Understand Project Logic in Seconds with Aurora‑Viewer

Visualize Project Relationships Instantly with Aurora-Viewer

Large Primavera P6 XER files are notoriously difficult to untangle. Projects often include tens of thousands of activities, each linked by complex webs of dependencies. Manually tracing those relationships can take hours—sometimes days—of scrolling, filtering, and cross-referencing just to answer a single question: Why is this task delayed?

Aurora-Viewer changes that. Built by Stottler Henke, the system provides instant clarity into massive project schedules, revealing the logic that drives timelines in just seconds.

Instantly See the Bigger Picture

Instead of wading through dense tables or complicated Gantt charts, Aurora-Viewer gives users an intuitive, visual interface that highlights the relationships that matter most. You can quickly see how one activity affects another, trace driving paths, and identify potential bottlenecks—all without the need for complex setup or data preparation.

The result? You spend less time deciphering your schedule and more time managing it. Aurora-Viewer lets planners, schedulers, and stakeholders instantly understand project logic—no matter how large or intricate the file.

From Confusion to Clarity

Traditional scheduling tools can make large XER files feel like black boxes. When you need to understand why a milestone has shifted, you often end up digging through dozens of predecessor and successor chains. Aurora-Viewer removes that pain. With a few clicks, users can trace any activity’s logic chain and immediately see which dependencies are driving—or constraining—progress.

This capability is especially valuable for teams working on major programs such as construction, aerospace, or energy projects, where multiple contractors and schedules converge. Aurora-Viewer transforms complexity into clarity, making logic tracing a matter of seconds instead of hours.

Designed for Speed and Insight

Aurora-Viewer’s performance is optimized for large data sets, allowing users to load and explore massive XER files with minimal lag. The software’s intelligent visualization engine focuses on relationships rather than raw data, displaying critical paths, float chains, and interdependencies in an easily navigable format. This speed empowers users to perform rapid “what-if” investigations, communicate findings clearly, and maintain schedule integrity across teams and projects.

Empowering Smarter Decisions

When project teams can understand logic instantly, they can make better, faster decisions. Aurora-Viewer enables proactive risk management by helping users spot fragile sequences, redundant links, or unanticipated constraints before they become costly issues. Whether you’re auditing a schedule, reviewing a contractor’s submission, or validating your own logic, Aurora-Viewer gives you the visibility to act decisively—without the hours of manual analysis.
