requisites


Successful eGovernment needs:


A Common ICT Architecture


SOA Governance


Master data governance


Inter
-
agency transactions


Mobile applications


International context

Whole

of
-
government approaches lead the way in vanguard countries


“The 2012 Survey finds that many Member States are moving
from a decentralized
single
-
purpose organization model, to an integrated unified
whole
-
of
-
government
model

contributing to efficiency and effectiveness.


The model aims at centralizing the entry point of service delivery to a

single
portal
where citizens can access all government
-
supplied services
, regardless of
which government authority provides them.


In some countries, the whole
-
of
-
government approach helps build a
transparent
government system

with interconnected departments and divisions
, feeding into
the funnel of greater government efficiency and effectiveness.”

Common ICT Architecture

Requirement statement


We need an application development
framework to build systems that are:


Web
-
based


Multiple channels


Transactional


Platform agnostic


Support Cabinet resolution on Free and Open
Source Software

Tools for Software Development

What is Open JIG?


A set of technologies to build web
-
based
transactional systems for government


A set of best
-
of
-
breed practices to manage the
software development lifecycle


A sample application which uses the entire set of
technologies


Documentation to guide developers through the
technology stack


FOSS or Open Content licenses, can be upgraded
to enterprise support
