Study Notes

System Requirements

  • Functional requirements describe the system's behavior and functionality.
  • Non-functional requirements describe the system's characteristics, such as performance, security, and usability.
  • System requirements are the overall description of the system's functionality, constraints, and quality attributes.

Categorization of Requirements

  • Interface requirements describe interactions among systems.
  • Operational requirements describe how a system is installed, configured, monitored, and updated.
  • Environmental requirements describe characteristics of hardware, such as size, weight, power consumption, and operating conditions.

Consolidated Sales and Marketing System (CSMS)

  • The CSMS system consists of 4 subsystems.

  • Executive stakeholders are responsible for making strategic decisions.
  • A correct combination of stakeholders is internal, external, operational, and executive stakeholders.

Requirements Gathering

  • The purpose of gathering detailed information in system analysis is to understand the system's requirements.
  • The role of an analyst in defining system requirements is to identify and document the system's requirements.
  • Prioritizing system requirements is important to ensure that the most critical requirements are addressed first.

FURPS
