What is Agile methodology?
Agile methodology is a project management and software development approach that emphasizes flexibility, collaboration, and customer satisfaction. It is based on the Agile Manifesto, a set of values and principles for software development that was introduced in 2001.
In an Agile development process, the project is broken down into small, manageable pieces, and progress is tracked and reported regularly. This allows for rapid delivery of working software, improved quality, and increased customer satisfaction.
The authors of the Agile Manifesto, through their collective experience in software development and assisting others in the same, declared their prioritization of the following values:
- Individuals and interactions over processes and tools
- Working software over comprehensive documentation
- Customer collaboration over contract negotiation
- Responding to change over following a plan
The Manifesto for Agile Software Development is based on 12 principles:[
- Customer satisfaction through rapid delivery of working software
- Working software as the primary measure of progress
- Continuous attention to technical excellence and good design
- Collaboration between customers, stakeholders, and team members
- Responding to change over following a plan
- Face-to-face communication as the best form of communication
- Continuous improvement and learning
- Sustainably paced work, balancing cost, schedule, and scope
- Measurement and transparency
- Technical, design, and product management self-organizing teams
- Regular reflection and adaptation
- A flexible and evolutionary approach to software development
1. Customer satisfaction through rapid delivery of working software
The primary goal of Agile methodology is to deliver value to the customer as quickly as possible, through regular delivery of working software.
This is achieved by delivering working software in regular, incremental increments, rather than waiting until the end of the project to deliver a complete solution. The idea behind this principle is that delivering working software early and often allows teams to get feedback from customers and stakeholders, and incorporate that feedback into future iterations of the software.
2. Working software as the primary measure of progress
This principle emphasizes that the most important aspect of any software development project is the delivery of working software, rather than spending time producing extensive documentation or planning.
In contrast to traditional approaches, where progress is often measured in terms of documentation, meetings, or milestones, Agile considers working software to be the ultimate measure of success.
3. Continuous attention to technical excellence and good design
This principle emphasizes the importance of continuously improving the technical skills and abilities of the development team and ensuring that the design of the software is easy to understand, maintain, and enhance.
This helps to ensure the longevity and reliability of the software and helps to prevent technical debt from accruing over time.
4. Collaboration between customers, stakeholders, and team members
This principle emphasizes the importance of teamwork, communication, and collaboration in delivering high-quality software solutions that meet the needs of customers and stakeholders.
The Agile approach encourages active participation from all team members, including customers and stakeholders, in decision-making, problem-solving, and planning.
Collaboration is also facilitated through regular meetings, such as daily stand-ups, sprint retrospectives, and demos, which provide opportunities for team members to communicate, share ideas, and provide feedback.
5. Responding to change over following a plan
This principle emphasizes the importance of being flexible and adaptable in software development. In Agile methodology, teams prioritize responding to change over following a plan.
Unlike traditional development methodologies, which focus on following a defined process, Agile values the ability to quickly adjust plans and requirements as needed.
6. Face-to-face communication as the best form of communication
This principle emphasizes the value of direct personal interaction as the best form of communication in software development.
While remote or written communication may sometimes be necessary, the emphasis remains on in-person communication whenever possible, it is believed that face-to-face communication fosters collaboration, builds trust, and enables real-time problem-solving.
7. Continuous improvement and learning
The principle of continuous improvement and learning in Agile methodology is critical to the success of Agile teams, as it helps them stay competitive and maintain a long-term edge.
Teams focus on both the development of individuals and the improvement of the team as a whole, using regular retrospectives and feedback loops.
8. Sustainably paced work, balancing cost, schedule, and scope
This principle in Agile methodology emphasizes the importance of balancing cost, schedule, and scope in order to ensure long-term sustainability.
In Agile, this principle is often embodied through the use of time-boxed iterations*, or sprints, in which work is completed in a set amount of time and then reviewed and adapted as needed.
Teams prioritize completing a minimum viable product within each sprint, and then build upon that product in subsequent sprints. This allows teams to manage the cost, schedule, and scope of a project in a sustainable way, and to avoid burnout and other risks to the long-term success of the project.
*What is Time-boxed iterations
Agile teams break their work into smaller parts and work on each part for a set amount of time, usually 2-4 weeks. During which an Agile team completes a set of tasks or deliverables. At the end of each iteration, the team holds a “planning” session to review the progress and plan for the next iteration.
This helps them stay on track, keep the project moving forward, and prevent getting overwhelmed and tired. They keep doing this throughout the project to make sure they are delivering the best possible outcome.
9. Measurement and transparency
This principle emphasizes the importance of continuous measurement and transparency in Agile software development. This means that the team should regularly measure the progress of the project and make this information available to stakeholders, customers, and team members.
In addition, by regularly measuring progress, the team can identify any roadblocks or problems early on and make adjustments to the project plan as needed to ensure successful delivery.
10. Technical, design, and product management self-organizing teams
This principle emphasizes the idea that the most effective teams are those who are self-organized and self-managed. This means that the team members have the autonomy to make decisions about how to approach their work, and they are responsible for ensuring that the project is completed successfully.
Technical, design, and product management skills are all critical components of successful software development, and by allowing the team to self-organize, they can bring their collective expertise to bear on the project and create high-quality software. This approach leads to a more engaged and motivated team, as well as faster and more effective problem-solving and decision-making.
11. Regular reflection and adaptation
This principle emphasizes the importance of regularly pausing to reflect on the progress of a project and make any necessary adjustments to ensure success. In Agile methodology, it’s not enough to simply plan and execute a project; it’s important to continuously reassess and adapt to changing circumstances and new information.
This could involve regular retrospectives or other forms of reflection, such as reviewing metrics or feedback from stakeholders. By reflecting on what’s working and what isn’t, and making necessary changes, the team can continuously improve and increase the chances of delivering a successful project.
12. A flexible and evolutionary approach to software development
This principle emphasizes the Agile methodology’s approach to software development as a flexible and continuously evolving process. Instead of following a rigid and prescriptive plan, Agile teams approach software development as a flexible and dynamic process that can change and adapt as needed.
This allows them to respond to new challenges and opportunities, incorporate feedback and make necessary changes along the way to ensure the best possible outcome. This principle of being flexible and evolutionary is a core aspect of the Agile methodology and helps teams to deliver high-quality software that meets the evolving needs of their customers.
Agile vs Waterfall
Agile methodology is often contrasted with more traditional, “waterfall” approaches to project management, which emphasize detailed planning and sequential steps. In contrast, Agile approaches are designed to be flexible and responsive to changing circumstances, allowing teams to respond to new information, changing requirements, and customer feedback.
