Name the points of attention.
- Latency
- Continuous firmware optimisation and repeated field measurements through the Abyss programme.
- Impact resistance
- Strips and mounts tested in real conditions by Abyss testers before production.
- Crosstalk
- A trigger can react to a neighbouring drum: a known concern, closely monitored in the field through the Abyss programme.
- Electronic component availability
- Choosing common components and building a buffer stock before production.
- Mobile stability
- Testing across a wide range of devices and priority fixes reported by testers.
- Compliance
- Compliance prepared with the help of specialised providers before shipping.
- Single supplier
- Identifying alternative suppliers for critical parts.
- Solo creator workload
- A deliberately tight scope and occasional use of targeted providers.
