You will discover how KPIs help measure performance, improve efficiency, and optimize processes. In addition, you will learn why choosing the right indicators is essential for data to become effective decisions, and how a good KPI strategy can transform your plant’s operation. This way, you will clearly understand what a KPI is and how to use it to achieve tangible improvements in your business.
What is a KPI and why is it important in a factory?
A KPI (Key Performance Indicator) is a metric used to measure the performance of a process, area, or system in relation to established objectives.
KPIs are essential in any sector, but they take on special relevance in the industrial context, as they allow evaluating the efficiency, productivity, and profitability of a production plant.
In industry, KPIs can take many forms, from production indicators—such as the number of units manufactured per hour—to quality indicators, such as defect rates or the level of material waste. These indicators provide a clear view of how objectives are being met and facilitate informed decision-making.
What are KPIs used for in Industry?
- Measure performance: KPIs allow quantifying progress toward production, quality, and profitability goals, helping determine if the plant is meeting expected standards.
- Identify areas for improvement: by analyzing KPI trends, inefficient processes or recurring problems can be identified that require adjustments to optimize factory performance.
- Optimize decision-making: the data obtained through KPIs provide a solid basis for making strategic decisions that improve operational efficiency, such as investing in new technologies or adjusting processes.
- Align the team toward common goals: KPIs also help set clear goals within work teams, focusing efforts and motivating employees to achieve the established objectives.
Characteristics of a good KPI in the manufacturing sector
A good KPI in the industrial sector must meet certain key characteristics:
- Quantifiable: it must be measurable in numerical or percentage terms.
- Specific: each KPI must be aligned with a concrete, clearly defined objective.
- Relevant: the indicator must be directly related to the plant’s performance and profitability.
- Realistic: it must be achievable, considering available resources and industrial conditions.
- Timely: a KPI must be monitored regularly to ensure performance stays aligned with long-term objectives.
What types of KPIs are most commonly used in manufacturing?
In the manufacturing industry, the most common KPIs are grouped into three main categories: production, maintenance, and quality. Knowing what a KPI is in each of these areas provides a comprehensive view of plant performance.
Production KPIs
Production KPIs measure operational efficiency and the ability to meet demand. Some examples are:
- OEE (Overall Equipment Effectiveness): combines equipment availability, performance, and quality. Here’s how to calculate it.
- Production cycle time: measures the time from the start to the completion of a product’s manufacturing.
- Changeover time: duration to switch from one product or batch to another, key to reducing downtime and improving efficiency. It can be improved with methodologies like SMED.
- Production cost per unit: indicates how much it costs to produce a finished product.
- Resource utilization: reflects the use of materials, labor, and equipment relative to their capacity.
Quality KPIs
Quality indicators focus on ensuring products meet required standards and customers receive what they expect. These are four of the most commonly used KPIs in this department:
- Defect rate: percentage of defective products compared to the total manufactured.
- Scrap rate: measures how many materials or products are discarded for not meeting quality standards.
- Rework rate: reflects the percentage of products requiring rework before meeting quality standards.
- Customer delivery time: although also related to production and logistics, it is key to the perceived quality of service.
Maintenance KPIs
The goal of maintenance indicators is to ensure machine availability and reduce downtime. MTBF and MTTR are two of the most relevant:
- MTBF (Mean Time Between Failures): measures the average time between one breakdown and the next, helping assess equipment reliability.
- MTTR (Mean Time To Repair): indicates the average time it takes to repair a machine after a failure, allowing better planning of maintenance resources.
How to implement a KPI system in the factory?
Implementing a KPI system in a factory is not just about measurement but about turning data into decisions that improve productivity. To do this, it is crucial to understand what a KPI is and how to put it into practice in an organized way.
5 steps to get the most out of KPIs in the production plant
1. Collect reliable data: the starting point is having accurate information. MES systems like Mapex allow automating data capture for production, maintenance, and quality, avoiding manual errors and ensuring a solid foundation.
2. Define a measurement system: before using KPIs, you must establish how they will be measured. This includes recording frequency (daily, weekly, monthly), who is responsible for each indicator, and the tool where the data will be stored.
3. Visualize KPIs on dashboards: real-time dashboards are essential so operators, middle management, and executives can quickly access information. Graphs, automatic alerts, and historical comparisons help interpret results at a glance.
4. Integrate KPIs into decision-making: indicators must be used in daily operations to identify bottlenecks, detect inefficient machines, plan maintenance, or prioritize investments. A KPI without action becomes just a number.
5. Review and adjust KPIs periodically: what is a critical KPI today may stop being one if production or business goals change. That’s why it’s necessary to periodically review indicators and adapt them to new strategic or market objectives.
Practical tips to make your KPI strategy work
For a KPI strategy to add value in the factory, it is essential to communicate indicators to the entire team, focus only on a few truly relevant ones, and rely on MES technology.
Tools like Mapex allow capturing shop-floor data, integrating it with the ERP, and visualizing indicators in real-time, facilitating continuous improvement and clearly showing what a KPI is: an indicator that turns into useful information for quick and effective decision-making, as seen in these three examples:
- A packaging factory may detect that a machine’s OEE drops due to unplanned stops and schedule a preventive maintenance plan to increase it.
- A food company may reduce its defect rate by identifying in real-time which shift produces more errors and applying corrective measures.
- A metal components manufacturer may improve its MTTR by better planning maintenance resources and thus reducing downtime.

FAQs on industrial KPIs and their implementation in factories
Which production KPI is most important in Spanish factories?
OEE (Overall Equipment Effectiveness) is the key indicator for measuring efficiency, availability, and quality of equipment in Spanish and European industrial plants.
How can I reduce the defect rate in my plant?
By analyzing quality KPIs in real time and applying immediate corrective actions, such as process adjustments, operator training, and raw material control.
Which maintenance KPI helps minimize machine downtime?
MTTR (Mean Time To Repair) allows efficient planning of repairs and reduces downtime, optimizing equipment availability.
How often should KPIs be reviewed in an industrial factory?
Ideally, KPIs should be monitored in real time through dashboards, with periodic monthly, quarterly, or annual reviews depending on the criticality of each indicator.
How are KPIs integrated with an MES system in industry?
