Administration QUESTION #9606

Question 1496

An organization restructures from a tall hierarchy (7 levels) to a flat structure (3 levels) and simultaneously widens every manager's span of control from 5 to 15 subordinates. Six months later, managers report overload and junior employees report feeling unsupervised. Which organizational design principle was violated, and what contingency factors should have been assessed before restructuring?

The principle of unity of command — multiple reporting relationships have confused authority lines after flattening
The span of control principle — effective span is not uniform but depends on task complexity, subordinate competence, degree of task interdependence, and clarity of plans; widening span without first ensuring these contingency conditions are met creates supervisory overload and performance gaps✔️
The scalar principle — the reduction in hierarchical levels has broken the chain of authority from top to bottom
The departmentalization principle — flattening without changing departmental groupings produces functional conflicts

Correct Answer Logic:

Span of control theory (Graicunas, Urwick) holds that effective span depends on: task complexity (complex tasks require more supervisory interaction), subordinate training (trained subordinates need less supervision), task interdependence (interdependent tasks require more coordination), and plan clarity (clear procedures reduce supervisory burden). Widening span to 15 without addressing these factors creates the exact failure described. Restructuring must be preceded by contingency assessment, not driven solely by cost-reduction logic.

Question 1497

Notes: Gregorian calendar (365 days) causes dates to fall on different weekdays each year. Hanke-Henry calendar (364 days) has dates on same weekday each year, supporting predictable scheduling. Which choice explains an advantage of Hanke-Henry?

Gregorian has 365 days, one day longer than Hanke-Henry.
Adopting Hanke-Henry would help solve a problem with Gregorian.
Designed so dates occur on same weekday each year, Hanke-Henry supports more predictable scheduling than Gregorian.✔️
Hanke-Henry was developed as an alternative to Gregorian, which is most-used.

Correct Answer Logic:

Option C directly states the advantage (same weekday ? predictable scheduling) and compares to Gregorian.

Question 1499

In the decimal system (base-10), which statement is CORRECT?

You can use digits 0 through 8 only (9 digits total)
You can use digits 0 through 9 (10 digits total)✔️
You can use digits 1 through 10 (10 digits total)
You can use digits 0 through 10 (11 digits total)

Correct Answer Logic:

In the decimal system, there are exactly 10 possible digit symbols ranging from zero (0) to nine (9). The number 10 itself is NOT a single digit — it is composed of two digits (1 and 0). This is why the system is called 'base-10'.
