What is a realistic lead time (and how to calculate it with data from your operation)?

In logistics and supply chain, the concept of lead time is at the center of every operational decision.
But very often the value being used isn't real: it's an inherited estimate, the contract term, or simply what "should happen".

What's the problem?
Planning deliveries and activating orders with data that doesn't reflect operational reality ends up generating deviations, emergencies and wear on the team.

What is a realistic lead time?

It's the average time that actually elapses between when an order is issued and the delivery is received under normal conditions, considering the whole logistics process: validation, preparation, dispatch, transit and receipt.

It's not the ideal.
It's not what the supplier says.
It's what actually happens in your operation.

The most common mistakes

• Using the same lead time for every supplier
• Not differentiating by item type, destination or criticality
• Adjusting dates by hand so they "add up" in the system
• Activating orders late by trusting unrealistic lead times

How to calculate the real lead time?

At Activa Proveedores we use historical data from the client's own system (PO + actual delivery date) and consolidate it automatically by supplier.

📊 This lets you see the average lead time, the dispersion and the real deviations.
🔍 Identify suppliers that systematically deliver late.
🧭 Adjust the early-activation threshold based on data.
📈 Improve deliveries without expanding the structure or changing systems.

It's also possible to extend this analysis by category or criticality, if the operation requires it.

Why does it matter?

Because measuring is only the first step.
What changes the game is using that data to anticipate activations, reduce deviations and plan better.
