 Now since the group is in a steady groove of meetings, everything seems to be coming together which has, in turn, made these assignments less stressful. This gate, however, coincided with a high number of exams for each group member. With that as an obstacle, some group members had an issue for getting their work completed at an acceptable time. Though the group is meeting and discussing what needs to get done each week, some still have a problem of actually completing and handing in quality work for his section. To fix this we, as a group, will need to push harder for deadlines to be met, and for it to be made clear that we are all affected by each members individual performance.
-After this gate is completed the group goes home for Thanksgiving break, which means that there won't be a meeting next week. To stay on track for gate 4, the group has created Facebook group page where we are able to post pictures, documents and keep in contact with each other and continue our work without missing a beat.

-This gate compared to gate 2 required less hands-on work and more analysis work. Gate 2 helped the group to more fully understand how the product works, this has made the work needed to be done for this gate a lot easier. However, the group's main issue for the last gate was time management.

-Prior to gate 2, the group would send all of the work to one group member. That member would then upload and format everything on the wiki page by himself. Midway through the second gate the group realized that uploading to the wiki page was very time consuming and just too much work for only one person to complete. So the decision was made to have another person learn the wiki language and have them simultaneously put up the group work for the gates. The work was more easily divided, which aided in completing this assignment.

-Now since the group is in a steady groove of meetings, everything seems to be coming together which has, in turn, made these assignments less stressful. It was especially convenient for this gate because of the high number of exams the group members had the week before this gate was due. After this gate is completed the group goes home for Thanksgiving break, which means that there won't be a meeting next week. To stay on track for gate 4, the group has created both a Google and Facebook group page where we are able to post pictures, documents and keep in contact with each other and continue our work.

It also isn't shaped to fit in the user’s hand as well as it should be. More contours would probably make this handle more comfortable for the user and more easily usable for longer periods of time.  Also by counterbalancing the product, it wouldn't feel as awkward to hold and again would be easier to use for longer periods of time. These ergonomic changes would be a societal factor design change to better improve the usage by the user.

This casing could be upgraded in design by changing the material or type of plastic used. The current material could be changed to a plastic or a synthetic that provides the same strength required for drops or bumps but uses less material. This design change would be an Environmental factor design change to reduce the amount of waste or thinking about the end life of the plastic and the leaf blower. This could be less cost efficient and would have to be considered as what would be a better trade off in the design goals.
