4 metrics for fairer employee assessments

When workers are assessed, they appreciate knowing there's a universal standard. Otherwise, they might think you're treating them unfairly — or even worse, that criticisms are personal. Satisfaction at work doesn't rely on how someone feels about the job itself, but the benchmarks upon which you value them and offer opportunity for progression.

What really matters, then, for fairer employee reviews in manufacturing? We've compiled some metrics for training and further assessment as workers get to grips with your business. By tracking them, you'll build better profiles and a solid basis for rewards or improvements.

1. On-Time Delivery (OTD)

OTD calculates how often your employees meet their production quotas. Ideally, it should be 100%, but unplanned downtime can stop you from reaching this golden figure. There's also the chance that some people are simply working less or harder to achieve it. Divide the units delivered on time by the units delivered overall. During reviews, ask the employee what they did to aim for a healthy OTD score (90%+) or how they dealt with challenges that brought OTD down.

2. Mean Time to Repair (MTTR)

This applies to maintenance teams. As Atatus defines it, MTTR "is a metric used by maintenance departments to diagnose and fix broken equipment on average. It provides a picture of the maintenance team's ability to respond to and repair unplanned outages." Modern software, such as Enterprise Asset Maintenance (EAM), is a great way to track and document MTTR over your equipment lifecycles. If the average time keeps creeping up, you might have to retrain staff on best practices for certain machines and components.

3. Production schedule attainment

Discovering how many units you've produced in a given period is one thing, but to truly understand where employees thrive or struggle in their workflows, you must determine whether the process — and their roles within it — are paying off. Production schedule attainment uses a weekly snapshot of the tasks that are due to be performed, "freezing" them to see whether they generate expected outcomes for quotas, scrap and deliveries. If all the processes are followed correctly but OTD is still low, you might want to tweak the processes themselves, asking workers for their insights. SRCN Solutions recommends starting with a control group and that, "to attain that control group, you can use a measure to track how much work was executed in the previous week that existed before the schedule was frozen."

4. Defect density

Some workers are more responsible for defects than others. This might fall down to installing the most critical components of a product or staying vigilant on quality checks before it's approved. Can you identify which people in your manufacturing line have the most potential to cause or miss a defect? Excellent — it's a useful metric for their performance. To measure defect density, just calculate the percentage of products versus those with deficiencies. When you raise the subject, make it an open conversation; the worker may have their own ideas about reducing the chance of a mistake in the future.
