The people in an AIS are simply the system users. Professionals who may need to use an organization's AIS include accountants, consultants, business analysts, managers, chief financial officers, and auditors. An AIS helps the different departments within a company work together.
For example, management can establish sales goals for which staff can then order the appropriate amount of inventory. The inventory order notifies the accounting department of a new payable. When sales are made, salespeople can enter customer orders, accounting can invoice customers, the warehouse can assemble the order, the shipping department can send it off, and the accounting department gets notified of a new receivable. The customer service department can then track customer shipments and the system can create sales reports for management. Managers can also see inventory costs, shipping costs, manufacturing costs and so on.
With a well-designed AIS, everyone within an organization who is authorized to do so can access the same system and get the same information. An AIS also simplifies getting information to people outside of the organization, when necessary.
For example, consultants might use the information in an AIS to analyze the effectiveness of the company's pricing structure by looking at cost data, sales data, and revenue. Also, auditors can use the data to assess a company's internal controls, financial condition and compliance with the Sarbanes-Oxley Act (SOX).
The AIS should be designed to meet the needs of the people who will be using it. The system should also be easy to use and should improve, not hinder efficiency.
