The use of statistical process control techniques in the web application products

The fast development and use of IT and customer interactive websites has created great opportunities for enterprises involved in developing web application product in project-oriented environment. Many projects fail due to lack of clear identification of customer requirements, and lack of control of defects, especially when the defects have different weights according to their severity (effects) on the acceptance of the products. In this paper, we will firstly classify the severity of defects, secondly define the sign-off criteria for web-based application, and finally, determine whether the process is in statistical control using the demerits chart (U-chart), process capability analysis and fish bone diagram.
