Which word could describe someone who is focused on precision and detail?

The term that best describes someone focused on precision and detail is "meticulous." This word specifically refers to a high level of attention to detail and a thoroughness in completing tasks, ensuring that every aspect is carefully considered and executed without oversight. Meticulous individuals are often very methodical in their approach, aiming for accuracy and compliance with standards.

While "scrupulous" refers to a person who is very concerned about avoiding wrongdoing and adhering to moral principles, it doesn't necessarily imply the same focus on precision and detail in tasks as "meticulous" does.

"Cautious" suggests a carefulness or reluctance to take risks, which may indirectly relate to detail orientation but does not specifically highlight focus on precision.

"Attentive" implies being alert and observant, but again, it does not convey the same connotation of precision as "meticulous" does. Therefore, the best fit for describing someone with a focus on precision and detail is "meticulous."
