	abstract = {In practice, Process capability indices such as lifetime performance index C<sub>L</sub> indicate the relationships between the actual process performance and the manufacturing specifications, where <em>L</em> is the lower specification limit and it is known. Progressive first-failure censoring scheme is quite useful in many practical situations where lifetime of a product is quite high and test facilities are scarce but test material is relatively cheap. This study, under the assumption of two-parameter exponential distribution and by applying data transformation constructs a uniformly minimum variance unbiased estimator (UMVUE) of C<sub>L</sub> based on a progressive first-failure censored sample. Then the UMVUE of C<sub>L</sub> is utilized to develop the new hypothesis testing procedure. Finally, two illustrative examples are given to assess the behavior of this test statistic for testing null hypothesis under given significance level.},
