02 —

Assess

Evaluate feasibility, select a development approach and identify the key technical risks.

03 —

Develop

Optimise the assay chemistry or formulation towards an agreed prototype.

04 —

Verify & transfer

Evaluate analytical performance and document the workflow for the next development stage.
