A large organization is planning to integrate multiple systems into its existing IT infrastructure. What approach should the organization consider to achieve effective integration?

Question

Options

• AAdopting a 'big bang' approach for all integrations simultaneously
• BImplementing point-to-point integration for each system
• CUsing incremental delivery for the integration of multiple components
• DChoosing direct integration with no predetermined order for deployment

• A
  7% (2)
• B
  3% (1)
• C
  76% (22)
• D
  14% (4)

Explanation

Incremental delivery (C) is correct because integrating multiple systems in planned, staged phases reduces risk, allows teams to test and validate each component before moving forward, and makes it easier to identify and fix issues without disrupting the entire infrastructure.

• A is wrong - A "big bang" approach deploys everything at once, maximizing risk; if something fails, the entire integration is compromised with no easy rollback path.
• B is wrong - Point-to-point integration creates a tightly coupled "spaghetti" architecture that becomes unmanageable as the number of systems grows, since every new system requires connections to every other system.
• D is wrong - Deploying with no predetermined order ignores dependencies between systems, which can cause cascading failures and makes troubleshooting nearly impossible.

Memory tip: Think of building a house - you lay the foundation before the walls, and walls before the roof. Incremental delivery follows the same logic: sequence matters, and each phase validates the next.
