Bank of America Case Study-HBR

Explain what is the key point of this paragraph? The management was surprised which highlights some of the practical tensions in "innovation management", what is the lesson? Why?

"Not surprisingly, with this about-face the behavior of the staff reverted as well. Hosts, for instance, became reluctant to send customers over to insurance agents because they got no points for such referrals. On two occasions, in fact, supervisors witnessed a host undertake entire transactions just to make his points quota rather than direct customers to associates. The about-face also led one staff member to question Brady about senior management's commitment to the I&D Market vision. What concerned Brady and Butler the most, however, was the impact of incentives on the learning and quality of in-branch experiments."
