第1题:

(b) Discuss the relevance of each of the following actions as steps in trying to remedy performance measurement

problems relating to the ‘365 Sports Complex’ and suggest examples of specific problem classifications that

may be reduced or eliminated by each action:

(i) Focusing on and improving the measurement of customer satisfaction

(ii) Involving staff at all levels in the development and implementation of performance measures

(iii) Being flexible in the extent to which formal performance measures are relied on

(iv) Giving consideration to the auditing of the performance measurement system. (8 marks)


正确答案:
(b) Trying to focus on and improve the measurement of customer satisfaction.
This is a vital goal. Without monitoring and improvement of levels of customer satisfaction, an organisation will tend to
underachieve and is likely to have problems with its future effectiveness. Positive signals from performance measures made
earlier in the value chain are only relevant if they contribute to the ultimate requirement of customer satisfaction. Tunnel vision
and sub-optimisation are examples of measurement problems that may be reduced through recognition of the need for a
management focus on customer satisfaction. For example undue focus on the importance of maximising opening hours may
lead to lack of focus on other quality issues seen as important by customers.
Involving staff at all levels in the development and implementation of performance measures.
People are involved in the achievement of performance measures at all levels and in all aspects of an organisation. It is
important that all staff are willing to accept and work towards any performance measures that are developed to monitor their
part in the operation of the organisation and in the achievement of its objectives. This should help, for example, to reduce
gaming. At the sports complex an example of gaming might be, a deliberate attempt to understate the potential benefits of
maintaining the buildings in order to ensure that funds would be used for other purposes such as an increased advertising
budget. The directors of Astrodome Sports Ltd must recognise that leisure facilities that appear dated and in a poor state of
repair will cause customers to look for more aesthetically appealing alternatives.
Being flexible in the extent to which formal performance measures are relied on.
It is best to acknowledge that measures should not be relied on exclusively for control. A performance measure may give a
short-term signal that does not relate directly to actions that are taking place to improve the level of performance in the longer
term. To some extent, improved performance may be achieved through the informal interaction between individuals and
groups. This flexibility should help to reduce measure fixation and misrepresentation. For example the percentage increase in
the quantity of bowling equipment purchased is seen as necessarily implying increased demand for use of the bowling greens.
Giving consideration to the audit of the performance measurement system.
Actions that may be taken may include:
– Seeking expert interpretation of the performance measures in place. It is important that any audit is ‘free from bias’ and
conducted independently on an ‘arm’s length’ basis. Thus it is essential that such audits should be ‘free from the
influence’ of those personnel involved in the operation of the system.
– Maintaining a careful audit of the data used. Any assessment scheme is only as good as the data on which it is founded
and how this data is analysed and interpreted.
The above actions should help, in particular, to reduce the incidence and impact of measure fixation, misinterpretation and
gaming.
For example, an audit may show that the directors of Astrodome Sports Ltd are fixated on equipment availability and
misinterpret this as being the key to customer volume and high profitability. The audit may also provide evidence of gaming
such as a deliberate attempt to underplay the benefits of one course of action in order to release funds for use on some
alternative.

第6题:

Note: requirement (a) includes 4 professional marks.

A central feature of the performance measurement system at TSC is the widespread use of league tables that display

each depot’s performance relative to one another.

Required:

(b) Evaluate the potential benefits and problems associated with the use of ‘league tables’ as a means of

measuring performance. (6 marks)


正确答案:
(b) A central feature of many performance measurement systems is the widespread use of league tables that display each
business unit’s performance relative to one another. In the case of service organisations such as TSC the use of league tables
emphasises the company’s critical success factors of profitability and quality of service by reporting results on a weekly basis
at the depot level. The fact that such league tables are used by management will actively encourage competition, in terms of
performance, among depots. The individual position of a business unit in the league table is keenly observed both by the
manager of that unit and his/her peers.
In theory, performance is transparent. In practice although each depot performs essentially the same function and is subject
to the same modes of measurement, circumstances pertaining to different business units may vary significantly. Some depots
may be situated near to the hub (main distribution centre), some may be located far away and some may be in urban zones
with well developed road networks whilst others may be in remote rural areas. Measuring performance via a league table
makes no allowance whatsoever for these relative differences, hence, inequality is built into the performance measurement
system.
Moreover, depot managers might be held responsible for areas over which they have no formal control. The network nature
of the business suggests that there will be a high degree of interdependence of depots; the depot responsible for collection
will very often not be the depot responsible for delivery. Therefore, it is frequently the case that business may be gained for
which the collecting depot receives the revenue, but for which the delivering depot bears the cost. Obviously this impacts
upon the profit statements of both depots. The formal system might not recognise such difficulties, the corporate view being
that ‘the business needs to be managed’; the depots should therefore see any such anomalies as mild constraints to work
around rather than barriers to break down. In such circumstances delivering depots and collecting depots should discuss such
problems on an informal basis. Such informal discussions are aided by close communications between depots recognising
the interdependencies of the business.
