This paper proposes DASP and SASP based on Lifetime life test when a product's life follows an exponential Weibull distribution using a two-point approach (consumer risk and product risk). Suggested dual sampling and individual sampling plans were submitted, assuming a two-point approach design assumes that the product life follows ETW distribution. It was found that the dual sampling plan may be more economical than the individual sampling plan which gives a lower quality level. As the savings in the sample size increase with the double sampling plan with the decrease in consumer risks.
