Why Organizations Need Apply Decision Support Systems / Business Intelligence?

Well from my opinion, why some company / organization need DSS and BI? it's because when we start a business and using manual process, like still write the sales report, purchasing report, and others that manually work. It make our business process not efficiency and accurate. But if we use DSS/BI system we can:

• Speed up the process of decision making
• Increase organizational control
• Speed up problem solving in an organization
• Help automate managerial processes
• Improve personal efficiency
• Eliminate value chain activities

And the most important thing is the entire decision-making process, from problem recognition to action, has become so accelerated it is simply impossible to rely on human response alone. That's why you need Business Intelligence to help you react and adapt to the constantly changing business environment.
