What is Agile Programming?
Agile programming is a method or technique used to develop and create new software; it uses the iterative approach, which means that when new or additional requirements are discovered and found, they are added to the process.
When a software engineer decides to come up with new software, there are certain steps that he/ she follows like getting the list of all the requirements needed to complete this software, planning out the architecture and design of the software, writing the test code, testing the software, and finally working out any bugs. These are certain basic and fundamental steps that go into developing new software of any kind.
However, as software became more complicated, this approach no longer seemed to be practical as, in a way, you are assuming that the developer already knows what he will need before the project even begins. With new software projects, developers do not know what things they will require before the project begins.
This is where agile programming came into effect; as and when new requirements are found, they are added to the process.
Why use agile programming?
Agile software development methods have been extensively used to develop software products. However, these techniques can be applied to developing non-software products, such as computers, motor vehicles, medical devices, food, clothing, and music.
Some of the wider principles of agile software development have also found application in general management (e.g., strategy, governance, risk, finance) under the terms business agility or agile business management.
Core Principles of Agile Programming
The core principles of Agile programming include:
- Customer Satisfaction with Continuous and Early Software Delivery: Agile software development prioritizes delivering functional software to customers as early and frequently as possible. This helps incorporate customer feedback during development, resulting in a product that aligns with customer needs and expectations.
- Accommodate Changing Requirements: Agile acknowledges that software development requirements are prone to change and welcomes these changes, even late in the development process, to benefit the customer’s competitive advantage.
- Frequent Delivery of Working Software: The Agile methodology provides frequent, gradual releases of functional software. It divides the project into smaller, more manageable segments, and each iteration produces a product increment that the team can ship. This approach ensures continuous advancement and enables the team to make modifications based on customer input.
- Collaborative Approach: The Agile methodology emphasizes collaboration between cross-functional teams, stakeholders, and customers. Through regular communication, everyone involved in the project stays aligned on goals and progress, leading to shared understanding and better decision-making.
- Supportive Environment for Motivated Individuals: Agile also creates a supportive environment for motivated individuals by providing them with the resources, support, and creative freedom they need to take ownership of their work. This trust and autonomy empower team members to achieve their objectives.
- Face-to-Face Communication: Agile highly values face-to-face interaction for effective communication and quick problem resolution, even though technology offers various communication tools. Agile prefers direct communication for conveying complex information. When face-to-face interaction becomes impossible, Agile emphasizes the need for clear and frequent communication through alternative means.
- Measure Progress Primarily through Working Software: Agile prioritizes functional software over comprehensive documentation as the primary measure of progress. Although documentation is important, tangible results through working software are the ultimate goal of Agile development.
- Maintain a Sustainable Pace of Work: To ensure a healthy work-life balance and prevent burnout, agile teams maintain a consistent and sustainable pace of work. This leads to higher productivity and quality of work in the long run.
- Prioritize technical excellence and good design: Agile promotes technical excellence and good design practices to keep the software maintainable, scalable, and adaptable to future changes. Continuous attention to these aspects contributes to the overall quality of the product.
- Simplicity: Agile advocates for simplicity in software development. Keeping things simple reduces complexity, making understanding and maintaining software easier.
Methodologies
Here are some of the most widely adopted Agile methodologies:
1. Scrum:
- Scrum is a prominent Agile methodology distinguished by short, time-boxed development cycles known as sprints that usually last two to four weeks.
- A Scrum team comprises a Product Owner, a Scrum Master, and a cross-functional development team.
- Scrum ceremonies include daily stand-up meetings (daily scrums), sprint planning, sprint review, and sprint retrospectives.
- At the end of each sprint, Scrum focuses on providing a potentially shippable product increment.
2. Kanban:
- Kanban is a visual workflow management system emphasizing work-in-progress (WIP) limitations and continuous flow.
- Kanban boards visualize tasks, allowing teams to observe how work progresses through different stages.
- Unlike Scrum, Kanban does not use time-boxed iterations, and work is drawn into the system when capacity allows.
- Kanban is adaptable and frequently used for support and maintenance activities and new development.
3. Extreme Programming (XP):
- Extreme Programming is well-known for its engineering practices, prioritizing code quality, automated testing, and continuous integration.
- XP incorporates practices such as Test-Driven Development (TDD), pair programming, continuous delivery, and frequent releases.
- The customer is heavily involved in the development process, and XP emphasizes providing small, frequent releases of working software.
4. Feature-Driven Development (FDD):
- FDD aims to identify, develop, and implement specified features or functions of a software system.
- It divides development into short iterations and concentrates on feature-level progress.
- Domain modeling, feature lists, and feature-by-feature design and development are all used in FDD.
5. Lean Software Development:
- This methodology applies lean principles influenced by manufacturing practices to software development.
- It focuses on reducing waste, increasing learning, and delivering value to customers as effectively as feasible.
- Lean supports continuous improvement and the pull system, which pulls work depending on actual demand.
6. Dynamic Systems Development Method (DSDM):
- DSDM is an Agile approach created primarily for projects with short deadlines and fixed budgets.
- It provides a framework for prioritizing features and assuring on-time delivery by constraining scope and allowing for flexibility in other project factors.
7. Crystal:
- Crystal methodologies are a collection of Agile approaches that vary in complexity depending on the size and criticality of the project.
- Different “colors” of Crystal methods are used in different project contexts, ranging from the simple Crystal Clear to the more complicated Crystal Red and Crystal Maroon.
8. Disciplined Agile Delivery (DAD):
- DAD combines Agile and Lean principles with a wide range of lifecycles and practices, allowing businesses to select the approach that best meets their objectives.
- It offers guidance on architecture, design, testing, programming, and other development elements.
