Final answer:
Herschel should use 1) an iterative and incremental approach for this project. Hence, option 1) is correct.
Step-by-step explanation:
Herschel should use an iterative and incremental approach for this project. This approach involves breaking down the project into smaller, manageable parts or iterations, with each iteration building upon the previous one.
Each iteration allows for feedback and adjustments, which can help ensure the final deliverable meets customer requirements. The iterative and incremental approach is often used when the final product is well-understood, but there may be uncertainties or changes in requirements along the way.
