第3题:

(c) Suggest ways in which each of the six problems chosen in (a) above may be overcome. (6 marks)


正确答案:
(c) Ways in which each of the problems might be overcome are as follows:
Meeting only the lowest targets
– To overcome the problem there must be some additional incentive. This could be through a change in the basis of bonus
payment which currently only provides an incentive to achieve the 100,000 tonnes of output.
Using more resources than necessary
– Overcoming the problem may require a change in the bonus system which currently does not provide benefit from any
output in excess of 100,000 tonnes. This may not be perceived as sufficiently focused in order to achieve action. It may
be that engendering a culture of continuous improvement would help ensure that employees actively sought ways of
reducing idle time levels.
Making the bonus – whatever it takes
– It is likely that efforts to change the ‘work ethos’ at all levels is required, while not necessarily removing the concept of
a bonus payable to all employees for achievement of targets. This may require the fostering of a culture for success within
the company. Dissemination of information to all staff relating to trends in performance, meeting targets, etc may help
to improve focus on continuous improvement.
Competing against other divisions, business units and departments
– The problem may need some input from the directors of TRG. For example, could a ‘dual-cost’ transfer pricing system
be explained to management at both the Bettamould division and also the Division with spare capacity in order to
overcome resistance to problems on transfer pricing and its impact on divisional budgets and reported results? In this
way it may be possible for the Bettamould division to source some of its input materials at a lower cost (particularly from
TRG’s viewpoint) and yet be acceptable to the management at the supplying division.
Ensuring that what is in the budget is spent
– In order to overcome the problem it may be necessary to educate management into acceptance of aspects of budgeting
such as the need to consider the committed, engineered and discretionary aspects of costs. For example, it may be
possible to reduce the number of salaried staff involved in the current quality checking of 25% of throughput on a daily
basis.
Providing inaccurate forecasts
– In order to overcome this problem there must be an integrated approach to the budget setting process. This may be
achieved to some extent through all aspects of the budget having to be agreed by all functions involved. For example,
engineers as well as production line management in reaching the agreed link between percentage process losses and
the falling efficiency of machinery due to age. In addition, TRC may insist an independent audit of aspects of budget
revisions by group staff.
Meeting the target but not beating it
– To overcome the problem may require that the bonus system should be altered to reflect any failure to control costs per
tonne at the budget level.
Avoiding risks
– In order to overcome such problems, TRC would have to provide some guarantees to Bettamould management that the
supply would be available during the budget period at the initially agreed price and that the quality would be maintained
at the required level. This would remove the risk element that the management of the Bettamould division may consider
currently exists.
