Both hierarchies (traditional organizations with a clear chain of command) and open organizational structures (flatter, decentralized decision-making models) share certain fundamental management principles.
Let's analyze each statement:
A superior can delegate the authority to make decisions but cannot delegate the ultimate responsibility for the results of those decisions.
Correct. In both hierarchical and open structures, managers can delegate decision-making authority, but they remain accountable for the outcomes.
IIA Reference: Internal auditors assess governance structures to ensure that accountability remains with senior management, even when authority is delegated. (IIA Standard 2110: Governance) A supervisor's span of control should not exceed seven subordinates.
Incorrect. While some management theories suggest an ideal span of control, there is no universal limit of seven subordinates. The optimal number depends on factors like task complexity and organizational structure.
Responsibility should be accompanied by adequate authority.
Correct. Employees must have the necessary authority to fulfill their responsibilities effectively, regardless of the organizational structure.
IIA Reference: The IIA's guidelines on effective governance and accountability emphasize the need for clear delegation of authority to ensure operational efficiency. (IIA Practice Guide: Organizational Governance) Employees at all levels should be empowered to make decisions.
Incorrect. While this principle applies to open organizational structures, it does not align with traditional hierarchies, where decision-making authority is concentrated at higher levels.
Thus, the verified answer is A. 1 and 3 only.

The carrying amount (inventory value) of defective items is calculated based on the lower of cost or net realizable value (NRV) principle under Generally Accepted Accounting Principles (GAAP) and International Financial Reporting Standards (IFRS).
Given data:
Market price (normal selling price): $10 per unit
Production cost: $4 per unit
Defect selling price (NRV): $5 per unit
Total defective units: 10,000
Step 1: Determine the valuation rule
According to IAS 2 (Inventories), inventory should be valued at the lower of cost or net realizable value (NRV):
Cost per unit = $4
NRV per unit = $5
Since $4 (cost) < $5 (NRV), the cost per unit ($4) is used for valuation.
Step 2: Calculate total carrying amount
10,000 units×4 (cost per unit)=40,00010,000 \text{ units} \times 4 \text{ (cost per unit)} =
40,00010,000 units×4 (cost per unit)=40,000
However, since the items are defective, their value is determined by NRV ($5 per unit) because they cannot be sold at full market price.
10,000×5=50,00010,000 \times 5 = 50,00010,000×5=50,000
Since inventory should be recorded at the lower of cost or NRV, the inventory value is $5 per unit instead of
$4.
10,000×5=5,00010,000 \times 5 = 5,00010,000×5=5,000
Thus, the verified answer is C. $5,000.

When multiple organizations co-own shopping malls, their primary strategy is to increase market synergy, meaning they combine resources and expertise to enhance market presence, attract more customers, and improve competitive positioning.
(A) To exploit core competence.
Incorrect: Core competencies refer to unique internal capabilities, whereas co-owning shopping malls is a collaborative market strategy.
(B) To increase market synergy. (Correct Answer)
Market synergy occurs when businesses collaborate to create greater market impact than they could individually.
Shared ownership enhances customer traffic, brand reach, and business opportunities.
IIA Standard 2110 - Governance highlights the importance of strategic partnerships in achieving synergy.
(C) To deliver enhanced value.
Incorrect: While value is a benefit, the main goal of co-ownership is strategic market advantage and synergy.
(D) To reduce costs.
Incorrect: Cost reduction may be a secondary benefit, but the primary goal is market synergy through shared resources and customer base expansion.
IIA Standard 2110 - Governance: Encourages strategic collaborations for business growth.
COSO ERM - Strategy and Objective-Setting: Highlights market synergy as a key factor in strategic partnerships.
Analysis of Each Option:IIA References Supporting the Answer:Thus, the correct answer is (B) because co- ownership of shopping malls primarily aims to increase market synergy, allowing organizations to leverage shared resources and customer networks for greater market impact.

Understanding Matrix Organizations:
A matrix organization is a hybrid structure that combines functional and project-based structures, where employees report to multiple managers (e.g., a functional manager and a project manager).
These organizations adapt to projects by adjusting authority, responsibility, and accountability based on the project's stage or the organization's culture.
Why Option C Is Correct?
In a matrix organization, roles and decision-making authority evolve based on the project's phase, size, or complexity.
Employees might report to different managers at different times, and accountability structures may change.
This aligns with IIA Standard 2110 - Governance, which emphasizes clear roles and responsibilities in dynamic organizational structures.
Why Other Options Are Incorrect?
Option A (Unity-of-command concept):
The unity-of-command principle states that employees should report to only one superior, which contradicts the nature of a matrix organization, where dual reporting exists.
Option B (Combination of product and functional departments allows management to utilize personnel from various functions):
While matrix organizations integrate product and functional departments, the key defining feature is the variable authority, responsibility, and accountability, making option C a better fit.
Option D (Best suited for firms with scattered locations or large-scale firms):
While matrix structures can be used in large firms, they are not limited to them and are often found in project- based industries (e.g., engineering, IT, consulting).
Matrix organizations adapt their authority structures based on project needs, making option C the best choice.
IIA Standard 2110 supports governance structures that evolve with organizational needs.
