The quality of product and testProduct : things gotten by voluntary labor.: Test (Japanese say it experiment ):: An activity which can be and need to be repeated ? Purpose: For testing a theory or improving an index“product"、"test" are generalized..Quality of the product is the sum of design qualityand production quality2007.462

2 2007.4 The quality of product and test Product : things gotten by voluntary labor. • Test (Japanese say it experiment ): • An activity which can be and need to be repeated， • Purpose: For testing a theory， or improving an index. •“product” 、 “test” are generalized. •Quality of the product is the sum of design quality and production quality

A test is reasonableif it can be achieved repeatlycan be teached,works effectively2007.43

3 2007.4 A test is reasonable, if it can be achieved repeatly, can be teached, works effectively

Test designIn order to reach the goal faster, cheaperand more reasonable.Test need to be designedAll method,theory and application of thesubject are combined to thetest design2007.4

4 2007.4 Test design In order to reach the goal faster, cheaper and more reasonable. Test need to be designed. All method,theory and application of the subject are combined to the test design
