About project

BiznessApps was a do-it-yourself mobile app builder for small and medium-sized businesses. The platform enabled non-technical users to create mobile applications with minimal custom development. Users could also manage and administer their applications without specialized technical training.

Before DeviQA

  • Testing was developer-led and lacked a defined process

  • Existing test runs failed to detect many defects

  • The bug-tracking system contained an unstructured backlog

  • Defect reports lacked consistent details and supporting evidence

  • No comprehensive test documentation

  • Major and critical defects regularly reached production

  • The customer support team lacked sufficient product knowledge

  • Releases followed no defined validation or approval process

With DeviQA

  • A structured QA and release process was established

  • Legacy defects were reviewed and retested

  • The Jira workflow was redesigned

  • Outdated issues were removed from the bug-tracking system

  • Active defect tickets were reviewed and reprioritized

  • A standardized defect report template was introduced

  • Test cases covered more than 90% of the application

  • Smoke and sanity test coverage reached 100%

  • QA engineers contributed to feature acceptance criteria

  • 1,700+ defects reported

  • 300+ blocker defects detected

  • No major or critical post-release production defects were recorded during the engagement

  • Testing covered four platforms, five browsers, and 30+ physical devices

  • Customer support issues decreased by more than 50%

  • The customer support team received product training covering the platform’s functionality

  • A defined development workflow was introduced

  • A documented release and validation workflow was established

  • BiznessApps ranked first in the Customer Happiness Awards for North America

  • BiznessApps’ ratings increased in both the App Store and Google Play

Our engagement

At the start of the engagement, BiznessApps had no structured QA process, test documentation, or consistent release validation. Testing was handled by developers, while the bug tracker contained outdated and poorly structured issues.

The six-person QA team redesigned the testing and defect-management processes. The work included updating the Jira workflow, cleaning the defect backlog, defining a test strategy, and creating 5,000+ test cases. Testing identified 1,700+ defects, including 70% classified as major priority or higher and more than 300 blockers.

Test cases covered more than 90% of the application, with complete smoke and sanity coverage before releases.

Standardized defect reports provided developers with clear reproduction steps and supporting evidence.

Product training for the customer support team contributed to a reduction of more than 50% in support issues.

During the engagement, BiznessApps’ ratings increased in the App Store and Google Play.
