The Fortified High Energy Biscuits analysed data collected from Institute of Food Science and Technology (IFST), BCSIR, Dhaka by Single Stage Cluster Sampling method over the year from 2007 to 2012. The process capability analysis as a means of decision making in manufacturing company was aimed, to investigate whether the production process is in control, to investigate whether the specification limit of the company is properly centred, to examine the process capability of the company and to state if the process is capable or not. Also the analysis of process capability was used. It was discovered that the specification limit of the company is not properly centred i.e. off centred. It is recommended that in order to achieve continuous improvement of the process, the company should always attempt to redefined the voice of the process to watch and them to surpass the expectation of the customers. Also, the institutional specification limit should be redefined to be properly centred and to meet customer requirement.

Keywords: Process capability analysis; Specification limit; Voice of the process; Properly centred; Single Stage Cluster Sampling.
