Today we again ran the Haesung Group Advanced Sales Capability course at the Haesung 1 Building training center. The participants were sales managers at Hankook Package at the section-chief level and above. In the morning, we started by putting yesterday’s team worksheets back on screen, one sheet at a time. Even within the same company, teams had split their pipelines differently, into six stages on one team and nine on another. The afternoon was all about AI. Last night I sorted photos of the worksheets into a folder for each team, and with those they built a proposal replying to a mock customer email. Next they wrote a pipeline management program for their team, and finally each person went on to build a tool for something they do every day. One thought stayed with me while preparing for the session. Tidying tables, counting days of stay, drafting proposals, and writing management programs are now things an AI agent can do in a few minutes. So what is left for section-chief and deputy-general-manager-level sales professionals? I think it is knowing where and why a deal has stalled, deciding what terms to set, and holding to those terms in front of the customer. A few field sales teams who struggled a bit in yesterday’s theory session built the most tools this afternoon: alerts for accounts below target, order-progress tracking, and organizing customer credit information. Only someone who knows the work can decide what to hand to AI. Have a great weekend^^b
