Common Mistakes to Avoid
Misalignment between modernization goals and delivery governance leads to slowdowns across regulated infrastructure programs.
Choosing a provider without enough governance alignment for regulated change
Large-firm process rigor can slow small deployments, which can be a mismatch for EY, Deloitte, and PwC when internal stakeholder availability for data and approvals is limited. Accenture and IBM Consulting can also feel heavy if scope and governance are not well-defined, so modernization roadmaps and dependency mapping should be agreed upfront.
Underestimating legacy integration constraints until late delivery
IBM Consulting notes that integration work can surface legacy constraints late in delivery, which can compress timelines for payments and core banking modernization. Capgemini also highlights that legacy migrations demand significant upstream readiness work, so integration readiness should be validated before buildout.
Skipping an explicit operational resilience and production-run plan
Programs that focus only on migration deliverables often miss operational resilience artifacts like monitoring, incident response, and disaster recovery design. Capgemini provides operational resilience engineering with monitored recovery patterns, and PwC ties operational resilience and cyber controls frameworks directly to infrastructure delivery.
Assuming API and integration patterns will work without enterprise architecture discipline
Complex fintech architectures require coordination and testing across systems, which can slow Infosys and Wipro if governance and requirements stability are weak. Deloitte and Tata Consultancy Services emphasize delivery governance from architecture through implementation readiness, so the architecture target state and approvals should be managed tightly.
