b.
The two specific items in the case that deal directly with this are the material savings and
the strike. The estimated cost of the strike can be computed as:
400 baskets x $12.40 (budgeted contribution margin)
We can think about including lost sales even though she sold the planned 8,000. She
might have been able to sell (and produce) more if there was no strike.
The materials savings of $8,000 (= 20% $5 8,000 units) are already incorporated in
the total material efficiency variance. There is no reason she should receive credit for
these and not be held responsible for the other efficiency losses.
c.
Certainly Mary is not responsible (in the sense of control) for the strike. However, she is
responsible for designing operations and selecting suppliers. Strikes are not unknown and
if she is not held accountable for the effect of strikes (or fires, or floods, etc.), she will not
include the possible costs in her decisions.
Should the contract be re-negotiated? This is a much more difficult question. There are (at
least) two factors that need to be considered here. First, since this is the first year of
operations, the budget against which Mary is evaluated is subject to a great deal of
uncertainty. That is, the benchmark might have been “wrong.” On the other hand, if the
contract is re-negotiated for this event, how effective can the budget be in the future?
