| Movement and control | Number and type of movements, motion range, control method, remote-control range under stated test conditions, and synchronization of movement with sound or lighting. | A continuous demonstration of the proposed configuration; control-system description; movement list; and written operating limits. | Demo shows a different model, movements are described vaguely, or control performance is promised without test conditions. | 20% |
| Build quality and materials | Frame construction, exterior skin or covering, joints, fasteners, cable routing, finish quality, and suitability for the intended indoor or outdoor environment. | Material and finish specifications, close-up photos, sample inspection, and a written statement of environmental limitations. | Materials are not identified, exposed wiring or uneven finishes appear in samples, or outdoor suitability is claimed without supporting details. | 15% |
| Safety and compliance documentation | Electrical and mechanical safety features, emergency stop or safe shutdown options where appropriate, and conformity requirements for the destination market and intended use. | Product-specific test reports, declarations, manuals, and component details. Check which requirements apply to the finished product in the target market. | Certificates cannot be matched to the quoted model, documentation names a different product, or the supplier treats a general certificate as proof of every requirement. | 15% |
| Reliability and maintenance | Expected operating schedule, maintenance intervals, access to serviceable parts, spare-part availability, and procedures for diagnosing common faults. | Maintenance schedule, parts list, troubleshooting guide, and test records for the quoted configuration, including the test method and duration. | No maintenance guidance, no identification of replaceable parts, or unsupported lifetime claims. | 15% |
| Customization and engineering | Ability to adapt dimensions, appearance, movement sequence, control interface, sound, and installation details; clarity about design ownership and revision limits. | A written scope, drawings or renderings, revision process, prototype approval stages, and a clear list of included and excluded changes. | Custom work is quoted without a defined specification, approval milestones, or agreement on tooling and design files. | 10% |
| Production and quality control | Production schedule, inspection stages, functional testing before shipment, packaging checks, and process for recording and resolving defects. | A project schedule, inspection checklist, sample test report, and agreement on pre-shipment inspection and acceptance criteria. | Dates are given without milestones, inspection is not documented, or acceptance criteria are left undefined. | 10% |
| Warranty and after-sales support | Warranty period and exclusions, response process, remote troubleshooting, replacement-part terms, and responsibility for shipping costs. | Written warranty terms, support contact process, parts pricing or policy, and a clear description of how claims are handled. | Only verbal assurances, unclear exclusions, or no defined process for parts and repair support. | 10% |
| Total cost and delivery terms | Itemized equipment, customization, tooling, packaging, shipping, installation, spare parts, and payment terms; compare quotations on the same delivery basis. | A dated, itemized quotation; stated trade and delivery terms; shipment dimensions and weight; and a schedule showing key dependencies. | A single unitemized price, unclear exclusions, or delivery estimates that omit approval and shipping stages. | 5% |
