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.

Established Japanese TPS methodology preferred
OTRS10 is established within the Toyota Production System (TPS) tradition and follows its principles.
You value an extensive reference network
