In the context of selecting audit procedures, ensuring that sufficient evidence will be collected is critical for a few reasons. Gathering adequate evidence is fundamental to establishing the reliability of audit findings and conclusions. An IS auditor must apply professional judgment to determine the type and extent of evidence necessary to appropriately assess the effectiveness of controls and the accuracy of financial reporting.

By ensuring that sufficient evidence is collected, the auditor can substantiate their assessments regarding risks and controls within an organization. This thoroughness is essential for providing stakeholders with a fair evaluation of the information systems and processes being audited. Having robust evidence allows the auditor to draw valid conclusions and make informed recommendations, which ultimately enhances the audit's effectiveness.

While the other options are important aspects of the auditing process, they do not directly relate to the primary aim of collecting evidence. Adequate time allocation, understanding client operations, and compliance with legal standards, while still significant, are secondary considerations compared to the critical requirement of gathering sufficient evidence to support the audit's conclusions and recommendations.
