Looking for someone to blame. Being faced with a problem becomes a problem. The reason we don't feel comfortable dealing with conflict is because a feeling of something-bad going to happen plagues us. Little do we know that the goal of a good problem-solving process is to make us competent enough to tackle problems. Any relationship, be it personal or professional is bound to have problems.
Problems are nothing but opportunities to improve the system and the relationships.
If you look at problems under this light, then you will not get worried about dealing with a problem. The most common mistake in problem solving is trying to find a solution right away. That's a mistake because it tries to put the solution at the beginning of the process, when what we need is a solution at the end of the process. Identify the issues. Be clear about what the problem is.
