This examines Yamada Denki's successful implementation of Google's P-MAX advertising tool, analyzing it through the lens of "Jobs to Be Done (JTBD) theory."

This theory posits that customers "hire" products or services as "workers" to complete specific "jobs" or achieve desired progress in particular situations.

Yamada Denki, facing the challenge of doubling e-commerce sales with limited internal resources and an increased advertising budget, "hired" P-MAX as the optimal "worker." P-MAX's automated, multi-channel capabilities and ability to uncover new demand effectively solved Yamada Denki's "job" of maximizing advertising efficiency and sales, demonstrating how understanding the customer's "situation" and "unmet needs" is crucial for a product to become the "best worker" for their "job."
