Start by determining your most important KPIs

Start with a clear understanding of organizational objectives from the top down and a plan to reach them. Go beyond the immediate team. Company?wide input gives a fuller view of the work.

To keep focus, pick one or two primary KPIs, supported by secondary KPIs and team KPIs.

Ask yourself:

  • What are you and your team trying to achieve?
  • Why does this objective matter?
  • How will you know you’ve achieved it?
  • How will you measure progress?

Customer?centred KPI targets

With your top KPIs in mind, determine what drives customer behaviour and how it relates to the measures you’ve set.

Customer actions drive results. For revenue growth, ask where it will come from: higher sales volume, a larger customer base, or both. Set sales KPIs that connect to specific customer actions.

Sales KPI targets from the inside out

Once you understand targets from the customer perspective, set internal targets that support them. Align inside?out and outside?in targets. If the customer?focused goal is to increase sales volume, an internal target might be to adjust pricing or streamline the purchase path.

Ask yourself: What impact will this KPI have on customers? How will internal actions move this KPI? Both answers should point to the same outcome.

Level up your decision making

Create custom dashboards for you and your team.

Nail down the details

Tie each KPI to a specific business outcome. KPIs should fit your situation and help you reach goals. Use SMART to test each one:

  1. Is your objective Specific?
  2. Can you Measure progress toward that goal?
  3. Is the goal realistically Attainable?
  4. How Relevant is the goal to your organization?
  5. What is the Time frame for achieving this goal?

You can extend SMART to SMARTER by adding evaluate and reevaluate. Regular check?ins keep KPIs useful and current.
