Introduction

The Synthesis Leaders have been providing consumer solutions since early 2012. Our COMPANY PROFILE takes new technology and creates innovative solutions for consumer and customer service applications. Our VISION is to bring proven technology solutions to the marketplace for consumer needs.

Need Statement

Grocery shopping can be an intimidating ordeal. Customers are bombarded with long aisles with multiple signs, constantly changing sections, and distracting food samples which prevent them from reaching their final destination, the checkout, in the shortest time possible.

experience by helping shoppers to navigate the grocery store and the many distractions. The system will map out the shortest route through the store and back to the checkout register allowing the customer to collect all items on their shopping list in the most expedient way possible .

A psuedolite based system is the optimal solution

All other criteria being equal, a psuedolite based system Is more accessible to store customers

Does not require dependency on a third party, e.g. cell carriers

A psuedolite based system will cost more however the provided capability will give a competitive edge over competitors

Trade Study 1 Conclusions

Goal Determine optimal size of the touch screen display

Screen size is weighted more than cost of the screen

Criteria Screen Size Measurement from bottom left corner to the top right corner of the display

Cost Cost of the touch screen display

Taking weighting factors in consideration

The optimal size for the touch screen display is between 6 and 6.5 inches at a cost of $45

Sensitivity Analysis

Increasing/ decreasing the cost weighting factor by 50% has no effect on the results

Increasing/ decreasing the screen size weighting factor by 33% has no effect on the results

Dynamic and phased testing

o In accordance with test cases and procedures

o Defects and discrepancies will be tracked and reported

Environmental Stress Test performed on a prototype

o Prototype will be as close to production hardware as necessary

o Heavily involves display unit, relay station, and database servers

Qualification Testing done on first article, focuses on Software requirements

o Verification for formal sell-off occurs at the system level

o Sub-system level test cases will trace up to the System Specification

Factory Acceptance Test, individualized hardware checkouts

o Done on each hardware deployment to ensure operational functionality

Verification Overview

Several Prototypes designed to validate system concept

Visual Prototype Mock system (nonfunctional) developed to show customer the approximate size and weight of system components

User Experience Prototype Prototype of the GPS receiver developed for human factors testing

Validated touch screen size trade study results that 6-6.5 inches was the optimal size for the touch screen
