HRM 3450 Tutorial 17 Notes – Complex System
Introduction
• A complex system may be divided into relatively independent components and analyzed
by different individuals, each a specialist in their own area.
• Thus a plumber can create a home water system component without concern for the
details of the electricia’s efforts.
• They can work together on the linkages that concern both of them, for example, the
wiring for the boiler in a hot water heating system.
• The system architect coordinates the different efforts.
• The role of an IT system architect is similar
• To work with finance experts on the finance component, marketing experts on the
marketing component, and so forth.
• When the goal of a project is to implement a system of some type, it is sometimes
convenient to view the components of a system as modules that can be implemented
independently, then linked together to produce the final result.
• This technique can simplify analysis, design, assembly, upgrading, and even repair.
• It also supports collaboration during the design process, since individual components
can be designed by different individuals using specifications for the interfaces.
• For example, a cell phone might consist of a computer control module, a memory
module
• A display module, an audio input/output module, a radio transmitter/receiver module
• A keypad/text input module, and a wireless networking module.
• Each component might have been developed by a different team.
• These modules, designed, constructed, and manufactured as individual assemblies,
properly interfaced, wired together, and mounted into a case, constitute the design of a
typical cell phone.
• They also represent the components that might appear in the system diagram for a cell
phone.
