How Do You Show HR's Impact on the Business?

Why is it so hard for HR to get the business to believe it?

Because HR usually talks about activities while management talks about results. Training hours, number of interviews or event attendance are measures of effort. They do not say whether the company sells more, spends less or takes fewer risks.

The solution is not to measure more things. It is to pick a few indicators that connect to money, time and risk, and to repeat them every month with the same formula. That way the conversation stops being a matter of opinion.

There is a second problem: the data lives in different places. Payroll is in one file, hiring in another and training in a third. Nobody cross-checks them, so nobody sees the effect of one decision on the others. Before calculating anything, agree with finance and operations on where each data point comes from.

Which indicators can I use in a simple template?

These five work as a starting point in any company. Each one is calculated with data you probably already have in payroll, hiring and training.

• Cost of turnover. Number of departures in the period × average cost of replacing a person. The replacement cost adds up advertising and hiring, onboarding, the manager's time and the productivity lost while the new person learns. For the rate, use: departures ÷ average headcount × 100.
• Time to fill vacancies. The person's start date minus the vacancy approval date, in days. Calculate it by role. To turn it into pesos: vacancy days × what that role contributes or costs per day.
• Absenteeism. Days of unplanned absence ÷ possible working days × 100. Break it down by area and by cause to see where to act.
• Early retention. People still at the company at 90 days ÷ people who joined in the period × 100. If it is low, the problem is usually in hiring or onboarding.
• Training cost per person. Total training investment ÷ number of people trained. Always pair it with an outcome indicator, for example the change in the goal that the training was meant to move.

Calculate each indicator monthly and compare it with the same month of the previous year. The trend matters more than any single data point.

How do I turn those numbers into pesos?

In three steps. First, define the cost of one unit: one departure, one vacancy day, one day of absence. Second, multiply by the quantity for the period. Third, compare the result with something management already watches, such as the area's revenue or margin.

If you do not have the exact cost, use a reasonable estimate, say so clearly and refine it over time. An honest, approximate number is more convincing than an exact one with no explanation.

How do I present it to management?

One page. At the top, the business objective you want to protect, for example meeting the sales plan or reducing operating costs. Below it, three to five indicators with their trend. At the end, the decision you need: budget, a leader's support or a process change.

Say what you did and what changed. Avoid the activity narrative. Management remembers a saving, a vacancy filled faster or a departure that was prevented.

How do I read the indicators together, and what if they look bad?

Indicators tell a story when you read them together. If turnover is high and early retention is low, the problem probably lies in hiring or onboarding. If absenteeism is concentrated in one area, look at that area's workload and leadership. If vacancies take a long time to fill and keep recurring in the same roles, the cost multiplies, because you pay for the vacancy over and over.

When a number looks bad, do not hide it. Turn it into a short plan with four parts: the likely cause, the action, the person responsible and the date when you will review the result. Management forgives a bad indicator. It has a harder time forgiving the fact that nobody saw it.

What mistakes should I avoid?

• Measuring too much. Twenty indicators dilute the message. Start with five.
• Not setting a baseline. Without a starting point you cannot demonstrate improvement.
• Changing the formula every month. If the definition changes, the trend loses its value.
• Neglecting personal data. Report in aggregate and protect individual information. In Colombia, Colombia's Law 1581 of 2012 on personal data protection applies; consult a lawyer on how to apply it in your company.
