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

Schedule calculations remain the foundation for Gantt, analytics, Dashboard and S-Curve; Finance adds a separate, explicitly refreshed cost-reporting domain.

↗

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.

€

Financial project controls

Activity budgets, actual expenses, ETC/EAC cost forecasts, monthly financial charts and dated expense journals.

▦

Multi-project finance

Manage independent or shared financial records across projects and consolidate costs without double-counting.

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
Build the WBS
Enter hierarchy, dates, durations, progress, calendars and dependencies.
2
Run Planning Update
Calculate dates, rollups, constraints, paths, floats and diagnostics.
3
Review the result
Use the Gantt, analytics, Dashboard and S-Curve.
4
Test alternatives
Simulate focused changes or complete scenarios before committing them.
5
Lock or Reset
Apply validated results or return safely to the calculated plan.

ONE PLANNING MODEL

Analytics and reporting stay aligned

ProjectEngine planning analytics in Excel — Critical Path, Longest Path, float, variance and Driving Logic.

ProjectEngine S-Curve analysis in Excel — Baseline, Actual, Forecast and Calculated progress.

LATEST PROJECTENGINE RELEASE

What's new in ProjectEngine?

ProjectEngine v1.5.1 focuses on trustworthy results: more accurate scheduling and float, clearer Dashboard alerts, S-Curve fractional progress, Gantt dependency recovery, and safer project migration. Financial project controls and multi-project reporting introduced in v1.5 remain available.
