As a project manager, why is analysis an important aspect of the job?

Analysis is a skill which is important to most of the top management role. According to me, analysis is important to everyone so that things can be foreseen, risks can be avoid and achievement can be made easily and surely success lies there.

Any Project manager needs to analyze about the expectation of the client, should assess the skill of the team members and their interest and monitor the ongoing process, check for bad source if any.

For doing all these things, analysis skill is required. In absence of this skill, the team management, deadline achievement, success of project may get collapsed.
