Risk Assessment
High Level Risk Mitigation
Solenoid force and throw specifications do not meet required needs for shift.
Investigate other manufacturers or revert back to pneumatic system.
Current draw for solenoid is not available from system with all running components.
Investigate other solenoid manufacturers, add an aftermarket stator.
Control software not able to efficiently keep gear count.
Research gear solenoid sensor.

Current State of Design
• Design expected to meet all customer needs – Test Plan being developed to measure all specifications
• Project prototype budget on target
– Prototype Budget $1300– Material Costs $590 (form B.O.M.) –All shipping and fabrication pricing TBD
• Schedule – Design drawings need to be finalized – Parts need to be ordered (no major lead times have been
identified) – Machining schedule to be developed
•All other deliverables/mitigations – Conduct meetings with Brinkman about machinability and
timeline – Documentation – Evaluate all Customer Feedback
