Simplified Approach to Probabilistic Cost Benefit Analysis: Architectural Lighting Example - Cost benefit analysis is a well established technique for assessing the economic viability Of Projects. With the increased focus on efficiency, the use of cost benefit analysis has grown significantly across various disciplines. Several software tools have been developed specifically for professionals wanting to use that technique. Probabilistic cost benefit analysis has gained some ground as a tool that can handle uncertainty and risk.

This article describes a practical simple approach to perform probability cost benefit analysis using spreadsheets.
CPM Scheduling -- How Industry Views Its Use - Experience over the past 20 years has demonstrated that a well developed, updated and consistently used critical path method (CPM) schedule during a project can increase the probability of a project finishing on time and-or assisting in party-agreed extensions of time. An accurate, consistently used and updated CPM schedule allows either party to demonstrate the history of how the project was executed and if delays occurred to the project, when, where and what activities were specifically impacted by these delays. Demonstrating how a project was executed and what was critical at the time can be especially useful when resolving disputes that may arise as the project progresses, not just at project completion.
