Quality control has become a fundamental aspect of every industry that engineers and transports physical goods in the past decade. However, the concept of quality control is essential in the manufacturing domain.

The thing is, manufacturers strive for high-quality results and minimal rejection rates consistently to offset the steep material costs and supply to even more volatile market demand — norms in the industry.

No wonder so many manufacturing businesses have been super focused on improving their quality control workflows by integrating new technologies to enjoy a competitive advantage.

A gander at common quality control management challenges

One of the most effective ways to manage quality is through constant monitoring and control. Yes, that is obvious! Equipment must constantly be recalibrated as process drifts or other changes happen on a production line to ensure product properties remain consistent.

It is challenging for manufacturing businesses that rely heavily on wired networks and complex tooling systems to maintain quality. But it is what it is.

Wired networks are not suitable for capturing crucial data and even do not facilitate data sharing beyond the factory floor. Traditional quality management is expensive as it is based on manual post-production inspection.

The entire practice is reactive, and the quality varies considerably thus, rendering it ineffective. The data is collected manually, and through traditional systems, therefore, it does not contribute to the improvement of production efficiency.

Likewise, dense structural facilities require wireless communication that can travel long distances hassle-free. Wireless solutions should be able to integrate with legacy systems and break down data silos, providing access to previously inaccessible information.

Is IoT the answer manufacturers are seeking?

IoT or the Internet of Things is not just reinventing today's businesses; it is disrupting them for the better. IoT refers to a complete network of smart devices, people, mechanics, digital machines, and other objects that work in sync to transmit data sets from one point to another.

IoT has a proven track record of predicting maintenance issues along with processes and businesses in general. It can also deploy preventative measures. Ever since its advent, IoT has helped improve customer satisfaction and boost profits and productivity and continues to do so.

With IoT gradually paving the way across the manufacturing sector, we can expect massive transformational business opportunities.
