Final answer:
Requirements Tracing likely requires the least management in the iterative design process since it is about tracking rather than altering the system. In contrast, operations like Impact Analysis, System Definition, and Software Configuration Management demand more rigorous management due to their complex nature.
Step-by-step explanation:
When managing change due to the iterative nature of the requirements process, Requirements Tracing is likely to require the least amount of management. Requirements tracing is the process of ensuring that each requirement is accounted for throughout the project lifecycle, facilitating the tracking of requirements without necessarily making alterations to the system itself. In contrast, operations like Impact Analysis, System Definition, and Software Configuration Management typically demand more extensive and active engagement in the management process. These activities include assessing how changes affect the rest of the system, defining and refining the overarching system parameters, and systematically controlling versions of the software and its configurations, which are inherently more complex and require substantial management effort.
Using a spiral design process ensures that each iteration improves upon the last, but also requires attention to time and resource constraints to prevent projects from going over budget or schedule. Through prototyping, testing, and refinement, design teams repeatedly improve upon design concepts until they meet the necessary criteria and constraints, which inherently introduces the possibility of change that must be managed.
