Communicate

Communication is frequently blamed when people understand a problem is persisting, but they cannot pinpoint the exact issue.  Communication is effectively implemented when expectations of different stakeholders have been set, feedback channels are set, and the results are reviewed without blame assigned to anybody.  Be concise. It is never your job to tell a person every single thing you know. You should already have an understanding of what they need to know. Passing blame to others is not communicating.  It effectively shuts down any constructive dialogue.
