Quality Assurance / Quality Control (QA/QC)

What is Quality Assurance / Quality Control (QA/QC)?

Quality assurance (QA) and quality control (QC) are two separate parts of keeping a project to its specification. QA is the process framework set before work begins, such as ISO standard checklists and the IS codes specified for concrete. QC is the physical testing during execution, such as a slump test on fresh concrete or an inspection of welds, which catches defects while they can still be fixed.

Practical example

Under the QA process, no concrete may be poured without an approved checklist. When the site engineer tests the slump on site and rejects a watery batch by sending it back to the supplier, that is QC. Together the two checks keep the structure to its design strength.

In SuperWise

SuperWise holds QA and QC in checklists. A task can carry a start or finish checklist, and with enforcement on the task cannot be marked complete until the filled checklist is approved, so a concrete pour task cannot close without its approved form. Each material delivery challan also records a quality status of satisfactory, rejected or unsatisfactory but accepted.
