Designing E-Government System Architecture using E-Government Process & Enterprise Architecture Framework

Generally governments’ e-Gov systems development contracts use rigid software development methods.

Analysts decompose functions from requirements into components for software developers to design a system.

This causes functional decomposition to coincide with each other, and deprives developers of a true software computation environment.

The e-GEAF designed in this book comprehends applications, and ensures that the enterprise activities and system context are understood.

There is currently no e-Gov process for guiding e-Gov system implementation.

Comparison of EAF have not been done to determine their weaknesses and to rectify them by developing a new EAF based on the existing weaknesses.

The book has designed e-GEAF that has no usage limit across the board by correcting the weaknesses of existing EAFs.

A four step process is used.

First step is proposing an e-Gov development process for eliciting e-Gov requirements.

Second step is comparing the existing EAFs to determine their weaknesses.

DoDAF emerged the best but still had weaknesses.

Third step is proposing a generic framework using DoDAF as the benchmark.

The fourth step is designing of a generic framework named e-GEAF.
