Schedule Validator was built by people who have spent careers in the field, defending schedules in front of owners, untangling forensic delay analyses, and watching the same problems repeat on projects around the world. We built this tool because we needed it ourselves.

"Rid the world of poor quality schedules."
That is not a marketing line. It is the reason every feature in Schedule Validator exists.
Project schedules are the most important planning tool on any major project. When they fail, through missing logic, broken dependencies, or a critical path that drives nothing, teams make bad decisions, owners lose trust, delays compound, and disputes follow.Schedule Validator exists to make schedule quality objective, measurable, and improvable. For every project team, in every industry, on every continent.

Schedule Validator was founded by Sylo Management, LLC, a team of project controls professionals who had spent years watching the same failures repeat on projects across every sector and every continent.
Schedules submitted on time but riddled with missing logic. Critical paths that weren't driving anything. Forensic delay analyses that fell apart the moment someone looked closely at the underlying schedule data.
The answer was always the same thing: a consistent, objective standard for schedule quality. Not a checklist buried in a contract specification. Not a manual review that consumed days of a scheduler's time. A score, one number that anyone on the project team could read, understand, and act on.
We built that tool. We have since analyzed over 250,000 schedules across 92 countries, representing nearly $1 trillion in project value. And we are still run by the practitioners who started it.
The SV Score reflects honest evaluation, not a result engineered to look good. We say what we mean, and the platform does what we say it does.
Schedule quality analysis is only useful if it is correct. Every attribute we evaluate is grounded in industry-recognized standards and validated by practitioners who work in the field.
Project controls evolve, and so do we. Our scoring criteria are reviewed and updated annually to stay aligned with DCMA, AACE, and the way modern schedules are actually built.
When a scheduler uploads a schedule at 10 pm the night before a 7 am owner submittal, the platform needs to work. We build and maintain Schedule Validator for exactly that moment.
Schedule Validator is built around how schedulers actually work, not how someone imagined they might. User feedback shapes the product roadmap directly.
We hold ourselves to the same standard we ask of project teams. Our methodology is transparent, our criteria are published, and our team is reachable.
Whether you're evaluating the platform for your organisation, have a support question, or want to talk enterprise — we're reachable.
