Info

Think about the follow categories when creating a list of risks:

Technical: Requirements, Technology, Interfaces, Performance, Quality

External: Customer, Contract, Market, Supplier

Organizational: Project Dependencies, Logistics, Resources, Budget

Project Management: Planning, Schedule, Estimation, Controlling, Communication

🟩 added to Analysis and Response

🟩 Part delivery is much slower than expected, pushing back testing and therefore project deadlines
Members miss deliverable due to increased work load
Schedule didn’t allow for multiple iterations to occur, now we’re stuck with a less-than-ideal product
🟩 The drone isn’t competitive
The drone crashing during competition
battery level low

Unanticipated electromagnetic shielding/interference on the frame, requiring electronics to be placed elsewhere
Bolts missing/coming off during flight
Landing gear fails on impact
Barbies are not secured properly in flight
Boards are not secured in flight
Water gets into the avionics compartment
Parts disconnect during flight (wings, tail)
Control surfaces fail
Motor failure
Sensors dislodged
Heat causing deformation of 3D printed parts
Mechanical failures (permanent deformation or breaking) caused by stresses
Elastic deformation of frame due to stresses
Imperfections in machined parts (3D printed brackets included) causing stress concentrations → fracture → propagate to fatal failure

Antenna towers fall over
Wires disconnect in inaccessible regions of the tower
Devices and equipment are damaged in transport, we only find out when we get there
Power failures
Controls loops failure
Antennas damaged by weather (hail, due to stresses from wind, water damage)
Over/undervolting by accident

Sens failure (glide)
autopilot failure (pilot takeover)
fly by wire failure
1. lost AHRS // no inertial nav → fatal failure
2. incorrect command deciphering → pilot disarm / takeover → fatal failure
3. control surface output inverted. → pilot disarm/takeover → fatal failure.
telemetry lost (follow VFR & divert)
1. telemetry modem failure
2. board modem module failure
3. software manager failure.
controls/PID failure
1. incorrect PID values
2. controls runaway (I term runaway?)
3. flipped motor direction
RC link lost (divert and glide)
Landing Pad not found
1. search → find?
heading lost
1. see 3, 6.
RF Interference from other teams/environment

Pilot failures

improper site assessment
- flying into obstacles // not being aware of restricted flight areas
improper communication
heat?cold?
dehydration

Risk Analysis (use to understand impact)

Risk Event	Related Subteam	Probability % (P)	Severity Rating (S)	*Risk Score (PS)**
	XXX
Crash the 6wk before comp rendering it irreparable	All (mostly mech)	Unlikely (35%)	Extreme (100)	High (60)

Risk Event	Risk Response	Assignee (RSE)	Andy fucks up	Don’t let Andy touch anything

Andy Meng Competition paperwork isn’t finished on time leading to not being able to compete	Sysint to make sure templates and the bones of the report is finished	Hamza Ali to finish the rough draft for the report
The competition drone doesn’t fly adequately enough to be competitive	Iterate designs and test code by scheduling test flights and organizing different key areas to test each flight	Aaron Dyck (Deactivated) schedule flights and help with organizing flights

Risk Event What happened?	Risk Impact What consequence(s) occurred?	Future Mitigation What can you do to prevent this from happening again?
Deadline for competition drone timeline went over	We don’t have a good way to keep track of deadlines, or see how other late deliverables affect the overall timeline	Prioritize tasks based on importance to not overwork members, while still getting the most important tasks finished
