| Abstract | ||
| The research aimed to measuring and analyzing the capability of the process in order to stand on the possibility of the process to achieve design specifications "or so-called customer requirements." Where the research relying in the measurement and analysis of the process capability on the indicators capability process that it calls the " Capability Indexes" . where the researcher measured capability process for the production of plastic pipes to withdraw (20) samples (k) and every subgroup consisting of (4) parts (n) drawn over time of shit for a month period . Data were analyzed for the purpose of finding the mean, range and control limits the upper and lower of the process, and then mapping the middle and range to see the controlling process condition, and the computing of process capability and graphic curve of normal distribution of the process as well as find the index process capability to judge the status of the operation. The research found that the process is under control, but the process is not capability. The researcher proposed to reduce variation process to search for the causes of deviation process, whether the common cause of (random variation which is normal in the design process itself) or a special cause (non -random variation, which can be attributed to causes assign ability such as poor raw material, lack of experience and skill individual worker, or inappropriate environmental conditions or no making the procedures of appropriated ) . | ||
