Risk Management

Protecting the value of a project involves dealing with the uncertainty that will be associated with its delivery.  
We have adopted systematic Risk Management to maximize opportunities and values and minimize threats. Risk management as improved every aspect of our business and effectively saved time and money for all stakeholders.
Risk Management uses various set of statistical and analytic tools (modeling software) to produce value enhancement in our jobs.
For our projects, even the fast-track ones, there are often long and complicated processes in the supply chain. No matter how good a project schedule is or how well resources perform in the execution of tasks in that schedule, if critical dependencies associated with the project are not included in the description of the effort, they represent considerable risk to delivering project value.

Among most important factors, the following list remarkably applies to  most projects:
  • Design information holds and shortages
  • Late issuance of design documents
  • Late vendor data
  • Changes
  • Reworks
  • Delayed procurement
  • Contractual arguments

Risk Management has helped us minimize the impact of theses factors. It has reduced and minimized the flow of uncertainty in decisions.
As an essential precursor to implementing Risk Management we have clearly defined the goals of our projects, considering constraints and assumptions.
We identify risks to the main objectives of projects by incorporating previous projects Lessons Learned which are systematically provided and issued through Rahan Sazeh Quality Management System (RSQMS).

Risk Management is the continuing process of planning, identifying, quantifying, responding to and controlling risks to maximize the potential for the success of a project or an activity. It is a coherent and comprehensive approach to project management that encompasses and effects other processes and practices associated with project management as well.
