Why verify before launch

Short answer

Software verification is needed before launch because defects found after release are far more expensive to fix, and failures can cause financial loss, data loss, or safety hazards. It ensures the system meets its requirements, protects users, and maintains reputation and legal compliance.

Why software verification is needed before launching any system?

Software verification checks that the product is built correctly according to its specification. It is needed before launch because:

  • Defects are cheaper to fix before release. A fault found after launch may cost 30–100 times more to fix than one found during development.
  • Users must be protected. Failures can cause money loss, data loss, security breaches or, in critical systems, injury.
  • Confidence and quality. Verification shows the system meets its functional and non-functional requirements (performance, security, reliability).
  • Reputation and legal reasons. Faulty releases damage trust, and contracts or standards often demand evidence of verification.

For example, a mobile banking app is verified to make sure a transfer debits and credits the right accounts before real customers use it.
