This study introduces the scenario-based engineering process (SEP) for defining user requirements and system specifications in healthcare. SEP enhances communication and promotes reusable software architectures for evolving health systems.

Area of Science:

  • Software Engineering
  • Health Informatics
  • Systems Architecture

Background:

  • Health care professional workstations are vital in large-scale health systems.
  • Standardized interfaces and protocols are needed for reusable software components.
  • Managing complexity in health care software requires engineering principles and abstraction.

Purpose of the Study:

  • To introduce a new method, the scenario-based engineering process (SEP), for evolutionary determination of user requirements and system specifications.
  • To promote the use of domain-specific software architectures (DSSAs) for specifying standard interfaces and protocols.
  • To leverage object-oriented design, graphical structural specifications, and formal component behavioral specifications.

Main Methods:

  • Development and demonstration of the scenario-based engineering process (SEP).

Related Experiment Videos

  • Utilizing an ambulatory care scenario with associated models to illustrate SEP.
  • Applying health care terminology and providing patient and provider system views within the scenario.

    • Main Results:

    • Scenario view abstractions facilitate consistent interdisciplinary communication.
    • Hierarchical object-oriented structures offer abstractions for reuse, understandability, and long-term evolution.
    • Integration of SEP and health care DSSAs into computer-aided software engineering (CASE) environments is proposed.

    Conclusions:

    • SEP provides a structured approach for defining requirements and specifications in health care systems.
    • The proposed methods support the creation of adaptable, reusable, and understandable health care software.
    • Integration with CASE tools can accelerate the development and certification of individualized health systems.
