Search statements and sourcesState needs before solutions
Describe who must understand what information and where. Record use and site conditions before selecting a technology. Explicitly mark requirements, preferences and open assumptions. If on-site sampling is needed, set content, positions and evaluation method so suppliers price the same scope.
Request comparable evidence
Every key requirement needs a response with a model, document or test. Ask suppliers to mark deviations in a separate column. A spec sheet without installation context cannot approve the use. Request a complete bill of materials, licenses, mounting, commissioning and service. Compare total costs using the same term and site assumptions.
Define acceptance and handover
Check real content, switching on and off, language switching, offline playback and relevant failure cases. Assign an expected result and owner to each test. Handover includes asset register, approved configuration, service instructions and training. Record defects with a deadline and recheck before approving a broad rollout.
PLANNING EXAMPLE
Planning steps and acceptance checks
Three suppliers receive the same needs matrix. For each mandatory requirement they name a model, document or demonstration and mark deviations. The project team compares complete scope and records open questions. A pilot passes agreed tests before rollout. A better price or attractive demo does not compensate for unresolved mounting approval. The brief, supplier response and acceptance record should reference the same requirements so later changes remain traceable.
| Aspect | What to check |
|---|---|
| Normalize supplier responses | Each proposal covers the same scope or marked deviations |
| Check pilot against mandatory requirements | Every requirement has evidence or an open defect |
| Review handover | Asset register, instructions and owners are documented |
What to bring to the project discussion
| Aspect | What to check |
|---|---|
| Requirement | Mandatory, preferred or open |
| Supplier response | Evidence and deviation |
| Cost | Hardware, software, installation, service |
| Acceptance | Test, expected result, owner |
Three concrete next steps
- Create a project brief and enrich it internally.
- Give every supplier the same evidence matrix.
- Agree on pilot and handover documents in advance.
Limit of this recommendation
Generated requirements remain suggestions. Site assessment, specialist design and internal approval determine what is mandatory.
Sources & context
Planning advice: check the model-specific documents for your use. Procurement documents
Request documents for the exact model and assess the planned installation before acceptance. Prepare a correction
