ITPEC FE Morning April 2019 Question 66

Question

When a developmental process of utilizing big data is classified into the four (4) stages below, which of the following is an example that corresponds to the fourth stage?

[Developmental stages of big data utilization]
Stage 1: Confirmation of facts in the past and present (what was it before?)
Stage 2: Interpretation of the past and present status (why have/had it be so?)
Stage 3: Prediction of the occurrence of a possible event in the future (what is it likely to be?)
Stage 4: Development into a future activity (what should be done?)

Accepted Answer

b) Based on the big data, cases of operational errors made by users and increase in the failure rate due to such cases are estimated and the user interface is improved to make it less likely to cause operational errors.

Answer

a) Based on the analysis results of the big data in which the operation histories of many users are stored, the operational errors and their causes that were not anticipated by the manufacturer at first are found.

Answer

c) By using a simulation that uses big data, an increase in the failure rate of a product is estimated when an operational error supposed occurs repeatedly.

Answer

d) By using the Internet access function of a product, the operation histories of many users of the product are stored in big data, and the rate of using functions is clarified after the product is sold.

Option	What it does	Stage
(d)	Stores operation histories and shows how often each function is used	1: what was it?
(a)	Finds unexpected operational errors and their causes	2: why was it so?
(c)	Simulates how the failure rate would rise if an error is repeated	3: what is likely?
(b)	Estimates errors and failure rates, then redesigns the UI to prevent them	4: what should be done?
