Could you build this?
Partial Parsing XER/XML files and computing DCMA and earned-value metrics in the browser is buildable, but getting the checks and EVM math to match P6 results depends on project-controls expertise.
What it would actually take: A client-side app would parse the Primavera XER (tab-delimited text) and P6 XML formats, then run the DCMA 14-point checks and EVM calculations. The hard part is domain correctness: the checks have precise definitions, and matching P6 output needs test schedules and a planner to validate results. Real use also needs a planner to sign off on edge cases such as calendars, relationships and lag.
