ITPEC IP October 2020 Question 95
The task of using statistics, machine learning, and other such methods to analyze large volumes of data and gain hints and ideas for the creation of new services and value is now very important. Which of the following is the most appropriate human resource to perform this task?
Explanation
Data scientist — the specialist who analyses large volumes of data with statistics and machine learning to find hints for new services and value.
A data scientist combines three skills: data science (statistics, modelling, machine learning), data engineering (collecting, cleaning and processing big data with programs), and business sense (asking the right question and turning the findings into action). The role grew in importance as companies began to collect big data from web logs, sensors and transactions and to look for value in it.
Answer (d)
Why not others:
- •(a) IT strategist — plans the information system strategy that puts IT to work for the business strategy, and the overall computerisation plan
- •(b) System architect — designs the architecture of an information system that meets the requirements, and leads its development technically
- •(c) System analyst — analyses business operations and needs and defines what the system must do, bridging users and developers
Key rule: Finding new value in big data with statistics and machine learning is the data scientist's task; the IT roles plan (strategist), define (analyst) or design (architect) systems.
