PROPOSAL
● Explore user needs
● Define competitive advantages
● Perform research and pre-feasibility studies / activities
PHASE 1 Definition
● Design and development project initiative
● Clearly define product and customer needs
● Verify the accuracy of estimates made and identified in research and concept stage
(deliverables, timelines, budjet)
● Plan for development
PHASE 2 Feasibility & Optimization
● Design the product
● Show feasibility of manufacturing at acceptable cost
● Objective demonstration of product requirements to meet customer needs / requirements for intended use
● Design verification
PHASE 3 Verification
● Design freeze by establishing all crititcal parameters
(e.g. raw materials, composition assay compounds, design of assay execution protocol)
● Demonstrate manufacturing reproducibility at acceptable cost
(2 R&D lots benchmarked against design requirements)
● Fitness for intended use (accelerated stability studies for indicative shelf life data)
PHASE 4 Technical Transfer
● Transfer manufacturing documents and verification processes to manufacturing site
(after successful verification phase)
PHASE 5 Validation
● Validation of technical and clinical performance of 3 lots produced by manufacturing site
(ISO13485 and released by QA)
● Labeling validation lots as "Performance Evaluation Use Only"
● Grouping generated data of validation phase (can be used for filing assay at notified bodies)
PHASE 6 Transfer
● Transfer of all technical data and documentation, complete design history file (DHF)
and team evaluation to the customer
PHASE 7 Finalisation
● Obtain regulatory approvals according to launch plan
● Authorize the initial launch
● Introduce product to the market
● Monitor product performance in field
● Implement product support
● Initiate market surveillance
● Achieve market acceptance
● Close project and transfer design support to product manager
