Product case study
From $19 / monthA schedule health audit that never sees your schedule.
Shaghool reads a Primavera P6 XER export and returns the DCMA 14-point schedule assessment with the offending activities named, one by one. A licence unlocks the browser tool; after the engine arrives, the schedule never leaves the machine it is opened on.
Every DCMA criterion is a countable property of the file: relationships without a predecessor, negative lags, hard constraints, float above a threshold. Planners still work through them by hand or buy a five-figure desktop licence. And the tools that do automate it are cloud services, which rules them out for anyone whose contract, employer, or jurisdiction forbids uploading a programme.
The XER parser is JavaScript running on the page. After a licence unlocks the engine, there is no upload endpoint — the schedule stays on the machine. Updates are automatic: every time you open the tool you get the current version.
A percentage tells a planner they failed; a list tells them what to fix. Every criterion expands into the exact activities or relationships that triggered it, exportable as CSV.
Criterion 12, the critical path test, needs the schedule to be recalculated with an injected delay. The tool cannot do that from a file, so it says so and explains how to run the test in Primavera rather than inventing a result.
Right-to-left brought real bugs: the comparison symbol in a threshold is mirrored by the bidi algorithm and silently inverts its meaning, and negative floats render back to front. Both are fixed, and dates can be shown in the Jalali calendar.
The first version computes 13 of the 14 criteria plus an out-of-sequence progress check, accepts an optional baseline file to sharpen the missed-activity and BEI measurements, handles multi-project exports, and produces per-criterion CSV, a summary CSV, and a printable report. Every result was verified against hand-calculated values on a reference schedule.
Product definition, schedule-domain logic, XER parsing, interface design, and verification.
A licence unlocks the browser tool, updates, and support. Qiyas, the two-file weekly comparer, is the next module and is now available. A written human review of one programme is also available if you want findings, not just a score.
