Agile Methodology is a framework for software development under which requirements and solutions evolve through the collaborative effort of self-organizing and cross-functional teams. It advocates adaptive planning, evolutionary development, early delivery, continual improvement, and encourages rapid and flexible response to change.
Principles of Agile
The Agile methodology is grounded in twelve principles outlined in the Agile Manifesto:
- Customer satisfaction through early and continuous delivery of valuable software.
- Welcome changing requirements, even late in the development process.
- Frequent delivery of working software, typically in increments of weeks rather than months.
- Close, daily cooperation between business people and developers.
- Projects built around motivated individuals, who should be trusted.
- Face-to-face conversation as the primary mode of communication.
- Working software is the primary measure of progress.
- Sustainable development, maintaining a constant pace indefinitely.
- Continuous attention to technical excellence and good design enhances agility.
- Simplicity—the art of maximizing the amount of work not done—is essential.
- Self-organizing teams generate the best architectures, requirements, and designs.
- Regular reflections on how to become more effective, and adjustments accordingly.
Types of Agile Methodologies
Agile is an umbrella term encompassing several specific methodologies:
Scrum
Scrum is a framework for developing and sustaining complex products with specific roles, events, and artifacts.
Kanban
Kanban focuses on visualizing work, limiting work in progress, and maximizing flow.
Extreme Programming (XP)
XP emphasizes technical excellence and continuous improvement, advocating for practices such as test-driven development and pair programming.
Special Considerations
- Team Composition: Agile favors small, tightly-knit teams that can communicate efficiently.
- Customer Involvement: Frequent feedback from stakeholders is essential.
- Flexibility: Requirements can change as the project evolves, allowing for flexibility and adaptability.
- Quality Assurance: Continuous integration and testing are integral components of Agile.
Examples of Agile in Practice
- Microsoft: Uses Scrum for product development cycles.
- Spotify: Employs a customized Agile framework tailored to its company culture.
- NASA: Implements Agile for certain phases of project planning and execution.
Historical Context
Agile Methodology gained prominence in the early 2000s. The Agile Manifesto was published in 2001 by a group of software developers who were frustrated with the traditional, rigid methodologies like Waterfall.
Applicability
Agile Methodology is suited for projects where rapid delivery and adaptation are crucial. It is widely used in software development but has also been adapted for sectors like marketing and manufacturing.
Comparisons
- Agile vs. Waterfall: Unlike Waterfall, which is linear and sequential, Agile is iterative and incremental.
- Agile vs. Lean: Lean focuses on eliminating waste and optimizing processes, whereas Agile emphasizes adaptability and iterative progress.
Related Terms
- Scrum: A specific Agile framework with defined roles and processes.
- Sprint: A time-boxed period in which a specific set of work must be completed.
- User Story: A simple description of a feature from the end-user’s perspective.
- Backlog: A prioritized list of tasks and requirements.
