Common Mistakes to Avoid

Common sourcing mistakes usually come from mismatching governance expectations, QA depth, and integration scope to the chosen provider.

  • Choosing a provider that is too process-heavy for the required prototyping speed

    Deloitte Digital, Accenture Song, Capgemini Engineering, and EPAM Systems run enterprise-style governance that can slow early prototyping cycles when rapid iteration is the top priority. Thoughtworks also emphasizes governance and automated quality gates, so time-critical build plans should ensure stakeholder alignment from discovery through delivery to avoid iteration delays.

  • Underestimating device coverage and QA automation needs for cross-platform releases

    Cross-platform abstractions increase the chance of regressions if QA automation and device testing are treated as optional steps. EPAM Systems and Capgemini Engineering reduce release risk through mobile QA automation and device compatibility testing, while Globant embeds QA automation inside multi-platform release pipelines.

  • Treating backend integration as a later task instead of a delivery-critical workstream

    If API integration and identity flows are deferred, cross-platform UX can break because mobile clients depend on stable back-end contracts. Thoughtworks uses an API-first approach, and Cognizant includes API and identity integration for enterprise app modernization.

  • Expecting highly native, deeply platform-specific behavior without disciplined shared component governance

    Shared code approaches can limit highly customized device experiences when platform-specific optimization needs dominate. Deloitte Digital and Accenture Song mitigate this risk by emphasizing reusable UI components and design systems with governance, while Cognizant and Capgemini Engineering focus on compatibility testing and performance tuning.
