Data-based decision in work is an example of what?

Correct answer: Improving service by checking customer feedback and sales records

The direct answer is Option A: improving a service after checking customer feedback and sales records is a data-based decision. Data means organised facts or evidence. First, the worker collects feedback and sales figures. Next, the worker studies patterns, such as which service customers like or which product sells less. Then the worker chooses an improvement based on that evidence and later checks whether results improve. Option A is correct because it uses records and feedback before acting. Option B is wrong because a decision without information is not data-based. Option C is wrong because a rumour is unverified and unreliable. Option D is wrong because erasing records removes evidence and weakens planning. Data does not guarantee a perfect result, but it reduces guesswork and risk. Memory cue: collect, analyse, decide, review.
