Final answer:
The correct answer is d. Efficient but not effective, because while Darlene's roofing crew completed the work quickly, they did not achieve the intended goal of reroofing the correct house.
Step-by-step explanation:
The scenario described with Darlene's roofing crew completing the work quickly but on the wrong house offers a good opportunity to distinguish between two business concepts: efficiency and effectiveness. The right answer to the statement that the crew was '_____________' after reroofing the wrong house is d. Efficient but not effective.
Efficiency in a business context refers to the ability to accomplish a task using the least amount of resources possible. The crew was efficient because they finished the roof quickly, indicating that they likely used their time, effort, and materials well.
However, effectiveness is about achieving the desired objective. In this case, the objective was to reroof the correct house, which they failed to do, and thus they were not effective. So while the crew's performance was efficient in terms of speed and resource use, it was not effective when it came to meeting the goal.
