Table of Contents
here we will see what is Agile Methodology
- Iterative development: The Agile methodology encourages breaking the software development process into smaller chunks, called iterations or sprints. This makes it possible to get feedback more often and make small but steady steps forward.
- Collaboration with customers: Throughout the development process, Agile puts a lot of emphasis on close collaboration with customers or other stakeholders. This makes sure that their needs and expectations are understood and built into the software.
- Continuous delivery: Agile focuses on delivering working software in short cycles, which speeds up deployment, testing, and the ability to adapt quickly to changes.
- Adaptability: Agile recognises that requirements and priorities can change, and it encourages teams to be flexible and responsive to changing needs throughout the development process.
- Self-organizing teams: Agile gives teams the power to organise themselves, so people can work together, make decisions as a group, and take responsibility for tasks. This encourages creativity and innovation.
- Continuous improvement: Agile encourages teams to look back on the development process often to find ways to make it better. This helps teams improve their speed, quality, and overall effectiveness.
- Focus on communication: Agile understands how important it is to communicate well within the development team and with stakeholders to make sure everyone understands, quickly solve problems, and keep everyone on the same page.
- Metrics that are easy to understand: Agile uses metrics like velocity and burn-down charts to track progress and show how the project is going, which helps make decisions and improves team performance.
- Test-driven development (TDD): TDD is often a part of Agile. With TDD, tests are written before the actual code is written. This method makes sure that the code is good, that bugs are found quickly, and that the software is designed better overall.
- Accepting emergent requirements: Agile recognises that requirements may change and appear as the project goes on. It encourages teams to be flexible and welcome changes in order to make the best product possible.
Agile Methodology Key Principles
In this section we will see Key Principles of Agile:
- Customer satisfaction as a result of timely and ongoing software delivery.
- Even late in the development process, you should be open to changing needs.
- Deliver working software often, and prefer shorter time frames.
- Throughout the project, business stakeholders and developers work together.
- Build projects around motivated people and give them the environment and support they need.
- Use face-to-face conversation as the main way to talk with the team.
- Software functionality and customer satisfaction can be used to gauge progress.
- Maintain a pace that can be kept up, helping team members find a good balance between work and their personal lives.
- Focus on technical excellence and good design to increase agility.
- Keep things simple and minimise the amount of work you have to do.
- Self-organizing teams that can change and make decisions to achieve project goals.
- Think often about ways to improve and fine-tune the process.

Agile Methodology Example
Here we will see example of Agile Methodology to help you better understand it.
Imagine that a software company was asked by a client to build an e-commerce platform for the web. To ensure efficient project management and client satisfaction, the development team chooses to use the Agile Methodology.
They start by making a product backlog, which is a list of the features and functions that the e-commerce platform should have in order of importance.
Items on the backlog include user registration, the product catalogue, the shopping cart, payment integration, and order management.
The team then plans their first sprint, which typically lasts two weeks. They choose a subset of features from the product backlog that they think can be implemented during the sprint. For example, in the first sprint, they might focus on user registration and the product catalogue.
The development team works closely with the client during the sprint to clarify requirements and get feedback. They hold regular meetings, like daily stand-ups, to talk about progress, deal with problems, and make sure everyone is on the same page about the sprint’s objectives.
The team visually monitors the progress of each task within the sprint using an Agile project management tool or a physical Kanban board. This creates transparency and aids in locating any problems or bottlenecks that require attention.
The team conducts a sprint review meeting with the client at the end of the sprint. They show off the finished features, get feedback, and make any necessary changes.
The remaining items in the product backlog are then improved and given new priorities based on this feedback.
The team plans the next sprint based on the feedback they received. Taking the client’s priorities and suggestions into account, they choose the next set of features to be developed. For instance, they might work on implementing the shopping cart feature during the second sprint.
The team puts a lot of emphasis on continuous integration and testing throughout the entire development process. To ensure the web application’s stability and quality, they regularly integrate their code and run automated tests.
The team adheres to the Agile principle of frequently delivering functional software. They release a working, tested version of the e-commerce platform at the end of each sprint.
The client can then review the most recent version and give feedback, making sure that their needs are being met.
As the project goes on, the team has regular “retrospectives” to think about how they are doing things and make changes. They find ways to improve their workflow, solve any communication problems, and improve teamwork.
The team can produce a high-quality e-commerce platform that meets the client’s needs by using the Agile Methodology in this real-world web application development example.
The iterative and customer-focused approach allows for continuous feedback, adaptation to changing requirements, and early delivery of valuable features, resulting in a successful and satisfied client.

Agile Methodology Life Cycle
The following stages make up the Agile Methodology life cycle:
- Requirements Gathering: The project team works with stakeholders to identify and collect requirements for the software or product.
- Backlog Creation: The requirements are put in order and given priority to make a product backlog, which is a list of features, tasks, and user stories that changes over time.
- Sprint Planning: The team chooses a subset of items from the product backlog to work on during a sprint, which is usually a time-boxed period of 1-4 weeks.
- Sprint Execution: During the sprint, the team builds, tests, and integrates the selected backlog items while adhering to Agile principles like daily stand-up meetings and constant collaboration.
- Daily Stand-ups: The team has short meetings every day to talk about progress, deal with problems, and make sure everyone is on the same page.
- Sprint Review: At the conclusion of each sprint, the team shows the finished work to stakeholders, gets their feedback, and assesses how well the sprint went.
- Sprint Retrospective: The team evaluates the sprint, identifying what went well and where improvements can be made. They change their procedures and methods to match.
- Backlog Refinement: The product backlog is reviewed and refined on a regular basis. New requirements are added, existing items are reordered, and items that don’t need to be there are taken out.
- Continuous Integration and Testing: The team frequently integrates code changes to ensure compatibility and reduce integration problems. Additionally, they test the software as it is being developed to ensure its quality.
- Continuous Delivery: The team aims to deliver working software increments at the end of each sprint, ensuring that the product is in a deployable state.
- Adaptation and Iteration: The process is repeated for subsequent sprints, with each iteration incorporating feedback, adjusting priorities, and building on the progress made in previous sprints.
Agile Methodology Types
The types of Agile Methodology are listed below:
- Scrum: Scrum is one of the Agile frameworks that is most widely used. It uses time-boxed iterations called sprints, daily stand-up meetings, and a set of clearly defined roles like Scrum Master and Product Owner.
- Kanban: Kanban focuses on visualising the workflow and limiting work in progress (WIP). Work is pulled into the development process based on capacity and priority using a Kanban board to keep track of tasks.
- Extreme Programming (XP): XP emphasises continuous feedback, teamwork, and simplicity. It includes techniques like test-driven development (TDD), pair programming, frequent releases, and customer involvement.
- Lean Software Development: Lean Software Development focuses on getting rid of waste, improving flow, and constantly increasing efficiency. By cutting out pointless work and concentrating on what adds value, it aims to give customers value as quickly as possible.
- Crystal: The Crystal method emphasises adaptability and personalising the process to the needs of the project and the team. It focuses on communication, frequent delivery, and reflective improvement.
- Dynamic Systems Development Method (DSDM): DSDM provides a framework for quick development and delivery while making sure business needs are met. It emphasises collaboration, iterative development, and active user participation.
- Feature-Driven Development (FDD): FDD is an iterative and incremental Agile methodology that focuses on creating and delivering features. It entails domain modelling, iterative design, and feature-focused development.
