly identify and fix problems.
• Small Releases: Frequent and small releases allow for rapid delivery of a working product to users and collecting feedback.

XP is best suited for software development teams where high technical discipline and code quality are critical. This framework is particularly effective in environments with frequently changing requirements where quick responses and frequent releases are needed. XP practices help build robust, flexible, and easily modifiable software, while maintaining high productivity and engagement within the team.

XP differs from Scrum and Kanban with its strong emphasis on technical practices and code quality. While Scrum and Kanban focus on process management and team organization, XP offers a set of engineering practices that can be integrated with other frameworks to improve product quality and team efficiency.
