Browse all six screenshots, use the thumbnails to choose a view, or enlarge an image to inspect the detail.

Milestone decision windows, source-data assurance and exposure, with an activity-level action table.
From exposure to a decision
Current and comparison dates stay visible as you explore. High quality JPEG and evidence CSV exports support the discussion outside the software.
Identify milestones needing a date or recovery decision. Open the decision window, data-assurance dials and exposure categories, then review the milestone action rows.
Select an activity and follow recorded dependencies into reachable milestones, cross-project interfaces and propagation depth. Compare dated current, previous and baseline bars in the same Gantt.
Explore which connected finishes fall inside a selected finish-shift window. Use scenario markers and switch current, previous, baseline and milestone tracks on or off.
Explore 15 complementary charts covering finish movement, constraints, milestones, comparison coverage, progress states and review signals. Drill into the selected chart and open tables when required.
Import multiple live XER files and select the previous-period and project-baseline comparisons. Clear project data when changing programmes. Stress Lab analyses connected exposure; it does not perform a P6 CPM reschedule or calculate completion probabilities.
