What should Captain Jenkins do here?

To offera solution or alternative along with outlining the problem.

There is a need to offer a solution to the problem or an alternative solution if the first solution did not work. This is the best way that the issue can be resolved. There are instances when people just reprimand without offering what they think will be a workable solution, so nothing ends up being fixed.

Now, there are also situations wherein a new solution has already been offered, but people still do not want to accept the solution because they still feel that the original plan is the best. If people would learn to accept their mistakes, there are a lot of positive changes that may occur.
