1. “Enterprise Architecture” is a term that applies to both a program and a deliverable/output. A company may have an Enterprise Architecture team that is responsible for creating an enterprise architecture. Considering everything you have read, discussed, and learned in this program, (a) describe the ‘Enterprise Architecture’ discipline or program, (2) describe the ‘enterprise architecture’ deliverable/output.

A) Enterprise Architecture defines the operations and structure of an organization. It provides a roadmap for how to transition an organization from its current state to future goals. EA has mechanisms in place to make sure that the IT deliverables align with the business requirements.

There are four main perspectives of EA – Business, application, information and technology .

Business – Describe all the processes and internal operations of the business on a daily basis.

Application – Describes how the organizations processes and standards all fit together.

Information – Documents all the data sources used by the organization, i.e. files, databases, spreadsheets, etc...

Technology – Defines all software, OS’s, servers, networking and hardware used in the organization.

EA is really about continuous communications between the business and IT on architectural choices, processes, and structure. It is an enterprise-wide view across business processes, applications and information technology. EA is enhanced when it’s baked into the organizations lifecycle. This includes project management, capital planning, strategic planning, and resource allocation.

B) The deliverables of EA will likely vary by organization. It depends on what framework the organization has chosen to use. For example the Zachman frame...

...ability, thereby allowing the business to more easily adjust to market conditions and other demands. EA also helps eliminate inefficient and redundant processes and to optimize and streamline current processes. The overall impact may be a reduction of employee turnover and cost savings with a more efficient well run enterprise.
IT experiences many benefits as well. Some of these benefits are that goals and objectives are more clearly stated, less rework occurs because of better communication and oversight. EA allows IT to deliver projects more rapidly, because constant business alignment ensures they are staying on track. EA also frees IT personnel to work on operation specific projects and innovations. More efficiency may encourage more innovation in the IT department and strengthen the technology infrastructure that can deliver cost effective results.

In this essay, the author

  • Explains that enterprise architecture refers to both a program and deliverable/output. a company may have an enterprise architecture team.
  • Explains that enterprise architecture defines the operations and structure of an organization and provides a roadmap for how to transition from its current state to future goals. ea has mechanisms in place to ensure it deliverables align with business requirements.
  • Describes all the processes and internal operations of the business on a daily basis.
  • Explains that information documents all the data sources used by the organization, such as files, databases, spreadsheets, etc.
  • Explains that ea is an enterprise-wide view across business processes, applications, and information technology. it is enhanced when it's baked into the organizations lifecycle.
  • Explains that at each perspective more sets of artifacts are produced.
  • Explains the mapping between erp, business intelligence, hrms, etc.
  • Explains that applications are easy to use and the underlying technology is transparent to users, so they can concentrate on tasks at hand.
  • Explains that bjs has hired multiple vendors (deloitte, ibm) to help build its system. they need to be sure each vendor is developing the system in a way that is easy for the user to understand.
  • Opines that standard specifications should be created and communicated with each vendor. if applications are not easy to use, users will be confused and bj will spend more time and money training employees.
  • Opines that technology changes should adhere to common standards and rules to encourage system-to-system communication.
  • Explains that bjs has multiple software systems and vendors. systems must be able to communicate and be compatible with each other regardless of platform.
  • Opines that vendors need to develop systems based bjs standards and procedures. technology must be developed platform agnostic and can work with other vendors software.
  • Explains the application architecture diagram of all the current business application software and how they communicate with each other.
  • Explains that information architecture identifies where all the organizations data is stored and how to access it.
  • Explains that strategic alignment is the business to it alignment that occurs when the businesses corporate side communicates with it leaders on costs and other potential impacts.
  • Explains resource management as a way to organize organizations more efficiently, so resources can be deployed on demand where needed.

  • Explains that governance is the exercise by which enterprise architecture is managed and controlled. it governance ensures that stakeholder's interests are considered and measurable results are produced.
  • Explains that ea governance sets in place design related policies, standards, guidelines, and procedures that must be complied with.
  • Explains that cost efficient processes adhere to common steps and workflows. manageable processes are measurable for quality purposes and help people optimize their performance.
  • Explains the value of enterprise architecture to the information technology organization and the enterprise as a whole.
