producing a product from the manufacturer’s
point of view
Value for money is:

Consumer Criteria for
Evaluation

Consumers apply criteria for evaluation to
determine value for money. This occurs:

Before Purchase – advertising,
manufacturers specification, list price,
product image, evaluation by experts and
consumer groups.
Purchase
 Aesthetics
 Performance
 Build
quality
 Purchase price
Initial use
 Actual
performance
 Safety
 Ease
of use
Long term use

Reliability
Ease of maintenance
Durability
Running costs.
How often have you bought a new gadget
based purely on its aesthetic appearance.
Evaluation based on Initial use

New Sony Eriksson walkman phone (W800i)
Purchase based on evaluation of aesthetics.
The evaluation after initial use is the buttons

Size – compact
Colourful – aesthetics
Reliability: battery lasts a long time
compared to mobile phone.
Durability: Lasts approximately 1 year,
battery then becomes unreliable.
Ease of maintenance – Simple to maintain
and use, just simply re-charge and you can
charge while listening to music.
Running costs – low, you can recharge in
the mains electrical supply or through your
computer.
Value Judgements
This plays a part in product analysis, and can
vary according to:

Quality Assurance

Means that the consumer does not have to
carry out their own research into the quality of
the product and components. They have a
means of re-dressing if a product fails to
meet an expected standard for example, via
a guarantee.
Consumer Associations


These are independent organisations which
carry out tests on products to see if
manufacturers claims are justified, and
provide published data for consumers. They
compare similar products within a target
market and recommend the best value-formoney products.
