Table of Contents

Your website should document your journey through MSD, so include work-in-progress as well as latest results. Use pdf's for display whenever possible so that information is easily viewable without the need to download files and open applications. (Your EDGE file repository should still contain original files).

Sample categories are listed below, but feel free to change or add nodes to better correspond to your project and your Guide's expectations.

Project Summary

Bow and arrow hunting is a popular outdoor activity. Current arrows may fatally injure the wildlife being hunted, though the animal may not drop in place. Animals that are fatally injured can travel a substantial distance before their death.

To help locate the wildlife and avoid wasteful killing, a reusable wildlife tracking device will be deployed with the shot arrow and detach upon impact. This device will track the movements of the injured animal and relay that information to a user pocket monitor allowing a hunter to recover the wildlife as well as the tracking device.

Customer Requirements (Needs)

Customer Need Importance Description
CR1 9 The device locates the wildlife after being shot.
CR2 9 Device detaches from arrow and attaches to wildlife upon impact.
CR3 3 The device functions in heavily wooded areas (2000 meters ideal. 300 meters minimal)
CR4 9 The device does not impede the accuracy of the shot, or at least produces repeatable deviations
CR5 9 The device does not impede the range of the shot
CR6 1 Tracker costs under $50
CR7 1 Arrow attachment is reusable up to five times
CR8 9 Arrow attachment "sticks" to wildlife with enough force to not fall off
CR9 3 Tracking is active for up to 12 hours. 3 hours minimal.
CR10 1 The arrow attachment is one piece
CR11 1 Arm/disarm feature for arrow attachment is present.
CR12 3 Used for for both deer and bear hunting
CR13 3 Durability/temperature resistance is suitable for Oct.-Dec hunting
CR14 9 Arrow attachment does not fall off due to force of the shot
CR15 9 User device tracks the location of the arrow attachment
CR16 3 Arrow attachment does not generate a sound when shot through the air

System-level and function-level requirements that define the intended performance of your system.

Constraints

Factors, usually system-level, that limit your design space (e.g., cost, total weight, total footprint, total power available)

Project Goals and Key Deliverables

Expected end result of the project, what the customer can expect to receive at the end of the project.

Solution Parking Lot

During the Problem Definition phase, you will start coming up with possible solutions. Rather than act on those now, put them in the Solution Parking Lot, and come back to them after your team has fully defined the problem.
