Introduction to QC Interview Questions and Answers

QC (Quality Control) of a Software System or a Product is defined as a set of procedures followed by an organization or any International Standards available based on a reference for quality output of a product to ensure the efficient product deliverables to meet the customer demands and satisfaction. Different parameters that will be considered for the Software Quality are functional requirements and non-functional requirements, which directly and indirectly affect the product, such as performance, usability, and supportability. The ways of handling unexpected scenarios or situations and the error rates are majorly considered during the product’s performance. The term Software Quality Assurance is different from Software Quality Control as the software quality assurance encompasses the different standards and processes for the stable maintenance of the quality of the products, for e.g. software deliverables, processes, and documentation, reducing the number of defects, etc. In contrast, software quality control is a kind of artefact compliance validation against the established requirement criteria in finding the defects.

Customer Satisfactory Index can be improved.
Strong trust and relationship can be established with the client.
Faster application development with a smaller number of defects.

Q2. What are the different steps or processes involved in the Quality Control Procedure?

Answer:
This is the basic Quality Control Interview Question asked in an interview. The different steps or processes involved in the Quality Control Procedure are Reviewing and Testing the product as per requirement. The steps involved in the Review and Testing phases mentioned below–

Reviewing Phase:

Requirement Analysis
Design Phase
Code Build and Development
Application or Code Deployment
Test Plan phase
Implementing test cases

Testing Phase:

Unit Testing
Integration Testing
System Testing
System Integration Testing
Non-Functional Testing
User Acceptance Testing

Q3. What are the different types of Quality Control Parameters available in Software QC?

Answer:
The different types of Quality Control Parameters available in Software Quality Control are Products, processes, and Resources which are explained below:

Products: The Products are the customer’s actual requirements, which are to be delivered with at most zero defect.
Processes: The Processes are the set of rules or procedures to be followed while testing the Software System or Product to ensure the best product deliverable. The set of processes will enable the testing procedure to be carried out efficiently so as it tests the complete product without missing any functional or non-functional inabilities as per the customer requirement specifications.
Resources: Resources to be deployed are to be very efficient in terms of team or tools or technologies used. The testing procedure can be followed either by automatic or manual based on a budget of the project. If manual, then efficient resources should be available within the team in order to avoid any manual errors or defects. In contrast, Automated testing also needs a technical professional to be deployed.
