Primavera Risk Analysis Tips & Tricks 01-13

Objectives:

To demonstrate one of the correct methods of importing or converting Primavera project files to Oracle Primavera Risk Analysis (OPRA). To teach the new Risk Analyst how to align the OPRA schedule to the original P6 schedule and ensure an accurate Schedule Quantitative Risk Assessment. To save time and optimize effort.

ABSTRACT

Many risk professionals have experienced much difficulties using PertMaster (now known as OPRA) in processing their sample deterministic schedule for quantification and analysis.

The persistent issues encountered, especially by new would be risk analyst is the discrepancy of the risk plan file and the original multi-calendar Primavera schedule after import. If the flawed translation is not properly addressed, reference and original deterministic dates of affected activities will stay misaligned, producing erroneous results.

This short write up will attempt to present the secret key to the proper use of the tool and prevent loss of data quality, hence, an accurate risk assessment!
