Results Evaluation

We are promising:

Objectives to be metConstraints to be satisfiedStandards to comply withPatents not to infringeSpecification

Life Long Learning

We know that getting this product into production was no small task. However, we have some understanding of the steps we need to take in order to make this happen. We need to find buyers that are going to use and make this product continue to sell in the future. The team will continue to read magazine to stay updated on what is being done with technology so that we can improve our product and ourselves. Finally, we continue to study and practice the skills we learn to become better engineers.

Conclusion

The idea for this project came from our mentor Professor Ismail Guvenc.During the interview with our mentor, we learned the different concepts that this project would be composed of and the basic structure of how it was going to work.

Conclusion

The main activity involved in completing this proposal was by far research. We needed to do an incredible amount of research to write this proposal, which included looking into intellectual properties, global and ethical considerations, marketability of our product, and how the product and its different sections function. In addition, we complied with the standards that apply to this project and were sure not to infringe on any existing patents.This project has made us see how technology can benefit society and how there it is always expanding and will continue to do so.

In conclusion, we were able to see our clients needs come to fruition using our aptitude and skills.
