Logic League by Ron Winter Consulting LLC.

Logic League™

Logic League™ is your extended data base for CPM relationships. With Logic League and P3, P3e, or P3e/c, you can add notes, sort by any predecessor or successor factor, filter out unnecessary relationships, maintain any number of scenarios, and instantly update your schedule. Quickly reverse preferential logic, accelerate schedules using a relative degree of ‘Hard’ and ‘Soft’ settings with cost or disruption as a factor. Automatically document all changes made. Safety and accountability are built-in.
Logic League reads your Primavera Schedule and builds its own logical database that includes everything in Primavera and more. You can view and manipulate your relationships like you do with activities in Primavera. Save the extra information in a separate database and reuse it the next time you use Logic League.
Now you can keep ‘unused’ logic relationships and apply them when you want. Swap out entire logical sections of your schedule for another set with just one function. Special updating functions keep your Logic league database up-to-date with your Primavera schedule.
Besides logical information, other data available to you includes,
Any two activity codes,
Early and planned dates,
Resource information,
Total and free float.
With the above information, you can readily analyze the nature of each relationship. Here is a screen shot of a typical Logic League display.

Each horizontal line represents a single logical relationship between two activities. Predecessor information is displayed on the left in blue, followed by the relationship in black and then the successor information in green. The user-supplied information to the right of the splitter bar (not shown) includes hard & soft indicators, relative weights, priority values, relationship code, and notes.
You sort the database by clicking on the column headers. The current sort column is highlighted in dark blue. A very light blue is used to automatically color the entire line depending upon the sort column entry. Whenever the value changes, the line goes from light blue to white and back to light blue when that value changes again. We call this a Horizontal Sort Break.
The information in the grey at the bottom automatically changes when you change the currently highlighted line. This information is an expansion of the necessarily condensed information in the current line. It lists the current predecessor’s activity description and the successor’s activity description. Above this (in light blue) is a complete expansion of the sort column description and the current value in that line. In the example above, we are sorting on, “Pred Area” and the value, “3” displayed is defined in Primavera as, “E3, Eastbound Aux Lane.”
The white box in the lower right corner is the note for the currently selected relationship. You can type and edit this field as you wish; using wrap-around text or multi-line formatting as desired.
When you are done, you can print the database or even save it to an Excel spreadsheet. Backup and restore your Logic League database easily.
