Final answer:
The most likely first step in Harley-Davidson's resurgence was improving their production quality.
Step-by-step explanation:
The most likely first step in Harley-Davidson's resurgence from a marketing perspective was improving their production quality. In the 1980s, Harley-Davidson faced a lapse in production quality, which led to a decrease in their market share and an increase in Japanese imports. To address this issue, Harley-Davidson implemented changes to their manufacturing processes and focused on producing high-quality motorcycles. This allowed them to regain market share and become the dominant player in the industry again.
