This blog will explore major trends from 2014 to 2024 in key manufacturing sectors, including automotive, aerospace, electronics, food and beverage, pharmaceuticals, and heavy industrial manufacturing.

What was the Trend in 2014?

In 2014, manufacturing quality management largely centered on manual inspections, standardized processes, and lean manufacturing principles, with technology just beginning to make inroads. Quality management strategies were more reactive, focusing on identifying defects post-production rather than preventing them in real-time.

Key Technologies and Advancements in 2014

Automation and Robotics

Automation was primarily used in repetitive, high-volume tasks on assembly lines. Basic robotic systems were popular in industries like automotive, where they improved production speed but were limited in quality control applications due to the lack of advanced sensors and data integration.

In 2014, the global industrial automation market, covering robotics, control systems, and instrumentation, was valued at approximately US$1.97 billion and was projected to grow at a compound annual growth rate (CAGR) of 52%​.

Robotics adoption was significant in automotive and electronics manufacturing, with around 60% of large manufacturers using robotic arms for assembly and material handling. However, fewer than 20% used robotics for quality control​.

Lean Manufacturing and Six Sigma

Lean principles and Six Sigma methodologies were widely adopted across various sectors to improve efficiency and minimize waste. This approach focused on process standardization, defect reduction, and resource optimization rather than automated quality assurance.

By 2014, approximately 70% of Fortune 500 manufacturers had implemented Six Sigma to some degree, particularly in sectors like automotive and aerospace, where precision and waste minimization were essential​. Lean and Six Sigma were mainly data-driven but depended heavily on retrospective analysis rather than real-time data.

Statistical Process Control (SPC)

SPC was a popular tool in quality management to monitor and control manufacturing processes through statistical analysis. SPC techniques enabled companies to maintain quality by detecting trends and variations that could indicate potential issues.

SPC adoption was high, especially in high-precision industries like aerospace and pharmaceuticals, with 80% of companies in these sectors reporting regular use of statistical quality control methods​. However, SPC relied on manual data collection and analysis, limiting its scalability and real-time responsiveness.

Data Collection and Basic Analytics

Manufacturers collected data primarily through manual inspections and batch processing systems, which led to slower response times in quality control. Basic analytics was common, but data silos restricted cross-departmental insights and real-time decision-making.

In 2014, only 42% of manufacturers had integrated data analytics into their quality control processes, and the majority were using basic spreadsheet software for analysis rather than dedicated analytics platforms​. As a result, data-driven insights were often delayed, limiting their impact on immediate quality improvements.

Moving to paperless manufacturing can address these issues by reducing human error and enhancing data accuracy, as outlined in here - reducing human error through paperless systems.

Enterprise Resource Planning (ERP) Systems

ERP systems were widely adopted by 2014, primarily for resource planning, inventory management, and production scheduling. Although these systems had quality management modules, most manufacturers did not leverage ERP fully for quality tracking.

The ERP market for manufacturing in 2014 was valued at $28 billion and growing at a CAGR of 7.2%. Despite ERP's widespread use, fewer than 40% of manufacturers were using ERP systems for real-time quality tracking​. Most ERP implementations focused on production efficiency, with limited integration of quality data for predictive insights.

Supply Chain Management and Traceability

In 2014, supply chain traceability in manufacturing was in its early stages, with limited digital tools for full transparency. A notable push came from Unilever, which advocated for supply chain transparency by supporting a 2014 RSPO resolution for full traceability in palm oil sourcing. 

This resolution, which passed with 96 votes for and 84 against, highlighted a growing industry focus on transparent sourcing practices. At the time, only about 20% of manufacturers used basic traceability systems, often standalone tools that weren’t fully integrated with real-time quality control, resulting in slower issue identification across the supply chain​.

What is Now Trending in the Manufacturing Industry?

By 2024, quality management in manufacturing has become more proactive, leveraging AI, real-time data analytics, and automation to predict, detect, and prevent defects. This shift has enabled faster response times, lower error rates, and a strong focus on sustainable manufacturing practices.
