Six Sigma is one of the most popular quality methods. It utilizes a statistical unit of measurement to measure the capability of the process, then achieve defect free performance, and ultimately increase the bottom-line and customer satisfaction. The concept of Six Sigma can be applied in the process of quality control in general and acceptance sampling in particular. Many sampling plans have been constructed using six sigma quality levels, under the assumption that the lot size is too large or infinite. It is unconvincing to say that the lot is accepted or rejected based on a fixed sample size irrespective of the huge lot size. So, a sampling plan is required which depends on the lot size. The major objective of this paper is to determine the size of the lot of a six sigma based on double sampling plan with Poisson distribution. A table is also constructed for the easy selection of the plan.
