Agile методология разработки ПО: простое объяснение и преимущества

Agile is a flexible software development approach prioritizing team communication and adaptable product delivery.

### Agile Software Development Explained

* 🌱 **Agile** is not a programming language or framework, but a simple, flexible approach to software development.
* 👩‍💻 The speaker, Ekaterina Wexler, a 10-year veteran of large corporations (including General Motors), teaches technical skills and emphasizes practical application in her courses.
* 🌊 Traditional software development (Waterfall) involved sequential phases, often leading to late-stage issues and costly rework.  This is a lengthy process that can result in a product that doesn't meet client expectations.
* 🔄 Agile contrasts this by breaking development into short iterations (2-8 weeks), allowing for frequent feedback and adjustments. Each iteration involves designing, developing, testing, and delivering a small piece of functionality.
* 👍 Agile's advantages include faster development, lower costs, and continuous client input, minimizing the risk of major project failures.
* ⚠️ A potential drawback is reduced documentation, which can pose challenges if team members leave.  The "fast and dirty" approach prioritizes speed over extensive documentation.
* 📜 The Agile Manifesto outlines 12 principles and 4 values, available for reference.  Agile prioritizes communication and a functioning product above processes and tools.
* 🎯 Agile is an umbrella term encompassing various methodologies like Scrum and Kanban, offering a flexible framework adaptable to diverse project needs.

Agile is not a programming language, framework, or complex technical tool.

Introduction of Ekaterina Wexler, her experience in large corporations (including General Motors), and her focus on practical technical training.

Mention of her SQL and other courses with a strong emphasis on practical application.

Transition to explaining Agile and its origins.

The Waterfall Model of Software Development

Description of the Waterfall model, a multi-stage process used in software development (70s).

Example of a banking system project illustrating the Waterfall model's stages: requirements gathering, design, development, testing, and deployment.

Problem with Waterfall: discrepancies discovered during testing leading to significant rework and delays.

Consequences of the Waterfall approach: project failure and the need to restart from the beginning.

Drawbacks of the Waterfall model: lengthy process, uncertainty about the final product, high cost, and slow development.

Agile as a response to the limitations of the Waterfall model; described as a flexible development process or philosophy.

Agile's iterative approach: breaking down projects into smaller iterations (e.g., 3-week sprints).

Advantages of Agile: frequent feedback from clients, faster development, lower costs, and reduced risk of project failure.

Disadvantages and Further Clarification of Agile

Main disadvantage: less comprehensive documentation, potential knowledge loss if team members leave.

Mention of the "fast and dirty" approach and its suitability for different project scales.

Reference to the Agile Manifesto and its twelve principles and four values, available on Wikipedia.

Summary: Agile is a flexible methodology prioritizing communication, frequent feedback, and adaptability.

Agile as an umbrella term encompassing various approaches like Scrum and Kanban.
