In change management for information systems, which of the following is a common reason to modify an existing system?

Introduction / Context:
Information systems are living assets. They must evolve to remain aligned with business strategy, operational realities, and external constraints. Understanding typical drivers of change helps prioritize roadmaps and justify investment in upgrades and refactoring.

Given Data / Assumptions:

• Organizations face shifting customer needs and regulatory landscapes.
• Technology platforms, libraries, and infrastructure improve over time.
• Production incidents and usability gaps reveal problems that require fixes.

Concept / Approach:
Three broad drivers dominate: (1) new requirements (features, reporting, compliance), (2) new technology (cloud migration, database upgrades, security protocols), and (3) problems in the current system (defects, performance bottlenecks, debt). A healthy change process triages and sequences work across these categories using impact and value metrics.

Step-by-Step Solution:
Classify each listed driver and confirm it legitimately motivates change.Recognize that real portfolios contain all three drivers concurrently.Choose the option that includes all valid drivers: All of the above.

Verification / Alternative check:
Look at any quarterly roadmap: you will see feature epics (new requirements), platform uplift items (new technology), and reliability/security work (problems) coexisting—confirming the combined answer.

Why Other Options Are Wrong:
Picking a single driver ignores the multidimensional nature of system evolution. “None of the above” conflicts with common practice.

Common Pitfalls:
Over-focusing on features while neglecting platform health; or doing only refactors while ignoring user pain. Balance is key.

Final Answer:
All of the above
