In project estimation, which law describes the final portion of a task tending to take disproportionately longer than anticipated?

• A. 90-90 Rule
• B. Hofstadter's Law
• C. Conway's Law
• D. Putt's Law

Answer: (B)

This is about underestimating the time needed for the last pieces of a project. Hofstadter's Law states that it always takes longer than you expect, even when you try to account for that tendency. That idea fits the finish‑line overrun exactly, because final tasks—like integration, debugging, and polishing—often reveal hidden work and new issues, pushing the finish date out beyond the original plan. For example, you might think you’re almost done, but the remaining tasks end up taking much longer due to dependencies and unforeseen complexities. The other laws touch related ideas but don’t pin down this finish‑phase overrun as clearly: the 90‑90 rule speaks to time distribution in a project, Conway's Law links system design to organizational structure, and Putt's Law says work expands to fill the time available without specifically naming what happens at the end.
