Is OTRS10 the same as OTRS (the ticketing system)?

No. OTRS10 is a time study and work measurement software by Broadleaf Co., Ltd. (Japan), distributed internationally by Shinka Management. It is completely unrelated to the OTRS open-source ticketing system.

Can Yamazo Studio replace OTRS10?

For most time study and work analysis use cases, yes. Yamazo Studio offers comparable or superior features in video analysis, yamazumi charts and standard work, and adds capabilities OTRS10 lacks (SMED tracking, WERA ergonomics, LAN multi-user sync via Opsida Airlock). OTRS10's notable edge is its AI single-cycle element detection — but that runs in Broadleaf's cloud, whereas Yamazo's AI work analysis (WorkSense, pilot) runs on-device and fully offline.

Does Yamazo Studio work with Kaizen Institute methodology?

Yes. Yamazo Studio supports standard kaizen workshop workflows — video recording, waste identification (VA/NVA/MUDA), yamazumi chart generation, and before/after comparison. The methodology is universal; you don't need a specific software brand to practice kaizen.

OTRS10 uses an annual subscription model. Yamazo Studio is offered as either an annual license or a perpetual license (one-time purchase, lifetime use of the version bought). Over 2-3 years, the perpetual option typically costs less than the cumulative OTRS10 subscription fees while providing lifetime use of the purchased version.

When to Choose

Choose Yamazo Studio when...

You need 100% offline operation

If your facility requires air-gapped operation or strict data sovereignty, Yamazo Studio runs entirely offline after activation. No license server, no cloud connection, no data transmission.

You want an all-in-one lean analysis platform

Yamazo Studio combines time study, yamazumi charts, SMED tracking, WERA ergonomics, and line balancing in one tool — replacing multiple separate software licenses.

You prefer one-time ownership over subscription

Yamazo Studio's perpetual option is a one-time purchase with lifetime use of the version bought — no annual renewal fees, no per-user costs, no surprise price increases. An annual license is also available if you prefer a lower upfront cost.

You need LAN-based multi-user collaboration

Opsida Airlock enables multiple engineers to work on the same project over the local network — a capability no competitor currently offers.

Consider the alternative when...

You need Toyota-validated methodology

OTRS10 was developed with Toyota Motor Corporation and follows Toyota Production System principles. If your organization requires this specific validation, OTRS10 has the heritage.

You value an extensive reference network

With 6,000+ installations and clients like Toyota Boshoku, Honda, and Sony, OTRS10 has a proven track record across major manufacturers. Yamazo Studio is newer to the market.

You need Kaizen Institute integration

If your organization works with Kaizen Institute consultants, OTRS10 is their official time study tool (KAIZEN Time Study powered by OTRS), available through their 60-country network.
