HR-related information systems scope: Personnel Administration data systems, Personnel Planning data systems, and the Payroll system all share what capability in common?

Introduction / Context:
Human Resources (HR) technology spans multiple subsystems. Personnel Administration maintains employee master data, Personnel Planning supports workforce planning and succession, and Payroll computes compensation and statutory withholdings. It is important to distinguish their overlapping and unique functions.

Given Data / Assumptions:

• Personnel Administration: demographic data, employment status, job codes.
• Personnel Planning: modeling headcount needs, skills, and succession.
• Payroll: wage calculation, deductions, and net pay.
• The question asks for a capability common to all three listed systems.

Concept / Approach:
Only Payroll calculates payroll deductions. Personnel Administration and Planning do not. Updating the Accounts Payable (AP) file is not a standard function of all three; payroll may post to General Ledger or create payment instructions, but AP updates are typically handled within finance modules, not by HR master or planning systems. None of these HR systems should access the inventory file, which is a logistics/operations artifact unrelated to HR.

Step-by-Step Solution:
Evaluate each proposed common capability across all three systems.Find that payroll deductions apply only to Payroll, not the other two.Note that AP and inventory access are finance and operations functions, respectively.Therefore, there is no single capability shared by all three options; choose “None of the above.”

Verification / Alternative check:
Enterprise suites (for example, ERP) keep HR, Finance, and Logistics modules logically separated with controlled integrations, reflecting this division of responsibilities.

Why Other Options Are Wrong:

• Calculate payroll deductions: Exclusive to Payroll.
• Update accounts payable file: Not a universal HR function.
• Access inventory file: Outside HR domain.
• All of the above: Incorrect since none are common to all three.

Common Pitfalls:
Assuming that being in the same ERP means identical capabilities; modules integrate but maintain distinct responsibilities.

Final Answer:
None of the above
