Which statement best describes why a manager might investigate only variances exceeding a set threshold, such as 5% of standard?

Using a threshold such as 5% applies management by exception: managers investigate only significant deviations from standard, saving time and focusing on problems, rather than reviewing every small variance.

  1. AIt applies management by exception, focusing attention on significant deviationsCorrect
  2. BIt ensures all favourable variances are treated as adverse for prudence
  3. CIt removes the need for standards to be revised
  4. DIt guarantees that variances are controllable by the manager

Explanation

Thresholds support management by exception: only variances large enough to matter are investigated, saving time. They do not change how variances are classified, remove the need to revise standards, or make variances controllable.
