Information Systems development: time network planning G. ~aramis' & Th. Fotiadis 1 University of Macedonia, Thessaloniki, Greece Abstract For a complete and foolproof control for the development of an Information System (IS) there arises a need for proper time planning of the relative activities, which is achieved by the "diagram" depiction of the "time arrangements" of these activities (Bar Charts, CPM, PERT). In this paper there are briefly presented, a Bar Chart and a model of the network CPM for the time scheduling of the IS'S development. Furthermore, with the use of the Beta Distribution what is achieved, is the Theoretical Distribution of Frequency of the Time Development of the IS. Thus, the design of the equivalent network PERT is easy, and as a result with the contribution of PERT and of the Central Limit Theorem, the assessment of the possibility of development of IS within the planned time is attempted. 1 Introduction Time planning was initially applied during the procedures for
