- Benchmark against “fish feeders” that are on the market today (Fish Mate F14).
- Brainstorm ideas on how to adapt a product meant for dry food to accommodate live bait.
- Perform extensive testing to validate subsystem concept.

25. Phase review and efficiency
Reasons for Inefficiency:
Didn’t understand scope
Inefficient methods
Task not delegated to enough people
Ways we Improved:
Created new methods (ex PUGH)
Split up tasks and asked for help
Ways to be More Efficient in the Future:
Be honest about how large a task is
Be realistic about time to complete
Always update progress on time
