QA / QC System

Quality movement practices have matured over the years, and G.H. McCulloch, Inc. remains committed to continually adapting its own quality management systems and perspectives. As the emphasis widens to include developments in systems thinking and management systems, we take into account quality planning, quality control (QC), and quality assurance (QA) in everything that we do. This ensures that we provide quality improvements that extend far beyond just QA and QC, and instead develop into a complete quality management system.


We use a management system based on five main components:

  • Overall understanding of a process/client
  • Responsibility
  • Resources
  • Servicing the process/client
  • Analysis and improvement

At G.H. McCulloch, Inc., we also know the difference between quality control and quality assurance. That’s why we work to fully understand your goals and equipment. Let’s take quality control, for example. Quality control (QC) is actually considered the most basic level of quality. QC is testing and examining a product to ensure that it’s in working order. If it’s identified to have faults, you either fix it —making sure it conforms to the specifications—or eliminate it altogether.

While useful, quality control is generally only down at the “end of the line” and it doesn’t necessarily ensure a real quality product. Quality assurance, on the other hand, maintains the core value of quality control, but it goes further “up the line” by going beyond simply testing or inspecting services that are perceived to be final products.


Quality Assurance Measures:

To ensure that a project never starts off on the wrong foot, we first prioritize quality assurance. By properly planning a service, we can insure that our engineers meet the exact specifications of our clients. Using this strategy, we’re able to operate at a much higher level and save our clients time, energy, and cost.

  • Review specifications and test procedures.
  • Review changes in design or controlled material.
  • Review test reports and carry out field tests and inspections.


Quality Control Measures:

  • Cross-checking supplies required for a service.
  • Review the quality of delivered materials and see if any corrections need to be made.
  • Inspection of equipment when a job is complete.
