# Usability and Completeness
The area of usability and completeness is ultimately focused upon the ability of the notebook being able to provide enough detail that a reader could recreate the team’s implemented solution.
Looking over the provided documentation could a reader recreate and build the finalized robot, a particular subsystem, or program the solution to perform a desired task.
While there isn’t a specific task a team can accomplish to show proficiency in this area, it ultimately comes down to how well everything comes together.
* Are design phases documented well?
* Are there CAD diagrams, sketches, or other images with parts lists that show how a solution can be built?
* Does the programming offer enough information to create a controllable solution?
