TCS

The company operates a diversified IT services and software platforms model. It delivers consulting, custom development, systems integration, migration and managed services engagements, often structured as multi-year outsourcing or transformation programmes. These projects create value by replacing or modernising legacy IT, running business-critical processes and platforms, and providing specialist capabilities (for example, assessment delivery or sovereign cloud) that customers lack internally.

In parallel, it develops and commercialises enterprise software and cloud platforms across domains such as financial services cores, exam and learning management, AI-driven IT operations, low-code application development and compliant cloud for regulated workloads. These platforms are used both as standalone products and as anchors for larger service engagements, allowing reuse of a common technology base, faster delivery and lock-in through long-term contracts and subscriptions.
