Based on the interviews to the client and a thorough assessment of the manual process of determining the productivity level among PLDT employees, the functionalities needed for the proposed system has been identified. Higher programming languages and web development tools have been utilized in the development of the system. Post-evaluation was conducted to determine the performance of the developed system at PLDT Malolos Branch. Based from the finding on the post-evaluation of the productivity monitoring system, major finding showed that the installed system was “highly acceptable ” based on ISO 9126 Software Quality Assurance Model in terms of functionality, accuracy, user-friendliness, reliability and security.
