Audits & Analytics – Know for Sure

Emily Sohn’s column Peanut Butter’s Checkered Food Safety History chronicles the recent history and scope of bacterial contamination and recalls focusing on four food products – peanut butter, cantaloupe, ground beef and spinach.  Each food stuff has its particular problems be it the rough rind on cantaloupe or the multiple animal sources of ground beef plus their own favorite pathogen problems with Salmonella, E. coli or Listeria.

She rightly points to the large scale extended and complicated food supply chain as a major contributor to the outbreak problems we face in today’s food market. Our experience suggests that best first line defense is the current Food Safety Management System model contained in standards and regulations such as ISO 22000, the Food Safety Modernization Act and the Global Food Safety Initiative.

These depend on a well defined system bolstered by analytics and real-time role specific reporting for timely and well informed decision making. This is summarized by a three step program:

  • Know your production and quality systems
  • Know your supply chain
  • Know for sure – verify with audits and use analytics to get maximum results from audits.

In our direct experience we have observed that integrating HACCP programs and SPC improves food safety results and in the case of ground beef purchase by the National School Lunch Program results in supply chains that delivered ground beef that never tested positive for the pathogens monitored. We also believe the additional step of extracting actionable information from audits with analytics helps maximize the food safety outcome.

Will these strategies eliminate all possibility of food safety events? No. Will they give us the best chance of a good outcome? Yes.

Treat Metrics such as OEE as Process Parameters

Food Processors create Key Performance Indicators (KPI) to better understand what is happening in their process. One of the most common, Overall Equipment Effectiveness (OEE),  combines measures of availability, throughput and quality to provide a more comprehensive understanding of equipment or production line performance. However, a single OEE value provides very limited manufacturing decision support. Companies often short change themselves by using OEE as an isolated value and not looking at the statistics and trends.

That is where process based analytics come to the rescue. By using SPC and treating OEE like any other process parameter, manufacturers can extract far more value from the monitoring process. With statistically-based trend analysis they can quickly identify the areas that fall short in quality, throughput or availability. 

By coupling OEE with SPC, process understanding becomes part of the manufacturing culture. Since this is a component of the Manufacturing Intelligence model, it sets companies on the path to state-of-the-art manufacturing process management and enables them to:

  • Apply SPC to automated OEE solutions – looking at a single KPI value adds little to process management capability, but using control charts and process capability analysis will enable the company to deliver world-class manufacturing;
  • Rapidly determine where improvement opportunities exist;
  • Focus oninformation, not data – data is the raw material; information provides the decision support that improves performance levels.

Our article, Combine OEE and SPC for Decision Support, discusses this manufacturing intelligence-based strategy and how to turn KPIs into effective real-time decision support.

Analyze the Audits for Better Compliance

Swabbing floor drainJohn Surak gave his webinar, “Applying Process-based Analytics to Audit Results for Process Management and Improvement” yesterday. The recorded presentation is now available for you   and the slide deck is available at SlideShare

An important takeaway is that using analytics on the audit findings and applying the results to your continuous improvement program is an excellent way to strengthen your FSMS. This implies better performance on subsequent audits and improved compliance with GFSI and ISO 22000 standards.

Food Safety Webinar – How to Apply Analytics to Audits for Process Improvement

On Thursday December 15 at 11 AM PST, 2 PM PST, John Surak will present the webinr, “Applying Process-based Analytics to Audit Results for Process Management and Improvement” .

Operational audits and inspections play a critical role in assuring the effectiveness of the Food Safety Management System (FSMS). But that’s merely Step One.

Step Two and beyond involve leveraging the results from these audits to maximize value and effectiveness for process management and improvement by identifying the key process indicators, assessing them for trends, and taking action before a food-safety incident occurs. 

How to Use Audits for Process Improvement

The proper linkage and operation of the FSMS components enables successful certification audits. Additionally, it bolsters the view by Senior Management and other stakeholders that the plant has a robust food-safety management system in place.  By applying process-based analytics, management can continuously monitor the FSMS performance, improve compliance and reduce risk to the company.

The webinar will examine the data available in audits and pre-requisite program inspections and how applying analytics such as SPC can extract useful process management information. This method provides actionable feedback on the manufacturing processes and establishes a solid foundation for process management and continuous improvement. You can change audits from an unpleasant necessity to a positive contributor to your performance and bottom line.

Can You Help With Audit Analytics Case Studies?

ISO 22000 requires the analysis of results of verification activities, and SQF and BRC require annual validation of the Food Safety Management System.  The analysis of the data for either of these two activities can be easily done using SPC. 

John Surak and I presented a poster on this topic at the IAFP annual meeting this summer (http://slidesha.re/uBnW1i  ) and John will present a webinar on the topic, “Applying Process-based Analytics to Audit Results for Process Management and Improvement” on December 15, 2011 ( http://www.nwasoft.com/resources/webinars/applying-process-based-analytics-audit-results-process-management-and-improvement ) .

We are looking for additional data which to develop case studies which demonstrate the power of SPC based analytics in conducting verification activities in the food industry.

How to Apply Process-based Analytics to Audit Results

On August 1, John Surak and Jeff Cawley presented “Applying Process-based Analytics to Audit Results for Process Management and Improvement” at the International Association for Food Protection Annual Meeting. The Slide deck is attached

Operational audits and inspections play a critical role in assuring the effectiveness of the Food Safety Management System (FSMS).  To realize the maximum value and effectiveness for process management and improvement, key process indicators should be identified and plotted on control charts.  The control charts can then be assessed for trends, so actions can be taken before a food safety incident occurs. 

The proper linkage and operation of the FSMS components enables successful certification audits and gives confidence to Senior Management and other stakeholders that the plant has a robust food safety management system in place.  By applying process analytics such as SPC to sanitation data management can continuously monitor the FSMS performance.

Applying Process-based Analytics to Audits

Audit Analytics

audit analytics - swab sampleThe data gathered from food safety operational audits and inspections frequently goes no further than the summary report. The process information contained in this data can and should be used in continuous improvement programs.

On August 1, Dr. John Surak, Surak Associates, and Jeffery Cawley, NWA, will present “Applying Process-based Analytics to Audit Results for Process Management and Improvement” at the 2011 Annual Meeting of the International Association for Food Protection in Milwaukie, WI. The authors will be available for discussion at poster session P1-138 from 2:00 PM to 3:30 PM and 5:00 PM to 6:00 PM.

The presentation will examine how applying process analytics such as SPC to sanitation data provides more effective monitoring of the Food Safety Management System (FSMS) performance. This method also enables effective improvement of FSMS compliance capabilities.

The presentation is the latest in a series of studies on improving food safety by applying SPC and process improvement methods which began with the 1998 article, “Integrating HACCP and SPC”  and continued with such projects as ground beef purchase for the National School Lunch program (see Feast or Famine, “Food Safety in the Supply Chain“).
