Gate 3 - Product Analysis (Group 18)

Gate 3: Product Analysis

Purpose

In Gate 2, the RC Helicopter was disassembled to its basic components. In Gate 3, we can now produce a detailed analysis of each individual component. This gate contains all the information gathered from the examination of components at the subsystem level.

This gate consists of the Project Management: Coordination Review - Cause for Corrective Action and the Product Archaeology: Product Evaluation - Component Summary, Product Analysis, Solid Modeled Assembly, Engineering Analysis and Design Revisions

Project Management: Coordination Review

Cause for Corrective Action

Overall, our group members work well together. Our time spent in and out of class or labs has made us closer friends. Our main channel of communication though is through Facebook, mainly because we can quickly share information with one another or set up meetings. Besides Facebook, we also keep contact with each other through text messages and emails.

During the course of this gate however, all of our group members had several mid-term examinations in other subjects. This prevented us from meeting up according to plan, and thus we had to produce this gate in a short period of time.

We realize that we had overlooked this problem in our initial stages of planning, and therefore will take extra precaution in the future.

As for the future, we might potentially face another time shortage to complete Gate 4. However, we will be making more changes to our plan for lab times and meetings as the Thanksgiving break is coming up, leaving us little time to complete Gate 4.
