Motivation for modularity

Scalability & extensibility– Architecture with long view– Build/buy for current need– Extend in the future

Affordability– Buy only the pieces you need– Competition for the modules– Non recurring savings with reuse– Recurring savings on quantity

Accountability – Enables division of responsibility– Shortens cycle time

Electronic Modular Enclosures
