Study Notes

IT System Stakeholders

IT Staff: responsible for installing and maintaining the system
Medical Ethics Manager: ensures the system meets current ethical guidelines for patient care
Health Care Managers: obtain management information from the system
Medical Records Staff: responsible for ensuring system information can be maintained and preserved, and record keeping procedures are properly implemented

Requirements Abstraction

A company must define its needs in a sufficiently abstract way to allow multiple contractors to bid for the contract
The requirements must not pre-define a solution, allowing contractors to offer different ways of meeting the client's needs

User REQs versus System REQs

User Requirements: statements in natural language, diagrams of services and operational constraints, written for customers
System Requirements: structured document, detailed descriptions of system functions, services, and operational constraints

Importance of Requirements

Requirements form the basis for project planning, risk management, trade-off, change control, and acceptance testing
Without requirements, programming is the art of adding bugs to an empty text file

Defining Requirements Engineering

The subset of systems engineering concerned with discovering, developing, tracing, analyzing, qualifying, communicating, and managing requirements
The process of establishing the services that the customer requires from a system and the constraints under which it operates and is developed

Requirements Completeness and Consistency

Requirements should be both complete and consistent
Complete: descriptions of all facilities required
Consistent: no conflicts or contradictions in the descriptions of system facilities

System Architecture

Presents a high-level overview of the anticipated system architecture
Shows distribution of functions across system modules
Highlights architectural components that are reused

Software Requirements Document

Typical structure includes:
- System description
- Requirements
- Specification
- Interfaces to other systems
- System models
- System evolution
- Appendices (detailed, specific information related to the application)
Hardware requirements define minimal and optimal configurations for the system
