What is Average Outgoing Quality (AOQ)?

In quality administration and procedure improvement, Average leaving Quality (AOQ) reflects processing viability.

AOQ quantifies normal disconfirming units shipping to clients post-testing. It addresses imperfect things probably outmaneuvering quality checks.

AOQ (Average Outgoing Quality) involves basic acknowledgment testing, testing arbitrary tests from productions to guarantee quality cost-effectively.

Its significance lies in limiting effects on clients. High AOQ (Average Outgoing Quality) recommends numerous inconsistencies in achieving clients, undermining notoriety. Bring down AOQ shows successful inconsistencies in location and expulsion.

By understanding and surveying AOQ, associations settle on educated choices around quality control, actualize remedies, and enable non-stop upgrades serving clients and guidelines reliably.

Calculating AOQ (Average Outgoing Quality)

Average Outgoing Quality (AOQ) is a metric used in quality control and acceptance sampling to quantify the average defect rate that will be released to the customer after inspection. Calculating AOQ requires applying statistical formulas and techniques.

The basic formula for AOQ is:

AOQ = (1 – Inspection Efficiency) x Incoming Quality Level

The incoming Quality Level represents the fraction of defective in the lot or process before the inspection. Inspection Efficiency is the probability that inspection will catch a non-conforming unit.

To calculate AOQ, you first need to determine the Incoming Quality Level through methods like process control data or sampling. Inspection Efficiency depends on factors like the sampling plan parameters, measurement system capability, and inspector skill.

There are different approaches to calculating Inspection Efficiency, such as using the operating characteristic (OC) curve for the sampling plan, MILSTD-105E tables, or statistical software. The OC curve plots the probability of acceptance versus the fraction defective.

In some cases, AOQ (Average Outgoing Quality) may be calculated as AOQ = (Acceptance Number/Sample Size) x Incoming Quality Level. This approximation is valid for small incoming quality levels.

Calculating an accurate AOQ requires robust statistical techniques, representative data, and an understanding of the assumptions behind the formulas and sampling methods used.

Quality professionals must interpret AOQ results properly within the context of the quality system.

Interpreting AOQ Results

The AOQ value provides insight into the process performance and level of quality being achieved. A lower AOQ is better, indicating that a smaller proportion of nonconforming units are being released to customers on average.

AOQ = 0 represents a perfect process where no defective units are being produced. This is the ideal but often unrealistic scenario in practice. Most manufacturing processes will have some level of variation leading to occasional defects.

An AOQ of around 1-3% may be considered acceptable for many industries and processes. However, the acceptable AOQ level can vary significantly based on the product, industry standards, customer requirements, and the criticality of the application.

For example, the aerospace and medical device industries generally have much tighter AOQ requirements below 1% or even 0.1% due to the potential safety implications of defects. On the other hand, higher AOQ levels may be tolerated for lower-risk consumer products.

In addition to the numerical AOQ value, analyzing the AOQ (Average Outgoing Quality) curve can provide further insights. The shape of the curve shows how AOQ changes with different sampling plan acceptance criteria. This helps determine appropriate sampling rates to achieve the desired quality levels cost-effectively.

If the AOQ is higher than desired based on goals, specifications or industry benchmarks, it signals that improvements are needed in the manufacturing process, quality control activities, or the sampling plan parameters.

Root cause analysis and corrective/preventive actions should be employed to reduce defects and improve quality performance.

Improving AOQ (Average Outgoing Quality)

Achieving a low average outgoing quality rate is an important goal for any organization focused on quality and customer satisfaction. Several strategies can be employed to reduce the AOQ (Average Outgoing Quality) and improve overall process performance:

Tighter Process Controls

Implementing tighter statistical process controls is one of the most effective ways to drive down the AOQ. This involves rigorously monitoring process parameters and outputs using control charts and capability analysis.

Any signals of process drift or instability can then be promptly addressed through corrective and preventive actions before many nonconforming units are produced.

Error Proofing 

Mistake-proofing or error-proofing techniques like poka-yokes can prevent defects from occurring in the first place by making processes more robust to human errors. Simple tools and devices can be implemented that prevent defective items from advancing in the process.

Sampling Plan Optimization using Average Outgoing Quality

The sampling plan parameters like sample size, acceptance numbers, and sampling scheme should be periodically reviewed and optimized based on the desired AOQ, inspection costs, and other quality costs. A tighter sampling plan can reduce the AOQ but may increase inspection costs.

Root Cause Analysis

When quality issues do arise, disciplined root cause analysis using methods like 5 Whys or cause & effect diagrams is crucial. Addressing the true underlying causes through robust corrective actions rather than treating surface symptoms is key to sustainable AOQ improvement.

Supplier Quality Management using Average Outgoing Quality

For companies that receive components or materials from external suppliers, ensuring incoming quality is critically important. Supplier qualification, monitoring of supplier performance metrics, source inspection, and other supplier quality assurance activities can prevent poor quality inputs from degrading the AOQ.

Continuous Improvement Culture

Ultimately, achieving a low, stable AOQ (Average Outgoing Quality) requires an organizational culture of continuous improvement and employee engagement in quality. Methods like kaizen, suggestion systems, quality circles, and quality training can foster this mindset across the workforce.

By employing these strategies in a comprehensive quality management system, companies can systematically reduce their average outgoing quality levels, improve customer satisfaction, and reduce quality costs. Low AOQ results from robust processes, prevention over inspection, and a company-wide quality focus.

Quality Management Systems and Average Outgoing Quality

AOQ (Average Outgoing Quality) is an important metric that is closely tied to quality management systems like ISO 9001, lean manufacturing, and Six Sigma. A structured quality management system can help organizations better control and reduce their AOQ over time.

ISO 9001 is a set of international standards for quality management systems. It provides a framework for processes, procedures, and responsibilities to achieve consistent quality across products and services.

Monitoring AOQ and taking corrective actions based on it is a key part of the continuous improvement cycle in ISO 9001. The standard requires regular internal audits and management reviews to analyze quality metrics like AOQ.

Lean manufacturing principles like reducing waste and variability can directly impact AOQ. Lean tools like value stream mapping, 5S workplace organization, error-proofing, and just-in-time production help identify and eliminate non-value-adding activities that contribute to defects. This leads to better first-pass yield and lower AOQ.

Six Sigma is a data-driven methodology that aims to reduce defects and variability in processes using statistical tools. DMAIC (Define, Measure, Analyze, Improve, Control) is the Six Sigma roadmap to improving processes.

Measuring AOQ (Average Outgoing Quality), analyzing root causes of defects using techniques like Pareto charts and fishbone diagrams, and implementing improvements are core to Six Sigma. Statistical process control using control charts is also utilized to monitor and control AOQ.

Ultimately, having a robust quality management system that incorporates best practices from standards like ISO 9001 as well as methodologies like Lean and Six Sigma is crucial for gaining better control over AOQ. An integrated approach focusing on continuous process improvement is key to sustainably reducing AOQ over time.
