What is Agile? The Ultimate Introduction
n recent years, there has been a growing popularity for Agile working in the business world. What is Agile? It is an approach that emphasises flexibility, speed, and collaboration. Instead of being locked into a fixed plan, Agile project management is guided by continuous evaluation and adjustment. This makes it particularly well-suited for unpredictable projects and rapidly changing environments.
Today, we will explore the principles of Agile, popular methodologies, and the many benefits it can offer your organisation. If you're interested in discovering how Agile can help boost your team's efficiency and flexibility, read on!
What is Agile?
Agile is an innovative approach to project management that prioritises flexibility, speed, and collaboration. It was developed as a response to the limitations of traditional project management methods, which often rely on predetermined plans and large steps in the process. Agile, in contrast, emphasises an iterative and incremental approach that allows for regular evaluation and adjustment throughout the project lifecycle. This makes it easier to adapt to the changing requirements of the project quickly. Agile methodologies are commonly used in software development but can also be applied to other industries.
In essence, an agile team delivers work in small, consumable steps rather than a single big launch at the end of the project. By constantly evaluating requirements, plans, and results, teams can quickly respond to changes naturally and flexibly. This approach offers numerous advantages for organisations seeking to enhance their project management practices and streamline workflows.
The 12 Agile principles
The 12 principles of Agile are outlined in the Agile Manifesto, a document created in 2001 by a group of Agile pioneers. The principles are intended as a guide for Agile project management and are as follows:
Our highest priority is customer satisfaction through early and continuous delivery of valuable software.
Welcome changing requirements, even in late development. Agile processes harness change for the customer's competitive advantage.
Deliver working software frequently, with a preference for shorter timescales.
Businesspeople and developers must work together daily throughout the project.
Build projects around motivated individuals. Give them the environment and support they need and trust them to do the job.
A face-to-face conversation is the most efficient and effective method of conveying information to and within a development team.
Working software is the primary measure of progress.
Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.
Continuous attention to technical excellence and good design enhances agility.
Simplicity--the art of maximising the amount of work not done--is essential.
The best architectures, requirements, and designs emerge from self-organising teams.
The team regularly reflects on how to become more effective, then tunes and adjusts its behaviour accordingly.
Agile methodologies
There are many Agile methodologies, but some of the most popular ones are listed below.
Scrum
Scrum is one of the most popular Agile methodologies for software development. It utilises short iterations known as "sprints" that usually last between 2-4 weeks, during which a specific set of tasks is completed.
A cross-functional team consisting of professionals from different disciplines works together to complete these tasks, guided by a Scrum Master who facilitates the process. The Scrum Master ensures that the team follows the Scrum framework and adheres to its principles.
Scrum aims to promote teamwork, collaboration, and transparency and enable teams to deliver high-quality software products that meet the customer's changing needs. This iterative approach allows for quick feedback and adjustments, ensuring the end product is of the highest quality.
Kanban
Kanban is a visual project management method that enables teams to manage their workflow effectively. This methodology involves using cards or post-it notes to visualise the different stages of a task, from "request" to "completed".
A card represents each task, and the stage of the task is indicated by its placement on a Kanban board. This method provides teams with a clear overview of the project's progress, making it easier to identify bottlenecks, visualise dependencies, and track individual and team progress.
Kanban can be used in combination with Scrum or as a standalone methodology. When used in conjunction with Scrum, Kanban helps to visualise the work that needs to be done in each sprint, making it easier for teams to prioritise and manage their workload.
Regardless of how it is used, Kanban is an effective method for improving workflow management and increasing team productivity.
Lean
The Lean approach is based on the principles of Lean Manufacturing, which aims to eliminate waste and maximise efficiency. It utilises various tools, including Value Stream Mapping and Kaizen events, to optimise processes and reduce unnecessary steps. Organisations can streamline their workflows and boost their productivity by identifying and eliminating wasteful activities.
Value Stream Mapping is a visual tool that helps to identify inefficiencies in processes by mapping out the flow of materials and information. Meanwhile, Kaizen events involve teams coming together to identify opportunities for improvement and make changes in a short period of time.
These tools and methodologies enable organisations to improve their operations and achieve better outcomes continuously.
XP (Extreme Programming)
The Extreme Programming software development method enhances software quality by applying various best practices. These practices include pair programming, test-driven development, and regular refactoring.
Pair programming involves two developers working together on a single task, providing immediate feedback and reducing errors. Test-driven development is a process where developers write tests before the code, ensuring that the code meets the necessary requirements. Regular refactoring improves the codebase by making small changes to the code without altering its functionality.
By applying these practices, developers can significantly reduce errors, improve the quality of their code, and deliver software products that meet the needs of the end users. This approach fosters a culture of continuous improvement and encourages developers always to prioritise their work quality.
Crystal
This method aims to adapt Agile to the specific requirements of an organisation or project, with different levels of formal processes and control.
DSDM (Dynamic Systems Development Method)
DSDM, or Dynamic Systems Development Method, is an Agile project delivery framework that focuses on delivering functional software within a fixed timeframe and budget. This approach places a strong emphasis on business-driven and technically enabled projects.
DSDM encourages active involvement from stakeholders throughout the project, enabling them to provide feedback and direction throughout the development process. The framework also includes a robust quality management process ensuring the software meets the requirements and standards.
DSDM employs iterative and incremental development methods, dividing the project into a series of phases that build on one another. Each phase has specific goals and objectives, and the project team continually evaluates progress and adapts plans as needed. This approach promotes flexibility and enables the team to adjust to changing requirements, ensuring that the final product meets the needs of the end users.
DSDM suits various software development projects, from small-scale applications to large, complex systems.
These are just some of the many Agile methods that exist. Many organisations choose to use a combination of methods that best fit their specific situation and requirements.
Pros and Cons of Agile Working
Agile working can offer various advantages, such as:
Flexibility: Agile methods enable teams to respond quickly to changes in project requirements or priorities and quickly adjust the plan or scope.
Speed: Agile methods enable teams to quickly deliver valuable software or products through the use of short iterations (sprints) and continuous testing and evaluation.
Better collaboration: Agile methods enable teams to work closely together and improve communication through the use of stand-up meetings, retrospectives, and pair programming.
Increased quality: Agile methods enable teams to increase the quality of software or product by applying practices such as test-driven development, code reviews, and regular refactoring.
Higher customer satisfaction: Agile methods enable teams to better address customer requirements through techniques such as user stories and involving the customer in the process.
More visibility and transparency: Agile methods enable teams to understand better the project's progress through tools such as burndown charts and regular retrospectives.

Agile is a methodology for software development that emphasises collaboration, flexibility, and rapid iteration.
Agile works by breaking down the software development process into smaller, more manageable stages called sprints. Each sprint involves planning, development, testing, and review, with a focus on delivering working software at the end of each sprint.
The benefits of Agile include increased flexibility, faster delivery times, improved collaboration and communication, and better alignment with customer needs.
Common Agile methodologies include Scrum, Kanban, and Extreme Programming (XP).
Agile differs from traditional software development methods in its focus on collaboration, flexibility, and iterative development. Traditional methods typically involve a more rigid, sequential approach.
To successfully adopt Agile, an organisation should start with a clear understanding of the principles and practices of Agile, and should involve all stakeholders in the adoption process. It is also important to provide training and support to team members, and to regularly review and adapt processes to ensure ongoing improvement.
