CRM (Customer Relationship Management)

CRM is a system for centrally managing customer information and building long-term relationships. Key functions include customer data, purchase history, inquiry history, and email distribution. Notable services include Salesforce and HubSpot.

ERP (Enterprise Resource Planning)

ERP is an integrated core business system that consolidates all company operations—such as accounting, HR, inventory, sales, and production—into a single system. This eliminates duplicate data entry and enables real-time visibility into business performance. Well-known services include SAP, Oracle ERP, and Microsoft Dynamics 365.

SCM (Supply Chain Management)

SCM is a system that optimizes the flow of goods and information from raw material procurement through manufacturing, distribution, and sales. Its goals include reducing inventory, shortening delivery times, and improving demand forecasting accuracy. Recently, demand forecasting integrated with IoT and AI has been increasing; more details are covered in What is IoT.

SFA (Sales Force Automation)

SFA is a sales support system that visualizes and automates the progress, deals, and performance of sales activities. It is often offered as a subset of CRM, with functions such as opportunity management, quoting, and budget vs. actual management.

Key Points for the IT Passport Exam

In the IT Passport exam, questions matching the four abbreviations to their target business areas are common. The key differentiator of ERP is its "company-wide integration." Also, note the difference between CRM and SFA: CRM handles overall customer relationships, while SFA focuses specifically on sales activities.

Typical Past Exam Question Patterns

Study Tips

The four abbreviations are easy to remember when linked to: "Customers (CRM), Company-wide (ERP), Logistics (SCM), Sales (SFA)." The one-line keyword for ERP is "company-wide integration." Remember SCM as the flow of goods, and distinguish CRM and SFA by their focus on customer relationships versus sales activities.
