Title: IB Design and Technology Evaluation

IB Design and Technology Evaluation
  • Evaluation and the consumer

Some initial definitions
  • Cost effectiveness is
  • The most efficient way of designing and producing
    a product from the manufacturers point of view
  • Value for money is
  • A concept that takes account of the relation
    between what something (a product) is worth and
    the cash amount spent on it.

Comparison of price and value
  • If the price is too high there may not be enough
    potential purchasers.
  • If the price is too high purchasers who can
    afford the product may be a select few.
  • Consumer may not think the product is value for
    money if the price is too high.

Comparison of price and value
  • If the price is too low consumers may think the
    product is too cheap to have much value.
  • Demand for products will establish the maximum
  • The costs of production will determine the
    minimum price.
  • A company may choose to set its price in
    accordance with the perceived value of a product
    or in relation to competitors.

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.

  • 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 are too small
    and the batteries dies.

Evaluation of long term use I pod mini
  • 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
  • The individual
  • The time (era)
  • Circumstances

Value judgements - Consumers
  • The judgements the consumer makes will differ
    from those made by the designer. Consumers often
  • Utility
  • Security
  • Reliability
  • Rarity
  • Aesthetics

Value judgements - Designer
  • Function
  • Reliability
  • Ease of maintenance

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-for-money products.

    journals and design education in schools when
    educating the consumer about new products.
