The Incremental model involves developing a system partially in small, manageable portions. After each increment, further development is determined based on the feedback and the goals achieved in the previous increment. This approach allows for early, partial implementations and continuous refinements.

In Agile development, prototyping often starts with building a "Vertical" prototype. This prototype includes a limited set of key features that provide a deep exploration of specific functionalities. It's not a final or complete product but serves to demonstrate essential aspects of the system.

A key characteristic of Black Box Testing is that it is performed without knowledge of the internal code or system's internal logic. Testers focus on the inputs, outputs, and behavior of the software without delving into its implementation details.

Configuration Status Accounting in SCM is responsible for keeping track of all changes made to the system. It provides visibility into the status of the system's components and helps in monitoring and reporting on changes.

In white box testing, the "Code" is tested to check if it performs correctly. This involves checking that all statements and conditions in the code are tested, ensuring comprehensive code coverage.

IEEE 730 defines the standard for software quality assurance plans. It provides guidelines and requirements for creating a plan that ensures software quality throughout the development process.

The main objective of software reverse engineering is to understand and modify existing software. This process involves analyzing and deconstructing software to uncover its design, functionality, and logic, which can be valuable for various purposes, such as maintenance or improvements.

System testing is conducted to ensure that the developed software meets its requirements and functions as intended. It tests the entire system as a whole to verify that all components work together correctly.

Reverse engineering allows the development team to analyze the legacy system's code, understand its architecture, and plan modernization efforts effectively. It provides insights into the existing codebase, aiding in the upgrade process.

SQA plays a critical role in risk management by identifying potential risks in the software development process and then developing mitigation plans to address these risks. This proactive approach helps minimize the impact of risks on the project.

The Microservices architecture style involves dividing the system into smaller sub-systems that operate as separate services. Each of these services performs specific functions and can communicate with each other, creating a more modular and flexible software architecture.

Documenting every change made during software maintenance is crucial to ensure traceability and maintainability. It helps in understanding why changes were made, which is vital for troubleshooting and future enhancements.
