The Information Technology Civil Engineering (ITCE)   approach is suggested to clarify the multiple direction of EA and keep it simple as the paradigm of resolving  stove pipe system rather than an umbrella of various disciplines.   Enterprise Architecture was initiated to resolve the challenge of stove pipe system, but under the title of " Enterprise Architecture", EA has been perceived  as the central planned  enterprise blueprint , or the enterprise wide  large scale  system architecture development ;  or the enterprise wide business process reengineering .  Following the experience that central planned economy approach which do not serve well even in the socialism countries; Most large scale system development have very limited success in  the past,; and  over 70% of  the enterprise wide business process reengineering effort have failed,  it is not difficult to understand why  EA has  not matured as expected because  It is the  collection of all the difficult challenge. 

 ITCE  resolve the stove pipe system by looking for commonality between  the differences. After all,  nothing is completely new under the sun and there commonality between different stove pipe systems.  It establishes the enterprise common services rather than design the entire enterprise similar to the city planners and Civil engineers where they design the common services such the road, power, water  and sewer systems rather than design every house in the city.   ITCE  is the "IT city planning and civil engineering" , it is all about people and  architecture buy-in from the stakeholders has being the major challenge to  serve the people oriented community.   City planners overcome the challenge of architecture buy-in by conducting he master planning of the enterprise and establish the public work to support each individual business owner's need rather than design every house in the city.  ITCE establish the enterprise IT infrastructure, manage the information resources and provide the services to enable the agility in supporting the dynamic of localized business process reengineering. 

The ITCE  approach is proposed  with a set of models, frameworks and roadmap as shown in the following exhibit.  It is  derived from the research effort  that EA is an emerging paradigm rather than a collection of various disciplines; it establish the service rather than the  entire enterprise; suggest to establish the services by leverage on common experiences from different established patterns; Overcome the architecture buy-in by building consensus to empower the legitimacy of  enforcement; Achieve the practical use with  via full  communicate with stakeholders.

e-CIO is a proto type with database and web technology on the implementation of ITCE  to go beyond research and discussions.  It demonstrate the use of ITCE  with integrated CIO automation.  "Interoperability begins at CIO",  most of CIO office still have stove pipe solution in the CIO business process. It is not very convincing to the stakeholder with the notion of " Do what I say and do not do what I do."
