Decision ledger · Questions before conclusions

Compare the questions each direction needs to answer.

Platform selection starts with the formulation, product format, use context, maintenance expectations and evidence plan. This page frames comparison questions; it does not name a universal best mechanism.

A brief-led comparison, not a ranking.

Each row identifies what the brief must define and what the programme must validate before selection.

Direction	Define in the brief	Validate in the programme
Smart Particle Waterless Diffusion	Formulation, product format and evidence plan.	Validate formulation range, disclosure scope and model-specific performance under the agreed evidence plan.
Pump Nebulizing Diffusion	Reservoir architecture, controls, installation and maintenance context.	Set model-specific output, coverage, compatibility and noise targets, then validate them under agreed conditions.
Micro-Nozzle Waterless Diffusion	Architecture, intended use and validation plan.	Confirm service, compatibility and reliability for the selected configuration before release.
Ultrasonic Water-Based Diffusion	Water handling, placement, interaction and service needs.	Validate output, coverage and operating conditions for the selected model and configuration.
Separate solution · Fragrance Diffusion Humidifier	Integrated product intent, interaction, water and evidence zones.	Treat model identity, capacity, output, coverage and runtime as separate evidence questions for the selected configuration.

Questions to carry into validation.

A direction becomes useful only when the conditions and acceptance plan are explicit.

Which formulation and configuration will be evaluated?
Which use, installation and maintenance conditions matter?
Which observations or measurements support the decision?
Which limitations or unresolved questions must remain visible?

Turn the questions into a project brief.

ODM Development shows how the brief and validation questions pass through client approval gates.
