Common Mistakes to Avoid
Ecommerce projects fail when delivery governance, integration dependencies, and UX inputs do not match the provider’s operating model.
Picking an enterprise delivery partner for a time-boxed storefront change without aligning scope and decision cadence
Accenture, EPAM Systems, Thoughtworks, and Capgemini often run heavier engagement structures that can slow test-and-learn cycles for quick tweaks. Aligning scope and stakeholder decisions early reduces timeline coordination overhead for these providers.
Underestimating integration coordination across payments, inventory, and fulfillment systems
Globant and EPAM Systems handle integration across payments, inventory, and fulfillment, but multi-dependency systems can still lengthen timelines if inputs arrive late. Thoughtworks also depends on tight stakeholder alignment because multi-team programs require fast decisions for checkout and order pipeline integration.
Skipping governance and release orchestration requirements for high-traffic ecommerce apps
Accenture and Capgemini emphasize release control, testing, and security practices for safer ecommerce deployments. Projects that treat release orchestration as optional risk broken checkout flows and performance regressions.
Leaving UX direction and discovery inputs unclear for design-led delivery
R/GA and Fueled require clear product discovery inputs to prevent rework in UX direction and experimentation readiness. Dogtown Media and Publicis Sapient also need tight internal stakeholder availability because deep app scope and integration projects can stall without timely reviews and testing.
