Job Analysis

I believe our product did meet design specifications. It started at a very cold temperature, and it only gained 8 degrees over the course of 4 hours. The total cost of our project was $7.35, which was a little more than what we anticipated. Our team worked well together, but our work was pretty average, it definitely could have been much better. The biggest challenge for our company was coming up with ideas, but we were able to overcome that obstacle. Something that could have made our job easier, would have been a wider variety of materials.
