A company is implementing a new ERP system. The project team decides to run the old system and the new system simultaneously for two months, comparing the outputs of both systems before decommissioning the old one. Which implementation strategy is this?

Answer options:

Phased implementation

Parallel implementation

Direct cutover

Pilot implementation

How to approach this question

Identify the key characteristic: 'simultaneously' and 'comparing outputs'. This is the definition of parallel testing/implementation.

Full Answer

B.Parallel implementation✓ Correct

Parallel conversion reduces risk by ensuring the new system produces the same results as the old one before the old one is turned off. It provides a fallback option.

Common mistakes

Confusing Phased (step-by-step) with Parallel (side-by-side).
