A software project using the iterative and incremental model completes three iterations. After the third iteration, what is true about the product?
AThe product is fully complete and requires no further changes
BThe product has partial functionality and can be improved in future iterations
CThe product is discarded and restarted from scratch
DThe product is only tested after all iterations are done
Step-by-Step Solution
Solution:
  1. Step 1: Understand product state after multiple iterations

    Each iteration adds features; after three, the product is partially complete and can be enhanced.
  2. Step 2: Evaluate options

    The product has partial functionality and can be improved in future iterations correctly states the product has partial functionality and can be improved further.
  3. Final Answer:

    The product has partial functionality and can be improved in future iterations -> Option B
  4. Quick Check:

    Product status after iterations = Partial and improvable [OK]
Quick Trick: Product grows with each iteration, not complete immediately [OK]
Common Mistakes:
  • Assuming product is fully done after few iterations
  • Believing testing happens only at the end
