constituent system
What It Means
A constituent system is an independent, fully-functional system that can operate on its own but also connects with other systems to create something bigger and more powerful. Think of it like individual puzzle pieces that are valuable by themselves but create a complete picture when combined. Each system has its own team, budget, and purpose, but they work together to deliver capabilities that none could provide alone.
Why Chief AI Officers Care
CAIOs need to understand constituent systems because AI initiatives often require integrating multiple independent systems - like AI models, data platforms, and business applications - that different teams own and manage. This creates complexity in governance, data flow, and accountability since you can't control all the pieces directly. Success depends on orchestrating systems you don't fully own, which requires different strategies for risk management and performance optimization.
Real-World Example
A fraud detection system-of-systems might include an AI model for transaction scoring (owned by the data science team), a customer database (owned by customer service), a payment processing system (owned by a third-party vendor), and a case management system (owned by the fraud team). Each works independently for its own purpose, but together they enable real-time fraud prevention that none could accomplish alone.
Common Confusion
People often confuse constituent systems with simple software components or modules within a single application. The key difference is that constituent systems are independent and valuable on their own - they have separate owners, budgets, and lifecycles, unlike components that only exist to serve one larger system.

"independent system that forms part of a system of systems (SoS) (note: Constituent systems can be part of one or more SoS. Each constituent system is a useful system by itself, having its own development, management, utilization, goals, and resources, but interacts within the SoS to provide the unique capability of the SoS)."Source: ISO/IEC_TS_5723:2022(en)
