The effectiveness of management information depends on four characteristics:
1. Quality: The information must be accurate and reliable. If not, the solution of the problems will generate new problems.
2. Completeness: The information must be enough to allow the decision maker to make the right decision but not so much as to confuse the issue. Today, having excessive information rather than too little is a significant problem for business managers.
3. Timeliness: Managers can reach the information rapidly and on time. E-mail, instant messaging, and other social media tools make it possible for companies to hear about a problem immediately.
4. Relevance: Every decision maker needs a different variety of information. However, the problem is to have too much data by information systems.  ecision makers must be careful about the questions they ask to get the answers they need.
