Answer to YourTurn 1-1: Being anAnalyst
Student answers will vary, depending on their preferences regarding being a: 1) systems
analyst, 2) business analyst, 3) requirements analyst, 4) infrastructure analyst, or 5)
change management analyst. Verify that the student has correctly associated the skills
needed with the type of analyst for which they aspire and that the student has created a
plan to acquire those skills. The roles and the names used to describe them may vary
from organization to organization.
Answer to YourTurn 1-2: Implementinga Satellite Data Network
While answers may vary, answers might include the following:
1. A cost-benefit analysis, along with other financial processes (ROI, etc.) would
certainly reveal that a just-in-time (JIT) inventory can reduce inventory costs and
increase revenue. A standard communication line, encrypted or not, would not be
able to handle the high bandwidth needed for data, voice and video transmissions.
2. A competitor would be able to narrow the gap by adopting the JIT type of
inventory management. Voice and video are not necessary to keep the inventory
up to date on a timely basis, data transmissions alone would work well.
