Marketing Assignment Help With Trade Study Analysis

Purpose & Objective

Need to identify the best type of display monitor for the ECU device. The display shows data on:

- Heart Rate of crew

- Messages Received from Command Center

- GPS position of downed crew

- GPS satellite signal strength

Cost was considered separately so as to enable cost/effectiveness as a separate evaluation factor.

Identify Alternatives

- Liquid Crystal Display

- Cathode Ray Tube Display

- Display that Translates Text to Speech

Formulate Selection Criteria

-To maximize ELU portability, determine smallest display size but information can still be easily read/obtained

- Power consumption of the display

- Can withstand hot temperatures or submersion in water

- Reliability of the display to accurately provide data

Scoring

Scale: 1 – 5

Maximum Weight: 5 (Most critical factor)

Minimum Weight: 1 (Least critical factor)

Purpose & Objective

- Identify the type of wireless monitoring device that will supply optimal data to the EKG Monitor located on the ELU.

Cost was considered separately so as to enable cost/effectiveness as a separate evaluation factor.

Identify Alternatives

- Chest Strap– monitors pulse directly from the heart

- Wrist Bands– two bands monitor pulse directly from veins located at each wrist

- Head Band – monitors pulse directly from temples

Formulate Selection Criteria

- Signal strength of the wireless transmitter located on the device (does location make signal weaker?)

- Comfort for crew member (is it in the way of other gear? Hinder job responsibilities?)

- Accuracy of the device given its location (where is the best pulse received?)

- How Secure is the device given its location (moves around a lot? Protected from other objects?)
