Groupware and CSCW (Computer-Supported Cooperative Work)

Introduction

Groupware refers to software systems designed to support the collaborative work of teams and groups. Unlike individual productivity tools, groupware facilitates coordination, communication, and cooperation among multiple participants working toward shared goals.

Computer-Supported Cooperative Work (CSCW) is the broader field that studies how technology can support collaborative activities, encompassing both the technical and social aspects of group work.

Key Characteristics:

• Enables multiple users to work together on shared tasks
• Supports both synchronous and asynchronous collaboration
• Manages shared resources and information
• Facilitates communication and coordination among team members
