Do I need a P6 licence to use it?

No. It reads the XER or P6 XML file that P6 exports, so anyone with the file can run the analysis.

Which files can I upload?

Primavera P6 XER and P6 XML exports, up to 400 MB. One project is analysed per file: if an XER holds several projects, the one with the most activities is used. Load further updates or a baseline alongside it for trend and delay analysis.

How are the DCMA checks counted?

As DCMA counts them: checks 1–10 measure incomplete activities, excluding level-of-effort and WBS summary rows, and relationships count when their successor is still open. Every threshold can be changed, and the counting basis can be switched to all activities for comparison with other tools.

Does it change my schedule?

No. Analysis never alters your file. Repair XER writes a new file, and only after you've reviewed every proposed change; the original is left as it was.

What if my file wasn't rescheduled before export?

The engine detects it: stored late dates that describe a stale plan, or a finish before the data date. It says so on the dashboard and recomputes the critical path from the logic instead of trusting the stored float.

Does the NEC4 check replace the Project Manager's review?

No. It assesses what a programme file can evidence against clauses 31.2, 31.3, 32.1 and 32.2. Narrative requirements, health and safety provisions and anything the Scope adds are listed to check by hand, with what to look for. Acceptance stays the Project Manager's decision.

Where is my programme stored?

The hosted service runs in the EU (Frankfurt) and every request travels over HTTPS. Enterprise customers can have a dedicated instance, or run it on their own servers.

Can I try it without signing up?

Yes. The live demo runs on a fictional 132 kV overhead line programme at its sixth update, with every module open. Uploading your own programme needs an account; the trial is free for 14 days.

What happens when the trial ends?

Your account moves to the free tier: one project, one upload a month and the DCMA summary. Nothing is deleted, and you can subscribe at any point to pick up where you left off.

Why it exists

Programme review is still done by hand. It shouldn't be.

A programme gets scrutinised by the client, the Project Manager and, if it goes wrong, a delay expert. This checks it the way they will, first.

Problem 1
Every period, the same checks rebuilt in Excel.
Open ends, leads, lags and hard constraints counted by hand, and counted differently each time.
Answer
Fourteen DCMA checks and 25 diagnostic checks on upload.
Each result opens to the activities behind it, with a CSV of the full list. The same rules every period.
Problem 2
Programmes rejected late.
A missing access date or no time risk allowance, found by the Project Manager after submission.
Answer
NEC4 clause 31 and 32 checks before you submit.
Each item passes, fails, or is marked to check by hand with what to look for, so nothing is silently passed.
Problem 3
A critical path nobody can defend.
Stored float from a file that wasn't rescheduled, so half the job reads critical.
Answer
A critical path recomputed from the logic.
Each activity on its own calendar, each lag on its predecessor's, and a warning when the stored dates are stale.

How it works

From export to assessment in three steps.

Measured on a 2,786-activity, 34 MB export: parsed in 4–6 seconds, the full report in under a second more.

Step 1
Export from P6
File → Export in P6, as XER or P6 XML. Schedule (F9) first so the dates and float are current.
How to export a clean XER →
Step 2
Upload
Drop the file in. Load earlier updates or a baseline alongside it to unlock trend and delay analysis.
Step 3
Read the assessment
Schedule Health, the dashboard, the Gantt and every other module, from the same upload. Export what you need.

Schedule Health

Fourteen checks, and the activities behind every one.

The 14 DCMA checks, counted the way DCMA counts them: checks 1–10 on incomplete work, and relationships only where the successor is still open. Each check shows its threshold, its result, a gauge against the limit and the activities behind it.

Every failed check opens to the activities that failed it, with a CSV of the full list.
Counted on incomplete work by default, so finished history doesn't flatter or punish the plan that's left.
Thresholds, the hard-constraint list and which checks count towards the score are all adjustable.

Forensic analysis

From what's wrong to what to change in P6.

A deeper pass, organised the way a forensic delay analyst reports: an executive scorecard with claims vulnerability, the critical path and float diagnostics, an anomaly register, root causes and a remediation plan down to P6's scheduling options.

Acumen-style metrics against stated thresholds, including logic density, hotspots and dangling logic.
With two updates, half-step attribution splits the finish movement into progress and revisions.
Liability is only ever a suggestion until a person assigns it, and the assignment is saved.

NEC4 programme checks

Know what the Project Manager will see before you submit.

The programme assessed against what NEC4 ECC clause 31.2 requires it to show, the grounds for non-acceptance in 31.3, and the revised-programme requirements of 32.1 and 32.2. Each item passes, fails, doesn't apply, or is marked to check by hand with what to look for.

Planned Completion against the Completion Date, and terminal float, in working days.
Judged on the programme as it stands now: work under way counts at its forecast finish.
What a programme file can't evidence is never silently passed. It's listed with what to check.
