ITPEC IP October 2019 Question 84
Although a data warehouse is put into operation, it is seldom used. As a result of user interviews, it is concluded that the users’ skill level is lower than expected. Which of the following is an appropriate plan to promote the utilization of the data warehouse?
Explanation
Preparing standard templates for data extraction and analysis patterns — it removes the obstacle the interviews found, the users' low skill.
The data warehouse works, but users cannot extract and analyse the data themselves. A measure that promotes use must make the work possible at their skill level. Ready-made templates for the common extraction and analysis patterns let users get results by choosing a template and filling in conditions, without building queries from scratch.
Answer (b)
Why not others:
- •(a) — a notice through managers pushes people to use the system but does not give them the skill to do so
- •(c) — fresher, real-time data improves the data, which was not the problem; users still cannot analyse it
- •(d) — adding more information makes the warehouse larger and harder to use, which works against users with low skill
Key rule: To promote use of a system, address the cause found in the investigation; when the cause is users' skill, simplify the task or train them rather than change the data.
