Web-Based Telephone Extension Directory System For Menara Celcom

Today, many organizations just resort to provide telephone extension directory of their employees in the form of manual lists. When this happens, these employees might have difficulty in accessing the telephone extension directory in an efficient manner. Thus, this study aims
to propose a solution to the manual lists of telephone extension directory which are currently provided by Celcom to its employees at Menara Celcom. The proposed solution is to come out with a web based telephone extension directory system that can be efficiently managed by the secretaries and accessed by its employees. Based on the identified functionalities from other web-based applications, a requirement model consisting of Use Case Diagram and Class Diagram has been produced to design the prototype of the proposed system. A data model consisting
of Entity Relationship Diagram and Data Dictionary has also been produced to model the database components of the prototype. The prototype, named as Telephone Extension Directory System (TEDS), has been tested by all the fifteen (15) divisional secretaries and a total of forty (45) staff randomly selected from different division, department and position. The focuses of the tests are to validate (1) the identified functionalities, (2) functions that can minimize/eliminate typing mistakes when adding, deleting or editing records, (3) functions that can perform
searching operations satisfactorily for users. In overall, the prototype has passed all of these tests with excellent scores.
