In the conversion phase of the systems development life cycle, which statement is not true?

Introduction / Context:
Conversion moves an organization from the legacy solution to the new system. Success depends on close user involvement, careful cutover planning, proper documentation, and readiness of people, processes, and technology. This question asks you to identify the statement that is not true among best practices.

Given Data / Assumptions:

• Conversion may be big bang, phased, or pilot-based.
• Operational risk management and training are critical.
• Sustainable documentation reduces post go live confusion.

Concept / Approach:
Each listed statement is a recognized best practice for conversion: collaboration, phased or controlled cutover, robust documentation, and attention to non-technical elements like SOPs, roles, and training materials. Therefore, none of the statements are false.

Step-by-Step Solution:
1) Compare each statement with recognized conversion guidance. 2) Confirm that collaboration, phased transition, documentation, and non-machine readiness are all correct. 3) Therefore no statement is false in this list.

Verification / Alternative check:
Change management and ITIL style transition practices reinforce all four points as standard operating principles for cutover.

Why Other Options Are Wrong:
Option A/B/C/D: Each describes a valid conversion practice.

Common Pitfalls:
Underestimating human factors. Even technically sound conversions fail without training, communication, and support structures.

Final Answer:
None of the above
