IDDEC™ institutionalises digital engineering at the programme level for Indian defence initiatives—particularly large-scale and turnkey programmes—by bringing together multi-stakeholder governance, formal authorisation mechanisms, and clearly defined operating rules.

It enables secure, governed, and auditable participation of multiple engineering software OEMs, system integrators, and defence stakeholders within a unified yet non-replacement framework, ensuring collaboration without tool displacement or vendor dominance.

• Core Principles:
  Data sovereignty and national control
• Defence-grade security within air-gapped and on-premises environments
• Controlled digital thread ownership by DRDO/DPSUs
• Neutral, vendor-agnostic orchestration without tool replacement
• Institutional governance over programme execution and evolution
