ITPEC FE Subject A October 2024 Question 46

Functions and system configurations that support business processes — this is the application architecture layer of enterprise architecture (EA).

EA describes an organisation in four layers:

• •Business architecture — the business processes and information flows the strategy needs
• •Data architecture — the data used in operations and its relationships and structure
• •Application architecture — the system functions and configurations that support the business processes
• •Technology architecture — the technical components used to develop and run the systems

Answer (c)

Why not others:

• •(a) — business processes and information flows are the business architecture
• •(b) — data contents and the relationships between data are the data architecture
• •(d) — technical components for development and operation are the technology architecture

Key rule: EA layers run from business down to technology: what the business does, what data it uses, which systems do it, and what those systems run on.
