A research coordinator fans out to eight search workers, each given the full topic. Final reports contain many duplicate findings yet miss whole subtopics, and costs are high. Which change is most effective?

Answer: D — Have the coordinator map the topic first, give each worker a distinct slice, and use coverage notes to target gaps

Duplication and gaps both come from decomposition at the hub; (d) partitions scope and gives the coordinator the coverage data it needs for targeted follow-up. (a) multiplies cost and duplication. (b) treats one symptom. (c) fills gaps with unsourced content.
