All of us have our own view of what MUST be the proper New Product Development phases. I believe those are:

1. Ideation: Come-up with an idea you think it could be a market winner.

2. Patenting: Evaluate the merit of getting Intellectual Property (IP) protection for your new product idea.

3. Design: Develop non or partially functioning models of your new product idea and start soliciting user feedback.

4. Feasibility Proof: Perform various technical/business studies to determine IF your new product idea is feasible.

5. Development: Develop a product/process to yield a number of fully functioning new product prototypes as if each of them were to be used by the final user/customer.

6. Controlled Field Use Trial: Let potential users use the new product as IF it were purchased by them and generate feedback based on a previously approved protocol.

7. Design-Verification/Validation: Fine-tune new product design/development and complete design verification/validation studies to confirm the new product meets User Requirement Specifications (URSs) per its respective Labeling Claims.

8. Regulatory Filing (if required): Prepare any required documentation and submit it to appropriate Regulatory Authorities for securing their approval to market it.

9. Full Field Use Trial: Repeat above phase 6 but using a comprehensive pool of potential users/customers.

10. Scaling-up: Scale-up your process so your new product could be manufactured in high quality/low cost conditions.

11. Technology-Transfer: Develop documents' list for new product's production in high volume.

12. Process Validation: Validate your process so it produces final product consistently meeting specifications.

13. Manufacturing: Start manufacture and ship product to market.

14. Launch: Launch product and monitor its acceptance by the user.

15. Line Maintenance/ Improvement: Compile, analyze user feedback and continuously improve product.
