MODULAR DESIGN
iWave Systems Technologies
Modular Design…Wikipedia
Modular design, or "modularity in design" is an approach that
subdivides a system into smaller parts (modules) that can be
independently created and then used in different systems to
drive multiple functionalities. A modular system can be
characterized by the following:
1. Functional partitioning into discrete scalable, reusable
modules consisting of isolated, self-contained functional
elements
2. Rigorous use of well-defined modular interfaces, including
object-oriented descriptions of module functionality
3. Ease of change to achieve technology transparency and, to
the extent possible, make use of industry standards for key
interfaces
Modular Design…Wikipedia
Besides reduction in cost (due to lesser customization, and less learning
time), and flexibility in design, modularity offers other benefits such
as augmentation (adding new solution by merely plugging in a new
module), and exclusion.
Modular design is an attempt to combine the advantages of
standardization (high volume normally equals low manufacturing
costs) with those of customization.
A downside to modularity (and this depends on the extent of
modularity) is that modular systems are not optimized for
performance. This is usually due to the cost of putting up interfaces
between modules
Examples of modular systems are Cars, Computers, Furniture, High rise
buildings, Telephone exchanges, etc.
