The researcher of Asian Composites Manufacturing Sdn. Bhd. (ACM) are currently doing a research on how to
reduce waste within all processes in an activity duration of the production, in order to increase profit for the
company. Currently, the duration of the activity processes was recorded by manual procedure in paper-based form
which are prone to many problems. At the same time, it lacks in real-time feedback between the researcher and the
staff of ACM. To overcome these problems, the Online Activity Duration Management System (OADMS) is proposed.
This system will computerize the manual procedure. It is provided in a web-based environment. The OADMS system
is developed by using the waterfall system development methodology, while the programming languages are using
Hypertext Markup Language (HTML), Hypertext Preprocessor (PHP), Structured Query Language (SQL) and
JavaScript. The OADMS provided a systematic activity duration management for staff of ACM and eased the works
of researcher in analyzing the processes and providing feedbacks for improvements of the activity duration. By,
providing a computerized solution, it is concluded that the activity duration management is more systematic and
precise.
