Build & Test

There are two major goals that can be defined under the build and test umbrella, validating and verifying tests. Verification tests verify that the test module that we constructed was what we have actually designed. While validation will help the team to prove that the designed and built system is capable of completing the tasks desired by the customer.

The following link is to an Excel document listing and describing all of these tests. Tests

Assembly Instructions

Assembly Instructions

Assembly Instructions have been created as a part of the initial build/prototype process.

Any special care or other similar instruction that is necessary for the build/prototyping process is documented as a part of the testing procedures.

Test Plans & Test Results

Test information can be found at the link above. This document includes all of the testing procedures that are necessary for both verification and validation of our design.
