ABSTRACT
In this article, PERT/CPM, as conventional tools for planning and controlling are discussed along with problems accompanied with their application. This article demonstrates a number of benefits, the most significant among them being that: PERT/CPM as conventional planning techniques needs to be scrutinized. Dealing with risk management in project management is now essential for minimizing losses and to enhance profitability. Yet, using floats, as stated by the traditional resource allocation method that is applied in most of current software, now needs to be investigated. PERT/CPM techniques are very common and widely adopted management tools, currently used in the processes of project planning and control. These techniques have been widely accepted in the construction industry. Despite the use of these techniques, experience shows that construction projects failed to achieve their defined objectives with respect to time and cost.
