The primary goal of software evolution is to maintain and improve the quality of software over time, ensuring its continued relevance, reliability, and maintainability.

Agile development is a common approach to software evolution that emphasizes iterative development, continuous feedback, and adaptability to changing requirements.

Software migration refers to the process of modifying software to make it compatible with new technologies or platforms, ensuring its continued functionality and relevance.

Software evolution is driven by a combination of factors, including changing user requirements, advancements in technology, business process changes, and other external influences.

Software refactoring refers to the process of restructuring existing software code to improve its design, maintainability, and performance, without changing its external behavior.

Software evolution often faces challenges such as scope creep, technical debt accumulation, legacy code maintenance, and the need to adapt to changing technologies and requirements.

Software enhancement refers to the process of adding new features or functionalities to existing software, extending its capabilities and improving its overall value.

Modular design, object-oriented design, and service-oriented architecture are common techniques used to manage the complexity of evolving software systems, promoting maintainability, extensibility, and reusability.

Software pruning refers to the process of removing obsolete or unused code from software, reducing its complexity and improving its performance and maintainability.

Version control systems, integrated development environments, and bug tracking systems are common tools used to support software evolution activities, enabling efficient collaboration, code management, and issue tracking.

Software impact analysis refers to the process of evaluating the impact of proposed software changes on the overall system, identifying potential risks, dependencies, and affected components.

Incremental development, phased development, and iterative development are common strategies for managing software evolution in large and complex systems, enabling controlled and manageable changes over time.

Software modernization refers to the process of converting legacy code into a more modern and maintainable form, improving its compatibility with current technologies and standards.

Software evolution in safety-critical systems faces challenges such as ensuring compliance with regulatory standards, managing the complexity of interconnected systems, and validating and verifying software changes to maintain a high level of safety and reliability.

Software debugging refers to the process of identifying and fixing defects in software, restoring its intended behavior and functionality.
