ProjectEngine executive dashboard in Excel
Not a template. A real scheduling engine.
Not a disconnected dashboard. One calculated planning model.
Not another mandatory application. It runs inside Excel.
LIVE SIMULATION

Move one activity. See the whole schedule react.

Drag a task, propagate the dependency network, recalculate the Critical Path and float, then return safely to the last calculated plan with Reset.

SCHEDULING, NOT DECORATION

What ProjectEngine calculates

The Gantt, analytics, Dashboard and S-Curve consume the same calculated planning data.

↗

Dependency-driven scheduling

FS, SS and FF relationships, positive or negative lags, multiple predecessors, calendars, milestones, constraints and automatic propagation.

◎

Critical Path and float

Critical Path, Longest Path, Total Float, Free Float, Driving Logic, variance, deadlines and multi-project criticality.

⟳

Controlled simulation

Non-destructive TEST, complete SCENARIO alternatives, live Drag & Drop analytics, safe Reset and controlled LOCK.

!

Planning diagnostics

Structured INFO, WARNING and STOP messages for missing predecessors, cycles, invalid constraints and inconsistent planning inputs.

▥

Interactive Gantt

Day, Week and Month scales, summaries, milestones, LOE tasks, dependencies, constraints, progress and path overlays.

∿

Project controls reporting

Executive Dashboard, Hot Spots, Baseline/Actual/Forecast/Calculated S-Curves and time-phased workload distribution.

A CONTROLLED WORKFLOW

From WBS inputs to a validated schedule

ProjectEngine separates user inputs, calculation, analytics, diagnostics, simulation and publication so the workbook remains understandable and testable.

  1. 1
    Build the WBS

    Enter hierarchy, dates, durations, progress, calendars and dependencies.

  2. 2
    Run Planning Update

    Calculate dates, rollups, constraints, paths, floats and diagnostics.

  3. 3
    Review the result

    Use the Gantt, analytics, Dashboard and S-Curve.

  4. 4
    Test alternatives

    Simulate focused changes or complete scenarios before committing them.

  5. 5
    Lock or Reset

    Apply validated results or return safely to the calculated plan.
