Comprehensive and Detailed In-Depth Explanation:
E-commerce systems that automate purchasing and billing typically lead to:
Faster procurement cycles due to automated ordering.
Increased accounts payable, as more transactions are processed quickly.
Option A (Higher cash flow) - Unlikely, since faster billing does not always improve cash flow.
Option B (Higher inventory balances) - Incorrect, as e-commerce often enables just-in-time inventory.
Option C (Higher accounts receivable) - E-commerce speeds up collections, reducing receivables.
Since automated purchasing increases outstanding payments, Option D is correct.

Human resources (HR) best supports the internal audit function by facilitating candidate sourcing through recruiting platforms, networks, and agencies. This broadens the pool of qualified applicants. The CAE and audit function should retain responsibility for assessing audit-specific skills and selecting the best candidate.
Option A may be part of HR's role but competency evaluation is more specialized for audit. Option C is administrative, not strategic. Option D improperly delegates candidate selection to HR instead of the CAE.

Understanding Resource Coordination in Project Management:
Resource coordination involves assigning and managing human, financial, and technological resources to ensure the project runs smoothly.
The Execution phase is when project plans are implemented, and resources are actively utilized.
Why Execution?
During execution, the project manager must coordinate resources, monitor performance, and resolve conflicts to keep the project on track.
This phase involves managing teams, distributing tasks, and ensuring resources are used efficiently.
Why Other Options Are Incorrect:
A). Initiation: Focuses on defining project objectives, scope, and feasibility but does not involve active resource coordination.
B). Planning: Deals with creating resource allocation plans but does not handle real-time coordination.
D). Monitoring: Involves tracking performance and making adjustments but does not actively assign or manage resources.
IIA Standards and References:
IIA Practice Guide: Auditing Project Management (2020): Recommends evaluating resource management practices during the execution phase.
IIA Standard 2110 - Governance: Internal auditors should ensure project resources are managed effectively to achieve objectives.
PMBOK Guide - Project Resource Management: Specifies that resource coordination primarily happens in the execution phase.

The most effective way to ensure adherence to updated methodologies is through training that reviews and explains the changes in detail. A recorded training session allows all auditors to learn consistently and revisit the content as needed.
Option A improves accessibility but does not ensure understanding or compliance. Option B documents acknowledgment but does not ensure comprehension. Option D provides awareness but lacks sufficient depth.

Comprehensive and Detailed In-Depth Explanation:
The cash conversion cycle (CCC) is calculated as:
CCC=Days Inventory Outstanding+Days Sales Outstanding#Days Payables Outstanding\text{CCC} = \text
{Days Inventory Outstanding} + \text{Days Sales Outstanding} - \text{Days Payables Outstanding} CCC=Days Inventory Outstanding+Days Sales Outstanding#Days Payables Outstanding CCC=58+42#10=90 daysCCC = 58 + 42 - 10 = 90 \text{ days}CCC=58+42#10=90 days Option A (26 days) - Incorrect, as it does not account for total cycle components.
Option C (100 days) & Option D (110 days) - Overestimate the cycle by not correctly adjusting for payables.
Thus, Option B (90 days) is the correct answer.
