To achieve continuous improvement, it is essential to measure. But what do we measure? In this article we highlight which quantitative values are the most important to measure, compare and monitor, from a MES system, with the aim of achieving improvements and results in our production.
But first, we are going to clarify what the KPI is in production, in order to better define our strategy.
Within our system, we have different values grouped into metrics. But we have to define from our strategy, what objectives we want to achieve and thus, we will be able to define what KPIs are essential, which will be our key performance indicators.
Below, we highlight 10 examples of production KPIs. A production KPI should be:
* However, we consider that 10 KPIs is a feasible number to develop an achievable plan. So, quality is better than quantity, and we advise you to adjust KPIs that are achievable, measurable and aligned with your strategy, that you focus on them so that you can later focus on the objective and achieve it.
It is the key indicator to measure the efficiency of a machine. Since it allows us to know the productivity and efficiency of the production processes of the plant. In the same way, it allows to know those aspects that are not favouring productivity. Among these are identified stoppages, breakdowns, quality problems, etc.
Other indicators can be controlled, such as the OOE (Overall Operation Effectiveness) or the TEEP (Total Effective Equipment Performance)
TEEP = Availability x Performance x Quality x Utilization
OEE= Performance x Availability x Quality
*Availability = actual production time/uptime.
Adequate operating time that elapses between two failures. With this KPI you can understand the reliability of a piece of equipment, in addition to its failure rate. This indicator will help us to understand the reliability of a piece of equipment, in addition to knowing the failure rate, or failure rate.
MTBF = Total Time Available (TTD) – Total Time Lost (TTP)/Number of Stops.
The TTD is considered to be the time that the equipment is not operational. This can be 24 hours or the period of time that the equipment is running.
Other reliability indicators:
MTTF (average operating time of a piece of equipment before the first failure),
MUT (average operating time after repair).
MDT Mean Down Time
It is the time that elapses, on average, between a fault and its repair. It contemplates the time that a team takes to diagnose the fault and restart the team.
MTTR= Total maintenance time/Number of repairs.
This indicator allows us to know the effectiveness of interventions, evaluate work orders, ability to maintain equipment and different equipment criteria such as: technical documentation, accessibility, safety, manufacturer, types of maintenance performed.

It is unscheduled downtime. An unexpected. Which is an indicator to project a preventive maintenance strategy with the aim of reducing the number of unscheduled stops.
It is the degree of efficiency and success in the management in a company of the Preventive Maintenance plan.
Two ways to calculate this indicator:
It tells us the time needed to carry out a Corrective, Preventive or Predictive Maintenance intervention; Quality Inspections; improvements etc It offers us the visibility to know the productivity of the team.
Total man-hours in planned, pending, scheduled, and executed tasks/divided by total man-hours available.
It is a key indicator to position ourselves in the market and thus define a strategy, as well as offering visibility into the performance of the manufacturing system and being able to optimize the cost of production.
Although each company uses a methodology to establish general expenses, the formula to calculate the unit production cost will be:
Direct material costs + Direct labor costs + Manufacturing overhead) / Units produced = CPU
Knowing which raw materials are being used in the manufacturing process is valuable information, since it offers us visibility to save on costs, space and production time.
WIP = Manufacturing lead time x Production flow value
We can also focus on finding out what materials have been discarded (scrap rate) in the manufacturing process, with the aim of being more efficient and sustainable.
Know the number of correctly completed parts of the total produced.
Essential KPI in manufacturing and selling products. With it we will know the time it takes to deliver an order since it has been made.
– OTIF (On Time In Full) u OTIF
With this indicator we measure the number of orders that have been delivered with the right quality and quantity and on time to the customer. To get a ratio, it is compared to the total number of orders.
OTIF = Number of perfect orders / Total number of orders
