Final answer:
When deciding whether to investigate a variance, factors such as magnitude, trend, and likelihood of reducing future occurrences should be considered, but whether the variance is favorable or unfavorable should not be a factor.
Step-by-step explanation:
When deciding whether to investigate a variance, there are several factors to consider. However, the factor that should NOT be considered is whether the variance is favorable or unfavorable. This is because investigating a variance is not dependent on its direction but rather on the impact it has on the business processes.
The other factors that should be considered are:
- Magnitude of the variance: It is important to assess the significance of the difference between the expected and actual outcomes.
- Trend of the variances over time: Analyzing the trend can help identify patterns and potential underlying causes.
- Likelihood that an investigation will reduce or eliminate future occurrences of the variance: If investigating the variance can lead to process improvements or prevent future deviations, it is worth considering.
