Within enterprises, which functional areas have historically shown the strongest interest in functional information systems (department-focused MIS)?

Introduction / Context:
Functional information systems are specialized MIS solutions supporting a specific department’s workflows and decisions. Historically, finance and manufacturing were early adopters due to clear data structures, measurable outcomes, and strong ROI cases.

Given Data / Assumptions:

• Finance needs include GL, AP/AR, budgeting, and compliance reporting.
• Manufacturing needs include MRP, scheduling, inventory, and quality control.
• We are identifying areas with strongest, early, and ongoing interest.

Concept / Approach:

Step-by-Step Solution:

Verification / Alternative check:

Why Other Options Are Wrong:
Selecting only one omits the other significant adopter; “neither” contradicts historical adoption patterns.

Common Pitfalls:
Undervaluing other functions like marketing and HR; however, finance and manufacturing remain principal early drivers.

Final Answer:
both (a) and (6)
