[Informatics] 2015 ITA exam - A15

[John Schwartz]

Hi,

I would look at it another way. When working with a client, the analysis stage is when I would get the details of what data was needed. The design stage would be for working out the details of how to get it; details the client does not need to know. So for me the answer should clearly be analysis.

Dear All,
Good Question

As an analyst I am more concerned about the problem identification (recording attendance)
The process is data collection at this stage and confines to only theoretical explanation of data requirements

As a designer I will more specifically determine the data fields,  the data types, the length of those fields (where necessary), relationships, Normal forms etc

There is lot more identification going on in design stage, so in my view...
Option A is Better

Question 15

At what stage of the problem-solving methodology would the specific data requirements for recording attendances be identified?

A. design

B. analysis

C. evaluation

D. development

I said B.
?The official answer, I've found out, is A.

?But the 2015 study design's description of the PSM clearly said:
"Analysis involves: Determining the solution requirements. What information does the solution have to provide? What data is needed to produce the information?"

I'd say that 'determining what data is needed' is the same as 'identifying specific data requirements', wouldn't you?
