Safety
Low voltage/ Low current system will be
fairly harmless to users.
 Low power IR light is harmless.
 You can’t prove that RF signals are
harmful so HAH!
 Common sense.

Schedule
Risks
Unable to get parts.
 Price of adding feature is too expensive.
 Complexity of feature is too hard to
implement in a semester time frame.
 Scheduling issues.

Contingency
Modular system eliminates need some
compatibility issues since we will have a
communication protocol for between
components.
 Modular system we can drop a module
without having to completely redesign our
system.
 If a system can’t be implemented to
complexity we can remove that module for
the time being.
 SVN software/email/weekly meetings.
