In today’s industrial context, where performance optimization is crucial, the Fishbone Diagram stands out as a valuable tool for identifying the root causes of inefficiencies. Measuring Overall Equipment Effectiveness (OEE) is a key indicator for evaluating industrial equipment performance. However, despite its importance, many factories struggle to maintain good OEE levels, resulting in losses in terms of productivity and profitability.

The causes of low OEE are often multiple and complex. Unplanned downtime and equipment failures can significantly affect production line availability. Moreover, micro-stops and slowdowns, often overlooked, accumulate and negatively impact TRS. Production quantity and quality suffer, leading to increased non-quality and service costs. The absence of systematic analysis makes it difficult to identify the main causes of these problems.

To address these challenges, applying methods such as Lean Manufacturing, combined with shop floor digitalization, can greatly improve the situation. The Fishbone Diagram, or Ishikawa diagram, enables visual analysis of all potential causes affecting OEE. Solutions like TeepTrak Solutions for digitalizing your production provide real-time monitoring, contributing to better visibility and proactive management of performance indicators.

A striking example is that of a fast-moving consumer goods factory, where using the Fishbone diagram reduced machine downtime by 15%. By identifying bottlenecks through tools like those from TeepTrak, the company was able to address previously disregarded micro-stops, take action through targeted staff training, and optimize its OEE. This change led to a significant increase in productivity and product quality.

To improve your production OEE, start by mapping critical steps using a Fishbone diagram. Identify key stages and prioritize “quick wins” for immediate gains. Using real-time monitoring solutions, such as those offered by TeepTrak, can amplify these benefits by aligning your entire team on performance objectives. Launch your TRS/OEE project today to transform your continuous improvement ambitions into measurable and sustainable reality.
