What is QA testing?

"QA" is an abbreviation for "Quality Assurance." With QA testing, the company makes sure that the product they are going to deliver to consumers meets their standards of functionality, reliability, and security.


How do you determine the bearing capacity from unconfined compressive strength of clayey soils?

The allowable bearing capacity (qa) is about one tenth of the unconfined compressive strength (UCS).ie qa = UCS / 10


Who is the first QA Manager in the Mohali?

Mr. Pramod Kumar Singh (Jujhar Nagar) Punjab


Quality assurance and quality control?

From my experience in QA, this is one of the most common misconceptions in the field - people think Quality Assurance and Quality Control are the same thing. They're absolutely not, and understanding the difference is crucial for anyone working in software development. Quality Assurance (QA) is proactive - it's about preventing defects before they happen. QA focuses on establishing processes, standards, and procedures that ensure quality is built into the product from the beginning. Think of it as creating a framework that makes it nearly impossible for bad code to reach production. Quality Control (QC) is reactive - it's about detecting and fixing defects after they occur. QC involves testing, inspecting, and validating the finished product to catch issues before they reach users. The key differences I see in practice: Timing: QA happens throughout the entire development lifecycle, while QC typically occurs at the end during testing phases. Focus: QA is process-oriented (how we build software), while QC is product-oriented (what we actually built). Approach: QA asks "Are we following the right processes?" while QC asks "Does this product work correctly?" Examples from my experience: QA activities: Writing coding standards, establishing review processes, creating test strategies, setting up CI/CD pipelines QC activities: Running test cases, performing code reviews, conducting user acceptance testing, bug reporting The relationship: QC is actually a subset of QA. You can't have effective quality control without solid quality assurance processes in place first. In practice, both are essential. Great QA processes reduce the number of defects QC needs to catch, but you still need QC as your safety net. Teams that only focus on one usually struggle with quality issues - either they're constantly firefighting bugs (weak QA) or they're shipping products with obvious defects (weak QC).


Define the term negative slip in reciprocating pump?

When the actual flow (Qa) is greater than theoretical flow (Qt) in a reciprocating pump it is negetive slip.
