Planning and control of the introduction of a closed numbering system for telecommunications in Sri Lanka - a novel approach

Abstract

The author first started with the research "Information Management of Telecommunication Development Projects". After working on it for an year the author came to a dead-end. At this point the author was handling the numbering project (Introduction of a Closed Numbering System for Telecommunications in Sri Lanka) at the Telecommunications Regulatory Commission of Sri Lanka (TRCSL). At this point also the author was introduced to an Information Modeling Technique called Data Flow Diagramming. Having obtained prior approval from the Commission to use the Numbering Project as her research, the authors' intention was to create an implementation schedule for the Numbering Project. In order to create an implementation schedule, first what is called a Work Breakdown Structure (WBS) had to be prepared. Having studied the literature on Data Flow Diagramming (DFD) the term 'exploding used in DFD's and WBS gave the author the idea to create a WBS using DFD's. After creating the initial DFD'S the author interacted with users of the implementation schedule in order to create a set of final and accurate DFD'S. After creating the DFD's, the WBS and a Gannt Chart (Implementation Schedule) were prepared using the levels and numbering scheme used in the DFD's. The methodology, findings and the author's recommendations are given in chapters 5 & 6. The author also carried out literature surveys on Telecommunication Numbering, the present & new Numbering Plans of Sri Lanka, Conventional Project Planning and Control Techniques and Information Modeling. These are presented in Appendix D and chapters 2, 3, 4 respectively.
