One of the best competitive advantages that manufacturers can gain is product quality. The quality of the products being produced can, of course, influence customers and wholesalers. But maximizing the number of quality products you produce for every hour your run production might be the real, overlooked benefit that manufacturers should be targeting.
Maximizing quality while reducing scrap, rework, and waste, ends up increasing margins and revenue. And every dollar you get today (and don’t need to spend on making up for poor products), is a dollar the company can invest in growth that competitors can’t.
This article looks at the essential elements of quality control plans, how to build a culture of continuous quality improvement, and how to sidestep common barriers to success. It helps you prepare to implement improvement methods designed to elevate deliverables from good enough to best in class.
What is quality improvement in manufacturing?
Quality improvement refers to a strategic approach to evaluating organizational performance systems, procedures, and processes. The objective of implementing a quality improvement program is to identify and correct subpar operational practices.
In manufacturing, and other industrial sectors, quality improvement often focuses on the quality of the products being produced. Quality improvement in these environments is usually defined as improving the quality of the products and increasing the number of quality units produced compared to the total number of units produced.
For example, a packaging manufacturer might see that for every 100 units of output, only 85 are good enough quality to ship to their buyer. Because every shipment can consist of thousands of units, this 85% quality rate can end up cutting into the revenue generated by the order, which is why they might be targeting quality improvement.
What is the difference between quality improvement and quality assurance?
Though the phrases go hand in hand, there is a slight difference in their meaning: quality assurance measures compliance against various industry standards.
Quality assurance focuses on ensuring that your current production standards are acceptable. In addition, it aims to optimize the relationship between employee contributions and profitability.
Alternatively, quality improvement fosters organizational change in response to routine work practices that negatively impact the quality of deliverables. Let's take a closer look at why top companies prioritize quality improvement.
Quality control vs. quality assurance: Understanding the difference
In manufacturing, people often use the terms quality assurance and quality control together, but they represent two distinct functions that are critical for your operations.
Quality assurance is a proactive approach focused on preventing defects before they happen. It involves designing and implementing processes and procedures that ensure products meet quality standards. For your maintenance team, this means setting up standardized preventive maintenance schedules, creating detailed procedural checklists, and ensuring technicians have the right training. The goal is to build quality into the manufacturing process from the start.
Quality control is a reactive approach focused on identifying defects in finished products. It involves inspection, testing, and measurement to ensure that outputs meet the required specifications before they reach the customer. These activities include inspecting a batch of parts for defects, measuring product dimensions, or testing final assembly performance. When a quality control check fails, it often triggers a corrective maintenance work order to fix the issue that caused the defect.
A strong quality improvement program uses both. Quality assurance builds the foundation for reliable processes, while quality control verifies that those processes are producing the desired results.
The cost of quality in manufacturing
Understanding the cost of quality helps you justify investments in improvement initiatives by showing the financial impact of your efforts. It breaks down into three main categories:
By investing in prevention and appraisal, you significantly reduce internal and external failure costs, leading to higher profitability and customer satisfaction.
Benefits of quality improvement programs
Smart quality improvement programs can boost workflow efficiency, cut waste, and make workplaces safer. Done right, they deliver several key benefits:
- Data-driven decisions: Make objective decisions based on data rather than opinions for more trustworthy, long-term solutions
- Enhanced reputation: Process improvements focused on customers lead to satisfied customers, better reviews, and word-of-mouth referrals
- Revenue growth: Enhanced brand reputation leads to increased sales and easier customer acquisition
- Improved team morale: Focus on fixing processes rather than blaming people creates a more positive work environment
- Risk reduction: Structured, gradual improvements have higher success rates and have been shown to improve customer safety
- Management confidence: Consistent data collection provides accurate insights into ongoing initiatives
The scope of process improvement outcomes varies based on your organization's size, budget, and ability to invest in incremental improvements.
Methods and tools for quality improvement in manufacturing
There are several proven methods you can use to guide your quality improvement efforts. While each has its own focus, they all share the goal of creating more efficient and reliable operations.
- Lean manufacturing: This method focuses on eliminating waste from your processes. For maintenance teams, this means reducing wasted time waiting for parts, minimizing unnecessary travel across the plant, and streamlining work order procedures to reduce non-value-added steps.
- Six Sigma: A data-driven methodology for eliminating defects. It uses statistical analysis to identify the root cause of process variations and implements solutions to make outcomes more consistent and predictable.
- Total productive maintenance: A holistic approach that involves everyone from operators to maintenance technicians in improving equipment reliability. By empowering operators to perform basic maintenance tasks, you free up your skilled technicians to focus on more complex preventive and corrective work, directly improving uptime and quality.
These methods achieve maximum effectiveness when modern digital tools support them. A CMMS like MaintainX helps you implement these principles by standardizing procedures, tracking performance data, and enabling communication across your entire team.
Essential elements of quality improvement plans
A quality improvement plan is a document that outlines an organization's long-term commitment to implement operational improvement activities. It should clearly define what your organization wants to improve, how you will do it, and the outcome you expect.
Your quality improvement plan should also detail how your team will test changes they make over time. It should also track and measure your progress. The best ones begin by outlining small-scale initiatives that lead to more considerable improvements.
- Leadership: The plan clearly defines the leadership structure for the program. Who is responsible for initiating what changes? How will you hold them accountable?
- Collaborative team members: Since quality improvement is a company-wide endeavor, leadership should assemble a team of stakeholders. Choose individuals from each department to help organize recommended process adaptations.
- Aspirational benchmarks: Identify comparable organizations and brainstorm how your team can apply their processes within your workflows.
- Key performance indicators: Specify the type of data each department will collect. Which metrics will illustrate success? Schedule periodic reviews of KPIs to assess results and course-correct as needed.
- Quality improvement tools: As mentioned before, several methodologies are available to organizations wanting to strategize quality improvement initiatives. Popular tools include cause-and-effect diagrams, control charts, and stratification. Some tools include performance benchmarking.
- Data management software: Quality improvement programs usually involve the restructuring of routine procedures. The easiest way to ensure compliance is to invest in work order software that allows management to assign procedural checklists to team members digitally.
How to start a quality improvement program
Developing an effective quality improvement process requires a systematic approach. Whether you're a maintenance manager at a single facility or overseeing multiple sites, these steps will help you build a successful continuous quality improvement program.
1. Create a mission statement
Write a mission statement to serve as a north star for the program. You may want to use the commonly referenced SMART—Specific, Measurable, Achievable, Realistic, and Timely—framework to organize your thoughts. It's essential to develop quantitative indicators of progress.
2. Recruit a task force
Quality improvement is a collaborative effort. As such, you'll need to recruit individuals from each department that will be affected by updated processes and procedures.
You may also want to outsource experts to fill in any missing skill sets, knowledge points, and experiences. Share your mission statement with all potential task force members and explain how the quality improvement project aligns with overall organizational objectives.
3. Organize and distribute background information
Meet to identify organizational challenges and brainstorm potential solutions. Depending on the data available, you may be able to develop several clear plans of action immediately.
4. Match problems with solutions
Work to articulate additional contextual factors, like culture, inefficient systems, and miscommunications, that may be contributing to organizational challenges. Once your group has analyzed the issues from all angles, work together to develop potential solutions. At this point, you should:
- Document recommended changes to processes, procedures, and systems.
- Plan to test your assumptions within small groups before assigning sweeping changes.
- Determine who will be responsible for documenting, assigning, and monitoring new standard operating procedures (SOPs).
Though it may be tempting to fix everything at the same time, resist the urge to take on too much. World-class organizations don’t develop overnight.
5. Build a plan for collecting and analyzing KPIs
Once again, data is a crucial aspect of practical quality improvement projects. Consistent data collection helps measure input, processes, and outcomes. On the other hand, inconsistent data retrieval leads to wasted time, energy, and resources on ineffective process adaptations.
For this reason, don't leave your meeting without putting together a data management strategy. Ideally, you want to match every objective to a quantifiable measurement of progress.
For example, a maintenance manager at a multi-site food processing facility may track schedule compliance across locations, planned maintenance percentage to reduce reactive work, and mean time to repair (MTTR) to evaluate technician efficiency and asset reliability.
6. Set team members up for success
Introduce relevant stakeholders to your new quality improvement program. Studies show that most individuals strongly resist change, even when it's for their benefit.
It's not unusual for seasoned employees to work on autopilot, jumping from one task to the next with little thought involved. Depending on the complexity of your new policies, team members may have to extend significant mental energy to learn new ways of doing things.
For this reason, it's crucial that management fully explain the reasons behind the changes. When employees agree upon the benefits, they're more likely to comply.
Also, make sure your new quality improvement processes, workflows, and policies are easily accessible. Use a mobile app like MaintainX to assign digital checklists that workers can follow from the convenience of their smartphones. As a bonus, digital work order systems provide managers with real-time updates on task completion.
Common challenges and solutions in quality improvement
Implementing a quality improvement program presents several challenges. Anticipating these roadblocks helps you develop strategies to overcome them.
- Challenge: Resistance to change. Your team may have grown accustomed to established routines. New procedures can feel disruptive.
Solution: Clearly communicate the 'why' behind any changes. Show your team how new processes will make their jobs easier and connect their work to overall company success. Start with a small pilot project to demonstrate value before a full-scale rollout. - Challenge: Lack of accurate data. You cannot improve what you do not measure. Paper-based systems or spreadsheets make it difficult to collect the data needed to identify root causes.
Solution: Use a CMMS to centralize your operational data. Track metrics like MTTR, preventive maintenance compliance, and asset downtime to get clear insights into where problems originate. - Challenge: Insufficient resources. Quality initiatives can seem like an extra cost, making it hard to secure budget and time.
Solution: Use the cost of quality framework to build a business case. Show leadership how investing in preventive measures and better tools reduces more expensive failure costs like downtime and rework. - Challenge: Poor communication. When departments work in silos, they lose important information, leading to recurring issues.
Solution: Implement a platform with built-in communication tools. When your technicians can message each other, share photos of failures, and comment directly on work orders, you solve problems faster and prevent them from happening again.
