You may want to keep a personal journal of ideas and observations about systems analysis and design while you are studying this book. Use this journal to record comments you hear, summaries of news stories or professional articles you read, original ideas or hypotheses you create, and questions that require further analysis. Keep your eyes and ears open for anything related to systems analysis and design. Your instructor may ask you to turn in a copy of your journal from time to time in order to provide feedback and reactions. The journal is an unstructured set of  personal notes that will supplement your class notes and can stimulate you to think beyond the topics covered within the time limitations of most courses.
