Discuss CIMA CIMAPRA19-P03-1 Exam Topic 6 Question 56

Which THREE of the following are true with regard to managing the changeover from an old to a new computer system?

APilot changeover moves the simplest part of the business to the new system first

BParallel running involves keeping the old system running normally until certain data retention criteria are met or confidence is gained, while the new system deals with the new workload Data input is usually earned out on both systems

CAll methods of changeover carry high risk and it is the preparation consideration of data compatibility and data cleansing before the changeover which has the biggest impact on the smoothness of the transition

DPhased changeover moves individual portions of the business to the new system one at a time

EDirect changeover, or big bang, is only used when the systems are significantly different such that comparing the outputs of the two systems is largely irrelevant

FPhased changeover is the safest and slowest method of changeover

Suggested Answer: D, E, F

F being the safest method? Really? That’s surprising!

Callie 11 months ago

E seems off, I thought direct changeover was risky regardless of system differences.

Krystina 11 months ago

C is spot on, preparation is key for a smooth transition!

Rosalia 12 months ago

B sounds right, running both systems helps catch issues.

Lina 12 months ago

A is definitely not true, pilot changeover usually tests the whole system.

Carlee 1 year ago

I think phased changeover is definitely safer, but I’m not sure if it’s the slowest method. I might have mixed that up with something else.

Raina 1 year ago

I feel like all changeover methods do carry risks, but I’m not clear on how data compatibility affects the transition.

Hana 1 year ago

I remember parallel running means both systems operate simultaneously for a while, but I can't recall the specifics about data retention criteria.

Pansy 1 year ago

I think pilot changeover is about testing the new system on a small scale first, but I'm not entirely sure if it involves the simplest part of the business.

Jessenia 1 year ago

The direct changeover option is interesting. I'll need to think about when that might be the best approach compared to the other methods.

Julene 1 year ago

I feel pretty confident about this one. The descriptions of the changeover methods seem clear, and I think I have a good handle on the differences between them.

Rene 1 year ago

Okay, let's see. I think the key is to focus on the three methods mentioned - pilot, parallel, and phased. The question is asking which of these are true, so I'll need to carefully review the details of each.

Samira 1 year ago

This question seems straightforward, but I want to make sure I understand the different changeover methods before selecting my answers.

Selene 1 year ago

Hmm, the part about data compatibility and cleansing before the changeover seems really important. I'll make sure to pay close attention to that.

I agree, Kenneth. E is just asking for trouble, unless the systems are completely different. Why take that kind of risk?

Kenneth 2 years ago

Haha, direct changeover, or 'big bang' as they call it? That sounds like a disaster waiting to happen!
