1Design and development planning: 





Planning of Design and development activity consists of:-


•Planning







•Review of the plan at identified stages




•Assign responsibility and authorization for implementation


•Interface – Identifying organizational interface with different groups and the purchasers if necessary, Maintain a record (EAPL / DD/ F – 01) of the same.•Planning output is updated as the design progress.












2Design and development Inputs: 





It takes into account:-





•Functional and performance requirements



•Applicable statutory and regulatory requirements



•Information derived from previous similar design



•Other requirements essential for design and development.


•Design and development inputs are reviewed for adequacy, any conflicting or ambiguous requirements are resolved.•Records of design and development inputs are maintained as per EAPL / DD / F – 02.









3          Design and development Outputs:





It is ensured that design and development outputs: - 


•Meets input requirements





•Provide appropriate information for purchasing and production

•Refers product acceptance criteria




•Characteristics for safe and proper use are identified


•Design and development output is approved before release

•Design and development output is recorded as per EAPL / DD / F – 03.










4          Design and development review: 





Design and development review is carried out at planned intervals to ensure that: -•Ability and result of design and development meets the requirements of product•Problems are identified and necessary actions are taken before finalizing design•Design and development review is carried out during planning of each design and development activity. Participants include representative of all function concerned as well as specialist if required. Records of design and development reviews are maintained.



















5         Design and development Verification: 




Design and development verification is carried out to ensure that design and development outputs met design and development input requirements specified application and intended use. The method is decided at the stage of the design and development planning. It may consist of comparison with a proven design, comparing out alternative calculations, carrying out demonstration or any other method agreed  with customer or marketing department. Results of verification are maintained as per EAPL / DD / F - 04









6Design and development validation :




Users need / intended use are ensured by design and development validation. Prototype testing, Lab Testing,   Field trials are  some of the method used form design and development validation. Results of validation are recorded in EAPL / DD / F - 05



















7Design and development changes :





If any changes occur to the existing design, it is identified and records are maintained. Such changes are reviewed,  verified and revalidated and approved prior to release for product. Results of design and development changes shall be recorded in ( EAPL/ DD / F – 06)
