A schedule is a shared target , the fastest way to build a one-team mentality. When logic is visible, interdependencies are clear, and handoffs are transparent, teams align and execution gets smoother.
In real projects, everyone becomes a planner at times. People need to ask “what happens if…?”, test a change, explain a handoff, or run a quick planning session. But XER files often turn the schedule into something only specialists can read, so the schedule stops being a communication tool.
Actara is built around one mission: make planning accessible by making schedule logic transparent, easy to visualize, and easy to share so anyone on the project can review the logic, build understanding quickly, and do planning when it matters, right inside Excel.
XER View in Excel: open XER files and work in a familiar spreadsheet format
Navigate fast: predecessors, successors, resources, and codes in one place
Visualize the network: draw logic so dependencies are obvious
Identify the core network: focus on the chain that truly drives outcomes
Quick Risk: fast, lightweight risk signals to support decisions early
Compare two XERs: understand what changed between versions (logic/dates/structure) and why it matters
Planning sessions (workshops where everyone can see the logic)
Baseline reviews (logic checks, missing links, odd lags, float behavior)
Update reviews (what changed since last cut, what it impacts)
Schedule storytelling (explain the plan clearly to non-schedulers)
Quick risk conversations (early signals, not heavy simulations)
Shareable analysis (easy to send screenshots/exports to the team)
