Perhaps the issue partly stems from a lack of time. Our employees often have to rush to complete cases. I also think that human nature factors into the equation. We do our work and think that what was done is clear, but when someone else sees the work done, it is perhaps not so clear, especially when it comes to the underlying reasoning. Employees do the work required, but they do not provide sufficient documentation to support their reasoning, for instance, justifications for choosing a particular method and arriving at a specific conclusion.
