You’re managing activities, not outcomes. Your diversity initiatives probably focus on “inputs” such as the number of mentoring programs, event sponsorships, or résumés collected, and you count them as successes that demonstrate senior management’s commitment to change. Instead you should think about performance as strategically as you do in your core operating businesses: Be very clear about what success will look like in five years. Define metrics to track progress toward that vision. Prioritize among competing tactics, and drive increased investment toward initiatives that produce results. Use feedback to make refinements along the way.
