In our fourth article looking at the 14 point check we described how we at checked Finish to Start relationships, in this post we are going to take a look at Hard Constraints.
The DCMA criteria states that the total number of activities with a Hard Constraint should not be more than 5% of the total number of activities in the schedule.
Hard Constraint Check
To check this is Primavera P6 we used the following steps:
Step 1. Open Primavera P6 and the project you wish to analyse and add the Total Activities column. Make a note of the total number of activities.
Step 2. Create a new report using the Report Wizard by selecting Activities as it is activity data we require in the report. From Columns add the Primary Constraint field as we are looking to find out how many Hard Constraints are against the Project.
Step 3. Select Filter and create a filter to show only the Hard Constraints, create a report title and run the report. As we want the report in Excel select ASCII and ensure that the Text Qualifier is set to “.
Step 4. The report will open in Microsoft Excel, highlight the Activity ID’s and make a note of the count.
Step 5. Now simply divide the count of Hard Constraints by the Total Number of Activities to calculate the result.
If the percentage is 5% or lower than the criteria has been met, if higher than 5% then the schedule may require a review.
There are a further 13 checks prescribed by the DCMA which along with the Logic Check will be detailed out in further supporting documentation and video tutorials at http://www.myxacom.com where knowledge is no weight to carry.
