Abnormalities (a.k.a. Process Deviations) occurs when a product, service, process or business operation fails to meet standard operating processes (SOPs) or other requirements. These requirements may be set by external organizations, regulators, or the organization itself.

SOP requirements are often set to meet certain standards in order to avoid risks, failure, and costs. They are the prescribed algorithm that the organization has deemed to be the current understanding of the most optimal way to do something. In cases where SOPs are required by law or to obtain 3rd party certification, there can be little or no room to address improvements to these processes.

However, many SOPs are prescribed by the organization itself, and the incremental improvement of these processes can result in enhancements to efficiency, product quality, OEE and the organization's financial performance.

The first step in continuous improvement is to find opportunities for improvement. These opportunities can be suggestions, but they are usually abnormalities - i.e. situations where the SOPs were not implemented exactly as prescribed due to some unforeseen, not predicted circumstance.

Abnormality detection starts with your frontline employees having an intuitive understanding of what is supposed to happen (SOP) so they can immediately recognize and report abnormalities. Abnormalities can be related to safety, maintenance, product and general operations.

When capturing abnormalities, it is important to categorize reports so that you can provide immediate feedback and better organize your reporting. You can provide some considerations for your staff to better understand what they are reporting, to potentially aid immediate corrective actions, and to help them provide better details in their report. Of course, this process doesn't work very well with paper forms, but it works amazingly well with software.

Here are the recommended categories and subcategories as well as some helpful considerations for your frontline staff to aid next steps.

Recommended Abnormality Categories

Abnormality / Checkpoint Table — Preview

Category	Subcategory	Checkpoints	Next Steps & Considerations
Machine Breakdown	Major	Line is down. Maintenance required.	Alert supervisor immediately.
Machine Breakdown	Minor	Temporary stoppage. Operator fixed the issue.	Provide details around what happened and how you corrected the machine breakdown to aid preventive maintenance.
Minor Abnormality	Dirtiness	Is the thing dusty or dirty? Are there powders, oil, rust, or paint present? Check for sources of dirtiness.	Clean the area or provide details to sanitation.
	Scratches	Is the equipment cracking, collapsed, deformed, chipping, or bending? Is there an issue with a bolt, nut, gauge, cover, belt, or chain? Check for sources of scratches.	Clean the area or provide details to sanitation.
	Play / Looseness	Is there looseness, omission, incorrect tightening, or an excessively long bolt? Is there abnormal sound, heat, vibration, offensive odor, discoloration, or pressure?	Provide a report for maintenance to review.
	Adhesion	Is the thing clogging, sticking, or peeling off? Is there deposition?	Provide a report for maintenance to review.
Lubrication	Leaking	Is there oil depletion? Is the lubrication oil dirty? What is the oil type? Where is the leak occurring? Is there a dirty oil port, clogging, damage, or deformation? Is there a collapsed pipe?	Provide a report for maintenance to review.
	Incorrect conditions	Is the oil stored appropriately? Is the oiling equipment adequate?	Provide a report for maintenance to review.
	Incorrect indicators	Are the wrong levels indicated?	Provide a report for maintenance to review.
Source of Contamination	Product	What products are affected? Is the contamination from a leak/spill, blowing off, scattering, overflow, permeation of fluid, steam, vapor, exhaust water, burrs, chips, packing materials, sparks, smoke, adhesives, paints, or other dropped parts?	Provide details to the appropriate team for review.
	Raw Material	What raw materials were affected? Is the contamination from a leak/spill, blowing off, scattering, overflow, permeation of fluid, steam, vapor, exhaust water, burrs, chips, packing materials, sparks, smoke, adhesives, paints, or other dropped parts?	Provide details to the appropriate team for review.
	Hydraulic Oil	Is the contamination from a leak/spill, blowing off, scattering, overflow, permeation of fluid, steam, vapor, exhaust water, burrs, chips, packing materials, sparks, smoke, adhesives, paints, or other dropped parts?	Provide details to the appropriate team for review.
	Liquid Gasses	Is the contamination from a leak/spill, blowing off, scattering, overflow, permeation of fluid, steam, vapor, exhaust water, burrs, chips, packing materials, sparks, smoke, adhesives, paints, or other dropped parts?	Provide details to the appropriate team for review.

Hard-to-Reach Area	Cleaning / Inspection	Is it an issue with the equipment structure, cover, layout, foothold, space, installing height, or inadequate indicators?	Provide a report for maintenance to review.
	Lubrication	Is it an issue with the equipment structure, cover, layout, foothold, space, installing height, or inadequate indicators?	Provide a report for maintenance to review.
	Operation	Is it an issue with the equipment structure, cover, layout, foothold, space, installing height, or inadequate indicators?	Provide a report for maintenance to review.
Product Quality Defect	Foreign Matters	What product was affected? How much product was affected? Was the contamination caused by a leak/spill/overflow, blowing off, scattering, permeation of fluid, steam, vapor, exhaust water, burrs, chips, packing materials, sparks, smoke, adhesives, paints, or other dropped parts?	Describe the quality defect and provide details for quality to review.
Product Quality Defect	Manufacturing Condition	What product was affected? How much product was affected? Check humidity, vibration, collision, and temperature. Was the manufacturing condition related to ventilation, flow restrictions, insufficient force, or poor mold design?	Provide details for quality to review.
Unnecessary Things	Equipment Component	Is the area messy and disorganized?	Consider a 5S audit to determine the best way to optimize the area, and provide details below.
	Product	Is there an unnecessary thing occurring when we manufacture products that can be removed or optimized?	Provide details.
	Tools & Jigs, Spare Parts, Pipes	What is unnecessary about the thing? Why is it not required?	Provide a brief overview.
Safety Concern	Incorrect Conditions	Are there issues with a thing in the facility such as floors, steps, or stairs? Is there unevenness, cracks, peeling, or wear? Is there an issue with lighting, i.e., is it too dark?	Provide details for review by the safety committee.
Safety Concern	Incorrect Indicators	Are safety devices broken or worn? Does there need to be a visual cue present to ensure adherence to SOPs?	Provide details for review by the safety committee.

Best Practices for Managing Abnormalities

Accessibility

It is important to provide your frontline employees with an easy way to report abnormalities. Abnormality reporting is ad-hoc (happens when it happens) and not required. The consequences of not reporting are minimal and not immediate. As a result, if you don't make successful outcomes easy to attain, your staff may choose not to participate.

Motivation

Abnormality reports can be worth their weight in gold for an organization that is focused on continuous improvement and operational excellence. An unnecessary component, a potential source of contamination and a minor dirtiness report can all add up to massive savings, product quality enhancements and reduced safety incidents. So why not share the wealth and reward your staff for providing abnormalities? You can do this automatically with software like Weever, that has a built-in rewards system.

Automation

Software allows you to automate next steps and reporting so that you can spend your time more effectively on creating and implementing innovative solutions. Let computers do what they do best - crunching big data and ensuring compliance - while you do what you do best - making a positive impact on your organization and getting recognized for it!

Weever Makes it Easy
