I would spend sometime working alongside the team members you want to target to find out what would be their hot buttons for a bonus. Attaching a bonus to a difficult task or a part of the business that they don't typically enjoy can suddenly make that part of the business great. At management level if we do not see or feel what they feel, our opinion on what will excite them as a bonus is sometimes off target. Just an idea. Keep up the great work and good luck! Mark
