Getting to Zero in Manufacturing

For production, the goal shouldn’t be minimizing quality escapes, but eliminating them, and that requires the deep understanding of processes you only get with an MES.

A few months ago, I needed my furnace repaired. Winters in Ohio can be brutally cold, and we needed a solution fast. The repair company rushed the replacement part from a warehouse in Arizona (because the best place to keep furnace supplies is in the brutal heat of Arizona), only to have the part arrive broken.

Quality_Control_WEB_012715.jpgI was furious (and still cold), the repair company apologetic, and the manufacturer defensive. After looking at potential solutions, we ended up going with another part supplier.  This single, broken furnace part led to a lost sale, a potentially lost customer (the repair company didn’t know if they could use the supplier again), additional charges, and a lot of aggravation - all because of a part that didn’t work.

As a manufacturer, how do you let a part out the door that doesn’t work? With so much potential risk, how do you not have processes in place for ensuring problems like this don’t happen?  The repair company tested the part the minute they received it, and quickly realized it wasn’t going to work. It wasn’t broken, there was a problem with the manufacturing – a problem quality control should have caught. 

Identifying the Source of Quality Escapes

The problem in situations like this isn’t really the processes, but the lack of shop floor visibility. They don’t know what happens between the time an order comes in and the moment it ships, so unless EVERY single part is checked, there is going to be errors and problems that slip through.

The problem is not just broken products, but also parts or materials that don’t meet specs.  Rework will mitigate this loss, but finding it later after the complete production run adds to the cost of the rework. 

The real cost of quality defects is much larger than many manufacturers realize. In the end, the cost of defects is significantly higher than the cost of a comprehensive solution to eliminate the defects.

A Comprehensive Solution for Improved Quality

To effectively address quality control, and stop shipping broken parts, you need a solution with thepower to address the entire manufacturing value chain. Consider this –a Quality Management System will give you tools for disposition programs and for analyzing data, but it won’t offer the process enforcement and pip_fixed.jpgautomated feedback loops necessary to eliminate the root cause of errors. Better production planning will help the shop floor to do their work better, and a simple data collection system will give you more data to analyze.  These systems are good at what they do, but none offer a complete solution capable of addressing the factors contributing to quality control problems.

Only an MES or paperless manufacturing system offers the complete manufacturing value chain visibility and control you need to truly address quality control.

With an MES, you have complete production visibility, with accurate and automated production records. With data collection, you can see in real time where the errors are occurring, and can design automated feedback loops to ensure problems are eliminated as they happen. You have control and visibility of the supply chain, ensuring parts and supplies meet exacting standards. By automating processes, monitoring production, and integrating best practices into production, you can begin to automate steps in a comprehensive quality control program that is a foundation of smart manufacturing.

This is what your customers have come to expect from a modern manufacturer, and there is no reason you can’t deliver what they expect.
