Despite widely-accepted project control systems utilities & ways of doing things being used to watch (for changes, unusual things, etc.) the project performance, it was seen/obvious that a large number of projects do not complete on time & within budget (For every $1 billion invested in the United States, $122 million was wasted due to missing project performance. (Source: Pulse of Profession Report 2016 PMI.org) However, Earned Value Management (EVM) ways of doing things are used to watch (for changes, unusual things, etc.) project performance the chances to have performance shortages still exist. Since most Project Managers focus only on gain & loss since EVM is cost-oriented this way most of Project managers might select wrong priorities and ignore the resource constraints and Actual site conditions.

It’s very important to successfully identify the good Projects control systems & progress review ways of doing things that promise that something will definitely happen or that something will definitely work as described the project completion on time, within budget. In order to tell apart the needed/demanded good project management solid basic structure on which bigger things can be built and sustained project controls system it is preferred to move beyond traditional scheduling processes. Usually, most of projects have no ideal conditions for the activities of many possible/likely such as but not limited to, Project complex difficulty level, useful thing/valuable supply types and site location.

The main concern of using traditional scheduling process is that most of the planners and/or schedulers ignore or do not think about/believe uncertainties.  However; PERT (The Program Evaluation and Review Technique) model is being used to calculate construction activity duration as an average of Optimistic, Pessimistic and Most likely duration of the activity. This model is being calculated to give a weighted average of activity duration it is a classic model that usually gives optimistic results. Another classic model is being used is CPM (Critical Path Method) which still ignores the previously-mentioned uncertainties. The need for change from traditional scheduling process to a modern and practical model is to think about the uncertainties that may affect the project activities estimated duration and cost also, and Project Managers with their teams have to have an agreed-upon process that allows all of the project risk areas to be uncovered, tested/evaluated and dismissed or mitigated (Pre-Mortem managerial strategy – Source Wikipedia).

The approach to this idea depends on TOC (Theory of Constraints or Explanation of why something works or happens the way it does of Restrictions) to put into use CCPM (Critical Chain Project Management) which were developed by Goldratt. This practical scheduling process applies the resource constraints on the project Critical Path to finally develop a Critical Chain.

The goal of this technical paper is to:

  • Make the case for using a scheduling technique that considers uncertainties and natural variability that may impact the project activities, especially in the construction field.
  • Highlight hidden risks of using earned value management only.
  • Make the case for implementing an integrated model of earned value management with critical chain project management that gives better early warnings to project management teams about any possible impact on the project completion date and budget.
