Final answer:
Technical feasibility is the evaluation of whether current technology can meet the needs of a proposed IT system change. A simple, well-planned evaluation is crucial for understanding and implementing changes. Engineers must also consider scientific, ethical, economic, and legal aspects in large-scale problems.
Step-by-step explanation:
The aspect of feasibility that evaluates whether the existing technology is capable of meeting the needs identified for a proposed change to the IT system is known as technical feasibility. Making the evaluation simple and actionable ensures that program managers can easily understand what is being done and why. It is crucial to have a well-planned framework for the evaluation so that any necessary changes can be made more effectively. When engineers tackle large-scale problems, they should consider various facets such as scientific, ethical, economic, and legal aspects.
