Platform / Ground truth models

Ground truth you can defend.

Our AI never guesses. Every answer runs through industry-standard project controls models, built by scientists, continuously tested for accuracy and open for anyone to check.

A glass box, not a black box

Four reasons your experts can stand behind every number.

Industry-standard methods

Monte Carlo simulation, the 14 DCMA checks, earned value and critical path analysis, continuously tested for accuracy. Recognized methods, not mystery math.

Your standards, built in

Set your thresholds, checks and critical path rules once, and every project is measured against them. If anyone changes the standard, you’ll see exactly what changed.

Open to inspection

See the activities behind every number, the raw correlations behind every driver, and the dates behind every delay call.

Your schedule, untouched

Analysis never edits your source schedule. Even optimized schedules come back as a brand new file.

The models

See how every model works.

Pick a model to see the method behind it and what your team can check for itself.

DCMA and proprietary checks

Integrity

How it works

Runs every check across every WBS and activity, scoring each green, amber or red against your thresholds.

Check it yourself

Go from the overall score to the exact activities failing any check, and export them in one click.

Why it holds up

Every project is compared with your workspace default, so you know when anyone changes the standard.

Built for real schedules

It plays by the same rules as your schedule.

Every calendar

Each activity is scheduled on its own business calendar, including floats and relationship lags.

Every constraint

Handled consistently with major scheduling platforms, including Oracle Primavera P6.

Lags and leads

Positive, zero or negative, applied on the right calendar for each relationship.

Your critical path, your way

Float-based, or the longest path exactly as it comes out of your P6 file.

Messy logic, handled

Cycles are detected and ordered so analysis still runs, and flagged so you can fix them.

Red flags surfaced

Changed actual dates, progress going backwards and work marked done in the future.

Built by researchers, not just engineers

We’ve spent years studying why big projects slip.

Our team’s published research papers form the foundation of our technology. Eight peer-reviewed papers on how delay and risk move through project networks. Fitting, for a company called Nodes & Links.

Neglecting complex network structures underestimates delays in a large-capital project

KEY FINDING

The standard float-based view of how delay spreads systematically underestimates the risk, because it ignores how the activity network is actually wired.

THE DATA

68,546 activities and 84,934 dependencies from a $1.86B infrastructure project

FAQ

Questions, answered.

How our ground truth models keep every answer defensible.

Talk to our team

A proven project controls workflow, such as DCMA checks, QSRA or Delay Navigator, that the AI must use to answer. It’s what makes every answer traceable and defensible.

Every answer runs through the models and comes with its sources and evidence trail. You can open any answer in Platform Mode and check the math yourself.

Yes. Set your thresholds, checks and critical path rules once, and every project is measured against them. If anyone changes the standard, you’ll see what changed.

No. Analysis never edits your source schedule. Even Schedule Optimizer returns its results as a brand new XER file.

Our team of researchers and engineers, led by co-founder and CTO Dr. Christos Ellinas. The team has published peer-reviewed research on how delay spreads through project networks.
