    OEE Software: Understand How to Track & Improve Productivity

    Table Of Contents

      One of the greatest challenges for manufacturers is knowing what is happening on the shop floor. To solve this, manufacturers use OEE software to collect critical data to provide department heads, supervisors, and operators real-time information about shop-floor activities. This enables them to make faster, more confident production decisions.

      But if the objective of implementing production monitoring software is to understand current performance, measure that performance over time, and then improve on it, one must first define performance. To accomplish this, the most common metric for manufacturers to use is Overall Equipment Effectiveness (OEE).

      While OEE will help you identify potential losses and understand where your process is falling short, it's so much more than just a performance metric; it's the cornerstone of a continuous improvement strategy.

      What is OEE?

      Overall Equipment Effectiveness, or OEE, measures the efficiency of a machine, taking into consideration the availability, performance, and quality output variables during the run of the machine.

      OEE = Availability * Performance * Quality

      For the purposes of calculating OEE, the 3 underlying metrics used are as follows:

      1. Availability

      Availability can also be referred to as Uptime. This is the amount of time the machine is in cycle producing parts compared to the amount of time the machine is scheduled to be in cycle. Any unplanned downtime will result in a lower availability percentage (Blog: Learn how to improve your machine availability). The main factors that hinder machine availability are:

      → Equipment Failures (Breakdowns)

      → Machine Set-Up and Adjustment Time

      2. Performance

      Performance refers to the speed that parts are produced while the machine is in cycle. It is calculated as the average in-cycle time to produce a part divided by the ideal in-cycle time to produce a part. The more parts produced within a period of time, the higher a machine's performance percentage. Key factors that negatively influence performance include:

      → Machine Idling and Minor Stoppages

      → Reduced Speed of Operation

      3. Quality

      The quality metric is the percentage of good parts out of total parts produced. Any parts rejected during a run will lower the quality percentage of a machine. Some of the primary reasons for quality reduction include:

      → Process Defects

      → Reduced Yield (from startup to stable production)

      With the right information and settings populated in an OEE software, the calculation will be done automatically and populated in pre-built reports and real-time OEE dashboards that can be used for visibility on the shop floor to track production process or for deeper analysis to spot trends, bottlenecks, etc.


      What Data Should I Collect?

      Regardless of whether you use manual data collection or OEE data collection software, the following key data points should be collected:

      • Total parts
      • Good parts
      • Ideal cycle time
      • Run time
      • Planned production time

      This data is used in calculations for availability, performance, and quality.

      Benefits of Tracking OEE

      Focus on Problem Areas

      Just as many companies within manufacturing industry environments overestimate their equipment performance, so too can unmeasured, legacy, and ad-hoc production processes create a situation where operators and managers assume that one problem is their most significant concern when the real reason may be hidden.

      Tracking OEE data can help drill down to the real reason behind each problem. This allows issues to be categorized and prioritized, so that process improvement is conducted on the most pressing problems first and progresses in rank order.

      Manage Six Losses

      The concept of Six Big Losses is a standard lean tool that categorizes the type of productivity loss. Generally, these six losses include:

      1. Unplanned stops – Unplanned stops include breakdowns, tool problems, or material interruption upstream in the production line.
      2. Planned stops – Planned stops are recognized stops such as maintenance or end-of-shift stops. Small stops – Small stops can add up quickly. These are short periods for activities such as cleaning or clearing a jam.
      3. Slow cycle time – Not all jobs run at the established ideal cycle time, reducing the efficiency of produced versus expected production.

      Production Rejects

      Scrap and production rejects result from many factors, including incorrect material, training, or wear and tear.

      Startup Rejects

      In many production companies, it takes longer than it should for a machine to go “on-spec,” resulting in wasted material at startup.

      By tracking OEE, all these stops can be managed to improve processes and reduce them to the least amount of time possible. In many cases, some of the significant losses can be eliminated. By tracking OEE correctly and accurately, managers can optimize production to reduce losses.

      Reduced Equipment Costs

      When OEE is properly deployed as a metric, it can reduce equipment costs. Accurate tracking of data can help identify tool wear, out-of-spec parts due to a belt or gear wear, training issues, design problems, and other variables. Managers can use this information to develop an optimized strategy for maintenance, significantly lowering the cost of spare parts and lost tooling.

      Better ROI

      Capital equipment purchases constitute a significant investment for any production company. With OEE tracking, equipment performance is optimized. This reduces the time required to pay for the investment. This increased production also has the effect of unlocking hidden capacity, also referred to as the “hidden factory.”

      With effective OEE tracking, companies may increase equipment uptime to the point that it impacts their entire CAPEX strategy, reducing the amount of equipment that must be purchased to increase production. Not only does this affect the bottom line, but it also means that CAPEX can be spent strategically on other value-added investments or returned to the company in the form of improved cash flow.

      Improved Quality

      Of course, all these benefits cumulatively add to the improvement of production quality. OEE allows companies to optimize production processes by tackling downtime and performance at all runtime phases, including startup, maintenance, shortstops, wear-and-tear, and more. This lowers the occurrence of off-quality material, reducing the cost of lost quality and increasing production.

      Better Visualization

      When OEE metrics are used to capture, categorize, and act upon problems, a clearer picture of the whole factory floor is possible. This holistic approach can be applied at the shift, operator, or machine group level to “see” what is going on that is impacting OEE. Operators can use this visualization to adjust and further improve their performance or that of the machine. Near real-time targets can be set that match the reality on the floor, and changes can be made proactively.

      What is a Good OEE score?

      • An OEE score of 100% is perfect production; this requires only manufacturing good parts, as fast as possible, with no unplanned downtime
      • An OEE score of 85% is considered world class for manufacturers. For many companies, it is a legitimate and reasonable long-term goal.
      • An OEE score of 60% is fairly typical for manufacturers, but indicates there is room for improvement.
      • An OEE score of 40% is common for manufacturing companies that are just starting to monitor and improve their manufacturing performance. In most cases, OEE can be easily improved just by monitoring your machines and learning where the inefficiencies lie within the manufacturing process.

      Manufacturers typically work quickly to identify and solve problems but fail to take the time to understand their root causes. Knowing how to calculate and optimize your OEE can provide answers to both the big picture problem and the details surrounding the problem, and good OEE software helps accomplish this.

      The first and most important step to improving OEE is the integration of a machine monitoring system into your shop floor that can automatically collect operational data from both machines and operators. This will provide the production visibility necessary to boost OEE.

      MachineMetrics' OEE solution enables manufacturers to not only determine their current OEE but to use it to identify potential problems and understand where processes are falling short. Is it performance, quality, or availability? Does the problem lie with a certain machine, job, shift, or process?

      Measuring OEE is much more than just a performance metric; it is the cornerstone of a continuous improvement strategy. Visionary leaders can utilize OEE software to proactively identify issues and promote accountability on the shop floor. Understanding and utilizing OEE can help align the goals of management with real-time plant floor operations. This alignment will encourage all employees to be more proactive, and through this collaborative process, productivity and revenue will increase.

      What is OEE Software?

      OEE software allows companies to utilize automation and analytics to measure OEE. The software is real-time, web-based, and managed in the cloud. It provides a modular, flexible software solution for discrete manufacturing companies that are on a journey to create a smart factory that fully and accurately tracks their OEE for their production process.

      MachineMetrics uses real-time production data straight from the machine control to propogate OEE reports.

      What Does OEE Software Do?

      By connecting directly to the machine through OEM-embedded capability or by allowing connection over analog or Ethernet connection using devices and sensors located on the edge, real-time OEE software measures variables that involve performance, availability, and quality. It does this through data collection that is sent directly to the analytics engine.

      This OEE data collection is then cleansed and standardized by the software. It is then put through advanced analytics platforms to deliver relevant, actionable data for managers and operators to use.

      Choosing the Right Solution

      The right OEE data collection software will improve plant performance and drive manufacturing productivity. It will also enable managers to identify the root causes of problems and improve decision-making.

      Set Goals

      The first step in choosing the right software is to identify your goal. Is it to automate OEE data collection to eliminate the time-consuming process of manually gathering data? Is it to identify the root cause for existing problems or drive manufacturing improvement for all process issues? Whatever the goal, having a clear definition will help you identify the right OEE data collection software.

      Identify Data Types

      While all OEE data collection software is broadly used to monitor data, calculate OEE, and help management make accurate decisions to optimize processes, the types of data they can capture and the software's analytical capabilities will vary. Knowing what data you want to capture and what the software can do is critical.

      Define a Mode of Analysis

      Your ability to improve OEE depends on the insights you have to work with. The ability to quickly analyze in real time goes hand in hand with automated data collection. Gathering data through embedded devices, attached devices, and sensors with high-frequency data and sending it directly to a cloud-based platform for analysis will improve the analysis of OEE data for the entire manufacturing operation.

      Customize Insights for Users

      Once data is analyzed, getting it into the hands of the right people is crucial. Intuitive, customizable automated data collection software lets you build reports and deliver insights to the right people so it can be put into immediate action.

      In addition to continuous improvement, operators on the production line can use these insights and even add contextual data to get a machine up and running faster than with manual data collection. OEE values are displayed in easy-to-read formats that empower users.

      Put the Data to Use

      OEE data can drive continuous improvement throughout the manufacturing operation. Customizable reporting with real-time insights means the data can be put to work immediately for the root cause analysis of problems, to design innovative predictive maintenance strategies, and to reduce costs.

      Automated data collection that feeds a robust OEE software with advanced analytics and real-time capabilities will help take OEE to the next level.

      Must-Have Features

      The best OEE data collection software should be comprehensive and work across all areas where OEE data is found. This means operating at the physical level with IoT-enabled sensors and devices that have the ability to send the OEE data to the cloud. It also means using strong data processing and real-time analytics to deliver OEE data to users in a form that allows them to act. OEE software must empower action through apps, workflows, and intuitive interfaces.

      Must-have features include:

      • Automated OEE data collection
      • Customizable reporting
      • Automated quality monitoring
      • Real-Time alerts and notifications
      • Benchmarking ability
      • Intuitive dashboards and interfaces for relevant KPIs
      • Quality monitoring

      ROI of OEE Data Collection

      The benefits of OEE tracking are the same when using OEE software. However, the effect is exponentially improved. Manual recording of data can be highly inaccurate, throwing off the overall accuracy of the system. And insights and analytics outside of a software platform are fraught with missed signals and user bias.

      OEE software helps manufacturing operations by delivering visualization, insight, reporting, and prescribed actions in real-time. These actions are focused on problem areas and are more accurate and detailed than humans could perform independently. This unbiased, laser-focused analysis and problem detection frees up managers and empowers operators to help create optimized preventive maintenance programs, improve production quality, implement continuous improvement, and more, all with the use of real-time data.
