Scenario
St. Christopher Consulting Please read this scenario prior to answering the question St. Christopher
Consulting started as an accounting and financial services company. It has expanded over the years
and is now a leading North American IT and Business Services provider. With numerous practice
areas and a multitude of diverse engagements underway at any given time, overall engagement
management has become challenging. The company does not want to risk its outstanding reputation
or its international certifications and CMM ratings. Senior partners must become team players,
working to support the broader needs of the company and its shareholders. The Enterprise
Architecture team has been working to create St. Christopher’s Enterprise Architecture framework
to address these issues. The team has defined a preliminary framework and held workshops with key
stakeholders to define a set of principles to govern the architecture work. They have completed an
Architecture Vision at a strategic level and laid out Architecture Definitions for the four domains.
They have set out an ambitious vision of the future of the company over a five-year period. An
Architecture Review Board has been formed comprised of IT staff executives and executives from
the major practice areas. The Chief Executive Officer and Chief Information Officer have cosponsored the creation of the Enterprise Architecture program. The Enterprise Architecture
framework is based en TOGAF 9. As the EA team prepare to formulate an Implementation plan, they
have been asked by the CIO to assess the risks associated with the proposed architecture. He has
received concerns from senior management that the proposed architecture may be too ambitious
and they are not sure it can produce sufficient value to warrant the attendant risks. Refer to the St
Christopher Consulting Scenario You have been assigned to the role of Chief Enterprise Architect.

Once the Solution Architecture has been assembled, it should be analyzed using a state evolution
table to determine the Transition Architectures.

C.
The EA team should create a consolidated gap analysis to understand the transformations that are
required to achieve the proposed Target Architecture. The EA team should gather information about
potential solutions from the appropriate sources. Once the Solution Architecture has been
assembled, it should be analyzed using a state evolution table to determine the Transition
Architectures. An interoperability analysis should be applied to evaluate any potential issues across
the Solution Architecture.
