What are your greatest strengths?

A revised answer to a question I've already addressed:

• One of my greatest strengths is my ability to see the big picture and to understand my role in achieving company objectives. I collect data from several sources, analyze potential solutions, and create an action plan to achieve goals.
  
• I'm not deterred by problems and obstacles that arise in the process.
  
• I have excellent communication skills and work well with others.
