What is Agile Development?

Agile development is a methodology of software development that is focused on the iterative process, frequent collaboration, and the ability to be adjusted easily in the process of its implementation.

This method is often chosen for complex projects, emphasizing adaptability and the capacity to handle changing requirements and multifaceted scenarios.

Using Agile Development, teams can implement functional software components in short cycles called iterations that must be visually reviewed and enhanced in subsequent iterations. 

While Agile methodology can be useful, it must be done in contingency with an organized team and clarified goals, as step-by-step iteration may cause scope problems.

Companies should consider the application of Agile when they plan on enhancing the efficiency of the software development process to customers’ requirements and shifts in the market. Agile is beneficial for tasks that undergo more than one cycle of evaluation and modification because modifying can be done repeatedly.

Implementing Agile methodologies may alter team collaboration patterns and potentially foster innovation. These changes may be related to changes in product quality and, in turn, potentially impact customer satisfaction. 

Agile development models are methodologies that entail the practising of Agile principles during development activities such as systems development with focus on iterative advancement, collegiality and patron feedback.

These models include Scrum, Kanban and Extreme Programming, each gaining prevalence due to the balance they strike between offering structure and enabling agility for adapting to change.

Using Agile methods, software development teams break down work into manageable steps, releasing functional iterations for continuous progress and user interaction.

Consider these key factors when choosing between Agile and Iterative models for your project:

• 柔軟性： Agile is best used in projects that need high level of flexibility and constant changes. Iterative is more effective for contexts where phases of development are clear and there is less chance of change
• Customer Involvement: Agile relies heavily on the interaction process and feedback from the customers. Iterative usually requires less frequent customer engagement.
• Project Structure: Iterative models have well-defined phases and are characterized by specific milestones, while Agile provides for continuous delivery of values.

Understanding the advantages and constraints of each model is essential. To make the right decision, some important factors must be taken into consideration, such as organizational culture, team spirit, and objectives of the project. Selecting the right model may influence project efficiency, product quality, and stakeholder satisfaction.

Keep in Mind: 

• Agile: Often implemented in projects characterized by dynamicity and a requirement for flexibility in conjunction with close customer collaboration.
• Iteration: Applicable to projects characterized by well-defined stages and a more structured methodology.

Agile software development is a methodology that emphasizes adaptability, continuous customer feedback, and frequent delivery of operational software. The software industry favors this approach due to its capability to manage complex projects through division into smaller, manageable iterations.  

This approach permits the collection of feedback at various points throughout the development process, enabling potential adjustments to be made so that the product aligns with user preferences and market demands. Nevertheless, Agile software development needs a culture of open interaction and a readiness to welcome change, which can be difficult for some companies.
