Section B - Case 2: BioGrow Agriculture

BioGrow is an agricultural company producing a premium organic fertilizer. The standard material mix for one batch of fertilizer is:

  • Material Alpha: 60 kg at $10 per kg
  • Material Beta: 40 kg at $15 per kg

During the last month, BioGrow produced several batches. The actual total input was 10,000 kg of material, consisting of:

  • 5,500 kg of Material Alpha
  • 4,500 kg of Material Beta

Calculate the total material mix variance in dollars. (Enter the numerical value only. Assume the variance is Adverse, do not enter 'A' or 'Adverse')

Section B - Case 2: BioGrow Agriculture

BioGrow is an agricultural company producing a premium organic fertilizer. The standard material mix for one batch of fertilizer is:

  • Material Alpha: 60 kg at $10 per kg
  • Material Beta: 40 kg at $15 per kg

At the end of the year, BioGrow decides to split its total material price variance into a 'planning variance' and an 'operational variance' because global commodity prices for Material Alpha unexpectedly surged due to a supply chain crisis.

Which TWO of the following statements regarding planning and operational variances are correct?

Answer options:

A.

The planning variance reflects the difference between the original standard and a revised standard based on uncontrollable market changes.

B.

The operational variance is a better measure of the purchasing manager's actual performance.

C.

The planning variance is always controllable by operational management.

D.

Splitting variances into planning and operational components is only applicable to material costs, not labor or overheads.

How to approach this question

Recall the definitions and purposes of planning vs. operational variances.

Full Answer

Planning variances arise because the original standard is no longer realistic due to external factors (Option A). By removing this uncontrollable element, the remaining operational variance compares actual performance against a realistic, revised standard, providing a much fairer assessment of the manager's performance (Option B).

Common mistakes

Assuming planning variances are controllable by operational managers.
