A consequence of JIT purchasing and production is that sometimes the purchase
price for raw materials or the production cost for finished goods may be higher
than they might otherwise be, because a supplier may charge a higher unit price
for a small quantity. Production costs per unit may also be higher when batch
sizes are smaller. With variance reporting, the aim would be to reduce material
price variances and production cost variances; however in a JIT environment, it
is considered that other benefits – not measured in variances – are greater.
Variance reporting could therefore be inconsistent with JIT.
4.3 Standard costs in a rapidly-changing environment
Some business entities operate in a business environment where change is continual
and fast. The life cycle of products may be short because of rapidly-changing
technologies, and products may be developed or re-designed regularly, with new
production methods. As new technologies develop and become popular, the market
size might grow but sales prices are likely to fall.
There are many examples of industries in a rapidly-changing environment; for
example mobile phone technology has changed enormously within a relatively
small number of years, so that we now have touch screen technology and small
handsets. Over time, the materials content of mobile phones has diminished, sales
volumes have rocketed and sales prices have fallen substantially.
Standard costs may be incompatible with rapid change, for similar reasons to those
explained for TQM.
With variance analysis, actual results are compared with a fixed standard and a
budget, and variances arise when actual results differ from the standard or
budget.
In a rapidly-changing environment, it should be expected that the original
standard or budget may get out of date, and action to try to eliminate an adverse
variance may in fact be inappropriate because operating conditions have now
changed.
In conclusion, it may be argued that standard costing and variance analysis are now
much less important for budgetary control than they may have been in the past.
Standard costing and variances are most useful in conditions where standard
products are made and sold. However, many companies now produce non-
standard products, and try to adjust their products to the individual needs of
particular customers. Even where companies do not customise products for
individual customers, there is extensive fragmentation of markets into segments
or niches, with different product designs manufactured for each separate
segment.
As suggested above, variance reporting and budgetary control based on
variances may not be appropriate for many modern manufacturing
environments, such as those where TQM or JIT methods are applied.
Similarly, variance reporting may be inappropriate in a rapidly-changing
business environment.
