参考答案：D

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.
