SDLC Interview Questions and Answers

The following environments are used while following SDLC:

• Dev: A development environment is a workspace where developers may make changes without damaging anything in a live environment. The development environment is frequently referred to as a workspace for developers.
• QA/SIT: System Integration Testing/ Quality Analysis: In a QA environment, you test your update operation against data, hardware, and software that closely resembles the production environment, and you allow intended users to test the outcome.
• UAT/PRE-PROD: User Acceptance Testing: User acceptance testing (UAT) environments, also known as staging environments, let the application's primary users try out new features before they're deployed into production. Sometimes, we call it a Pre-Production environment as well.
• PROD: The "Production" environment, sometimes known as "Live" is where real customers/users interact with the software product.

It mainly offers a mini-model of the proposed system where the minimum required features are implemented and presented to the customer/client.

• Quality Assurance ensures that the software delivered has the fewest possible defects. Quality Control is the process of ensuring that a product's quality is maintained over time.
• Quality Assurance is handled by the project's testing team, whereas Quality Control is handled by a dedicated support team that is accountable for the product's quality even if it is in the maintenance phase of software engineering.
