問題文
The heaviest statement accounts for a fifth of the total running time and the next three together account for a quarter of it. Only one change can ship this week. Which reasoning is sound?
選択肢
- Always start from the group of three because several small changes carry less risk than one change to the statement at the top of the list.
- Always start from the statement with the highest average because the callers of that statement are the ones who notice the delay in the product first.
- Compare how much of the share each change would actually remove because the largest single consumer is not always the one that can be improved the most in a week.
- Always start from the largest single consumer because the ordering of the list already reflects the volume of the improvement that each change can deliver.
