System implementation phase: which activities are typically included when putting an information system into production?
-
ASystem checkouts to validate configurations and integrations
-
BPilot run at a limited site to reduce go-live risk
-
CParallel runs to compare legacy and new outputs
-
DAll of the above
-
ENone of the above
Answer
Correct Answer: All of the above
Explanation
Introduction / Context:The implementation phase transitions the solution into real operations. To control risk, teams employ checkouts, pilots, and sometimes parallel runs to verify correctness and stability.
Given Data / Assumptions:
- The system is built and ready for deployment.
- Risk must be mitigated through validation activities.
- Comparisons with the legacy system may be required.
Concept / Approach:Checkouts ensure environments are configured properly. Pilot runs validate with a subset of users. Parallel runs, when practical, compare outputs from old and new systems to detect discrepancies before full cutover.
Step-by-Step Solution:
Plan implementation strategy (pilot, phased, or big bang).Execute system checkouts (interfaces, security, backups).Use pilot or parallel to verify outcomes and gather feedback.Verification / Alternative check:Run-books and acceptance criteria should be satisfied during these activities before declaring production success.
Why Other Options Are Wrong:Each single activity is real but incomplete; best practice bundles them appropriately, hence “All of the above.”
Common Pitfalls:Skipping rollback planning; inadequate data reconciliation; insufficient user training and support readiness.
Final Answer:All of the above
