Introduction

Out-of-sequence activities in Primavera P6 can create significant problems for project managers, including delayed project completion, inaccurate forecasting, and incorrect resource allocation. This step-by-step guide will help you resolve out-of-sequence activities in Primavera P6 quickly and easily.

To fix the out of sequence activities, we will use the P6 out of sequence tool. We will export the activity relationships to an Excel file and modify it to include additional columns such as predecessor and successor activity status. To do this, we will go to the resource tab in Primavera P6 and modify the columns as needed. We will then export the file to our desktop using the P6 out of sequence tool that can be downloaded from the link in the video description.

Once the file has been exported to our desktop, we will open it and select all the activities that we want to fix. We will copy these activities and paste them into the P6 out of sequence tool. The tool will identify the out of sequence activities and provide options to fix them. The first method is to remove the relevant out of sequence activities.

However, we can also use other methods to fix the out of sequence activities, such as adding new activities or changing the logic of the schedule. It’s essential to analyze the impact of these changes on the schedule and adjust accordingly.
