Exin EPI IT Management CITM Question # 9 Topic 1 Discussion

When implementing a new system, the customer’s concern about a large impact on the user base suggests the need for a low-risk, controlled adoption strategy. Inapplication management, theparalleladoption approach (B) involves running both the old and new systems simultaneously for a period, allowing users to transition gradually while ensuring the new system functions correctly. This minimizes disruption, as the old system remains operational as a fallback if issues arise with the new system.

Big bang (A):This approach involves switching entirely to the new system at once, which is high-risk and likely to cause significant disruption, especially for a concerned user base. It’s unsuitable here due to the potential for widespread impact.

Coordinated (C):This is not a standard term in application deployment strategies. It may imply a managed transition but lacks the specificity of parallel or phased approaches.

Phased (D):This involves rolling out the new system incrementally (e.g., by department or module), which reduces risk but doesn’t provide the same level of safety as parallel, where both systems run concurrently to ensure continuity.

Theparallelapproach is ideal for mitigating risks during a critical system transition, as it allows validation of the new system’s performance while maintaining business continuity. According toITILorSDLCframeworks, parallel adoption is often recommended for mission-critical systems to ensure stability and user acceptance.
