WEEK 1
Title: State of Enterprise Architecture Survey: Results and Findings
Reading:
Carr D., and Else S., 2018, State of Enterprise Architecture Survey:
Results and Findings. Enterprise Architecture Professional Journal
(Special
edition).
Overview : The article talks about the
survey of EA practitioners, conducted by EA Principals and the
Enterprise Architecture Professional Journal to
better understand
how the EA discipline is changing over time and how its relevance will
be seen by the practitioners in the future.
Learning Objectives for Week 1.
• Introduce Basic Enterprise Architecture Terminology;
• Define the concept of Enterprise Architecture;
• Explore the relationship between Enterprise Architecture and Applications
Key Questions
• What is current state of EA?
• What will be the future of EA as perceived by practitioners?
• What value will implementation of EA provide to the organisation?
Summary
A
survey of practitioners had been conducted, to understand the current
state of EA discipline and to take informed decisions regarding its
future. A
series of questions were asked, for instance, what
metrics could be used to show how EA adds value to an organisation? or
what value could be
derived from EA and so on. Through the survey,
it was observed that the responsibilities of the EA are broad, with the
vision of having strong business-
IT alignment. Furthermore, there
has been very little consistency in the views of how to measure the
value of EA or the awareness of it. It is
recommended that
practitioners continue to learn about new approaches, tools and
techniques, share ideas to have a vibrant community, both locally
and globally.

Title: Creating value through business model innovation
Reading:. Amit R. & Zott C 2012. Creating value through business model innovation. MIT Sloan Management Review p.p. 41-49
Overview
This
article talks about how companies are shifting their focus to business
model innovation as an alternative to process or product innovation.
Furthermore, the article
discusses the current business model
practices, how to innovate the business model design and lastly,
interdependencies between business models.
Learning Objectives
• Understand the Core Concepts and Definitions
• Discuss Architecture Standards
• Introduce the Architecture Continuum
• Describe Business Operating Models
• Analyse Capability Maturity
Key Questions
1. What is business model innovation?
2. How are organisations benefiting through new business model design?
3. Why organisations are shifting their focus from process or product change to business model?
Summary
According
to a recent survey, to gain competitive advantage, many companies are
shifting their focus to new business models from product and process
changes as replicating
an entire business model can be difficult
than a single process or product. There are three main elements that
characterizes a companies business model- content (selection of
activities
to be performed), structure (the link between activities and their
sequences) and lastly, governance (who will perform the activities). In
order to design the right
business model, organisation should focus
on value drivers such as novelty, lock-in, complementarities and
efficiency that enhances the value-creation potential of the business
model.

• WEEK 2
• Title: Characterizing the Software Process: A Maturity Framework
• Reading: W2 Humphrey (1989). Managing the Software Process.pdf
•
Overview: The article discusses about the improvement in the software
process of organisation. The paper talks about the basic principles of
software
process management. Further, a maturity framework has been provided to
improve the software capabilities of the organisation. The
framework
discusses five level of maturity i.e. Initial, Repeatable, Defined,
Managed and Optimised. The key actions required in each phase has
been discussed.
• Learning Objectives:
• Understand the Core Concepts and Definitions
• Discuss Architecture Standards
• Introduce the Architecture Continuum
• Describe Business Operating Models
• Analyse Capability Maturity
• .
• Key Questions:
• 1. How organisations can increase the software capabilities?
• 2. What is a Maturity Framework and what are the key elements of the framework?
• 3. What are the steps which an organisation should follow to achieve the higher level of maturity?
• 4. How maturity framework plays a major role in process improvement?
• Summary:
•
Software development is an important part of any organisation and it is
important to consider it as a process that can be evaluated and
improved.
To improve the process in any organisation it is
important that an organisation takes steps like understanding the
current state, developing vision,
prioritising the process which
requires improvement, producing the plan and committing the resources.
In order to achieve this, Maturity
Framework is used which assesses
the current level of organisation and the steps which it should take to
achieve a higher level. Each level
provides a decent understanding
of what an organisation process looks like. For example, at an initial
level the program operates without any
formal procedure however, at
a managed level, organisations have a defined process and they could
measure the process. Process improvement
plays a major role in an organization’s success.

Summary
The
business model canvas’ main objective is to help companies effectively
manage strategy or create new opportunities for growth. Using the
business
model canvas can help companies to move beyond their
product-centric thinking, and instead lean towards ‘business model
thinking’. The business model
canvas encompasses nine key
components which help to provide structure for how companies can take a
broader perspective of their business model.

Summary
An
empirical study to understand enterprise architect professionals has
been done to understand their characteristics and their ambitions to
formulate
enterprise architecture. Ten Swedish organizations took
part in this study. A research model is used which consist of 5 driving
factors which are Role, Power,
Competence, Main Focus and Style of
Acting. The study explores impact of these factors on an enterprise
architect characteristics. Through the interview it was
observed
that roles of an architect are important to achieve organisational
goals, competence of an enterprise architect plays a major role in
promoting the
strategic capability of the org., while power to the
architect allows architect to make decision freely. Style of Acting of
an architect is important to convince
organisation about EA strategic capabilities while main focus of architects is a balance between IT and business.

Summary
Enterprise
architecture (EA) is nothing but a collection of special documents,
called as artifacts that describe various aspects of the organisation
from a
business and IT perspective. These EA artifacts could be
associated with different activities and the corresponding benefits and
blockers. Eight activity area such
as business capability modelling,
Road mapping and portfolio mapping, IT asset management, project
governance and so on have been mentioned which have
diverse artifacts, supported by activities that lead to various benefits and are hindered by blockers.

WEEK 4
Title: Can Enterprise Architecture be based on the Business Strategy?
Reading:
Kurnia S. Kotusev S. Dilnutt R. & Taylor P., 2020. Can Enterprise
Architecture be based on the Business Strategy? Proceedings of the 53rd
Hawaii International Conference on System Sciences 2020.
Overview
: The article explores the traditional concept of Enterprise
Architecture development being closely coupled with the development of
business
strategy, and suggests that Enterprise Architect
practitioners should seek additional information beyond just the
business strategy to better plan
corporate information systems.
Learning Objectives for Week 4:
• Discuss legacy environments
• How to establish architecture capability
• Understand the importance of the architecture vision
• Identify the business benefits realised through Enterprise Architecture
Key Questions
• What is the actual role of the business strategy in supporting EA initiatives?
• What other inputs may be necessary or desirable for EA initiatives?
Summary
This
article posits that there are four key problems with taking business
strategy as a basis for EA initiatives. These four key problems include
the
absence, vagueness, volatility or short-term direction of some
business strategies. This article suggests that EA practitioners should
find alternative data
sources (e.g. informal discussions, improved
IT governance) to serve as additional input into the effective design of
corporate information systems.

Week 4
Title: How does Enterprise Architecture Add Value to Organisations
Reading:
Tamm, T., Seddon, P. B., Shanks, G., & Reynolds, P. J. 2011. “How
Does Enterprise Architecture Add Value to Organisations?,”
Communications of the Association for Information Systems (28:1), pp. 141–168.
Overview:
The article talks about the EA benefits and why it is useful for
organisations. The paper further discusses the EABM model
and it
proposes that EA leads to organisational benefits through its four
benefit enablers. The article discusses the future prospect of
this model.
Learning Objectives: Week 4
• Discuss legacy environments
• How to establish architecture capability
• Understand the importance of the architecture vision
• Identify the business benefits realised through Enterprise Architecture
Key Questions:
• 1. How EA could benefit an organisation?
• 2. Explain EABM and its component in detail?
• 3. How each benefit enabler contributes to an organisation?
Summary:
The EA Benefits Model shows that it is through improvements in Organisational Alignment, Information Availability, Resource
Complementarity
and Resource Portfolio Optimisation that EA leads to organisational
benefits. Although several other factors that
benefits have been
suggested, no study appears to have systematically compared the
different factors. However, large organisations
with a complex IT
environment, whose business model favors high levels of
organisation-wide standardisation and integration, will
benefit the most from EA.

The paper focuses on using pace layer strategy for CRM customer
service. It provides in depth information of each layer
contribution
to customer service. The paper discusses use of pace layer strategy to
assess current and future state model for customer services
and support application.
Learning Objectives: Week 5
•
Understand that an organisation’s application portfolio consists of a
wide variety of larger and smaller systems, that evolve and are
replaced at a different pace.
• Define Enterprise Resource Planning
• Explore the rationale for customisation of packaged software.
• Discuss the use of industry-specific add-on modules and specialised applications
• Recognise that organisations are continuously experimenting with new and better ways to leverage IT
Key Questions:
1. How pace layer can help in assessing application capabilities to achieve high customer expectations?
2. What is the reason that application moves between different layers of pace layer strategy?
3. What are the key factors of pace layer which needs to be considered while assessing applications current and future state?
Summary:
Pace
layer strategy provides a platform to the organisations for assessing
their business capabilities. Many applications stops at system of
records
without utilising the extended capabilities which could provide better
service and support. Pace layer strategy could be used to assess
the current state and create a future-state model. It also helps in measuring the usability of the applications.

Title: A Pace-Layered Integration..
Reading: Toomey, D 2018 A Pace-Layered Integration. Deloitte Platform Economics. Retrieved 27/7/2020 from:
https://platform.deloitte.com.au/articles/a-pace-layered-integration-architecture.
Overview:
This article provides the core understanding of Pace Layer Model. It
further explains each component of pace layer in terms of enterprise
architecture
and how it exists in an organisation. The paper further discusses, how
these layers can be integrated and why it is important for organisation.
Learning Objectives
• Understand that an organisation’s
application portfolio consists of a wide variety of larger and smaller
systems, that evolve and are replaced at a
different pace.
• Define Enterprise Resource Planning
• Explore the rationale for customisation of packaged software.
• Discuss the use of industry-specific add-on modules and specialised applications
• Recognise that organisations are continuously experimenting with new and better ways to leverage IT
Key Questions
• What is pace layer model?
• What are the different layers and how they fits in an organisation?
• How these layers could be integrated and why it is required?
Summary
Pace
layer model could be used to explain the architecture of an
organisation. The article explains each layer by relating it with the
application in an
organisation. For example Proof of concept of any
new functionality is considered as System of Innovation. In systems of
differentiator, application
represent the processes which are
unique and are differentiators for the organisation. Systems of Records
are not unique and are the core capabilities of
an organisation. In
order to integrate these layers, sub layers of API could be used which
interacts with SOR’s. Systems of Differentiation and Systems of
Innovation
use external and internal api’s to interact with each other. Best
practices to maintain adaptive integration helps in low cost changes and
formation of adaptive EA.

strategic business value from big data analytics. Journal of Management
Information
Systems 2018, Vol. 35, No. 2, pp. 388–423
Overview:
This paper discusses the importance of big data and how companies can
gain competitive advantages by leveraging and analysing it. This process
called Business Data Analysis (BDA) and defined as” the
application of statistical, processing, and analytics techniques to big
data for advancing business”(p
390). The main challenge
organisations face is “How to translate big data into commensurately
valuable information and business insights via BDA that justify
the
requisite investments?”. To answer this question, this paper try to
identify relationship between IT investment in BDA, BDA capability
building and strategic
value creation. In order to achieve that,
the author describe value proposition of big data analytics, and BDA
value creation and realization framework.
Learning Objectives: Week 6 learning objectives; Enterprise Applications Part 2
1. Define Business Analytics
2. Analyse Business Analytics and Competitive Advantage
3. Explore the Business Analytics Architecture
Key Questions:
1. What does include in big data infrastructure? How do organisations can leverage them?
2. What are the distinct targets of BDA value creation, and how eBay achieve the value through BDA?
3. What are the key challenges in the process of building BDA capabilities?
Summary:
With the identified business goals, organisations need to firstly
ensure that data sources are sufficient to be collected and
incorporated, then they
need to select appropriate frameworks and
platforms for the data transformation. The target of BDA include BDA
value creation are organization performance,
business process
improvement, product/service innovation and customer experience. The
capabilities of BDA are mainly restricted by data quality, data
integration,
data security and management issues. In detail, data quality might be
influenced by misspelled words, incorrect grammars and invalidity of
data.
And the challenge of data integration come from the
requirement of integrating data from different sources. Data security is
another challenge, which require
companies to confront with growing cyber-security threats.

Title: The Zachman Framework for Enterprise Architecture: An Explanatory IS Theory
Reading:.
Gerber, A, le Roux, P, Kearney, C, & van der Merwe1, A, 2020. The
Zachman Framework for Enterprise Architecture: An Explanatory IS Theory.
Springer Nature
Switzerland AG 2020.
Overview
The article
talks about the role of EA, the motivation to use Zachman framework
(ZFEA) and the nature of IS theories as defined by Gregor. It further
talks about mapping
ZFEA to Gregor’s theory (taxonomy and structural components) to determine if the framework can be served as an IS theory.
Learning Objectives
• Introduce The Zachman Framework
• Discuss the rules and structure of the framework
• Understand the horizontal and vertical framework perspective
• Explore the Information and Strategy dimensions of the Framework
• Understand the various business modelling requirements.
Key Questions
1. What is Zachman Framework?
2. How can Zachman Framework be regarded as explanatory theory?
Summary.
The
Zachman Framework for Enterprise Architecture (ZFEA) is a descriptive,
holistic representation of an enterprise for the purposes of providing
insights and understanding
of different aspects in an organisation.
Each row, column and cell in the architecture supports one another for
instance, technology will support the business processes, the
business
process in turn supports the application and the application the
strategy. According to Gregor, “theory allows for different perspectives
and aims to enhance the
understanding of the world by providing
explanation, description, prediction and actionable guidance”.
Similarly, It is right to the say that the ZFEA framework serves as an
explanatory IS theory as it provides a fresh perspective and a lens
for viewing the enterprise which could then lead to make a focused
strategic organisational research.

Week 7 - Zachman Architecture Framework : Part 1
Title: Framework for Information System Architecture
Reading:
Zachman, J. A. 1999. “A framework for information systems
architecture,” IBM Systems Journal (38:2&3), pp. 454–470.
Overview
This
article defines information systems architecture by creating a
descriptive framework from disciplines quite independent of information
systems, then by analogy specifies
Information systems architecture
based upon the neutral, objective framework. Also, some preliminary
conclusions about the implications of the resultant descriptive
framework are drawn. The discussion is limited to architecture and does not include a strategic planning methodology.
Learning Objectives Week 7: Components of EA The Zachman: Framework Part 1: Strategy and Information
• Introduce The Zachman Framework
• Discuss the rules and structure of the framework
• Understand the horizontal and vertical framework perspective
• Explore the Information and Strategy dimensions of the Framework
• Understand the various business modelling requirements.
Key Questions
1. What is Information System Architecture?
2. Why do we need a framework for information system architecture?
3. What are the risks for developing architectural representations?
Summary
By
studying fields of endeavour external to the information systems
community, specifically those professions involved in producing complex
engineering products (e.g.,
architecture/ construction,
manufacturing, etc.), it is possible to hypothesize by analogy, a set of
architectural representations for information systems. The resultant
"framework for information systems architecture" could prove quite valuable for:
• Improving professional communications within the information systems community.
• Understanding the reasons for and risks of not developing anyone architectural representation.
• Placing a wide variety of tools and/or methodologies in relation to one another.
•
Developing improved approaches (including methodologies and tools) to
produce each of the architectural representations, as well as possibly
rethinking the nature of the
classic "application development process" as we know it.

•
Overview: The paper provides insight of how two speed architecture
plays a role in defining the business capabilities for an organisation.
The paper discusses how two speed architecture could be beneficial and what is the need of using it.
• Learning Objectives:
• Explore the Process, People, Network, & Time dimensions of the framework
• Understand the various business modelling requirements
• Identify the Issues, Benefits and Risks of EA
• Key Questions:
• 1. How organisations can leverage two-speed architecture?
• 2. How business capabilities of an organisation plays a major role in working of two-speed architecture?
• 3. Can two-speed architecture be standardised? If not, explain why?
• Summary:
•
It is important for companies to take capabilities driven approach to
deploy technologies and manage other business issues. The profit of
two
speed architecture could help an organisation to balance resources,
mitigate risks and better trade-off between different business
capabilities. It helps architecture to be managed at different speed to accommodate processes and organisational requirements.

transformation of System-of-Systems architecture models using Zachman
framework. Journal of Industrial Information Integration 7 (2017) 33–43.
Overview
: The Zachman Framework, as well as TOGAF and FEAF, are suitable
architecture frameworks for mitigating the architectural challenges
associated with disruption, because they are flexible, adaptable and scalable frameworks.
Learning Objectives for Week 8:
• Explore the Process, People, Network, & Time dimensions of the framework
• Understand the various business modelling requirements
• Identify the Issues, Benefits and Risks of EA
Key Questions
•
What is the difference between the Zachman Framework and other
frameworks such as TOGAF and FEAF? How can they compliment each other?
Summary
This
article posits that disruptive innovation can create complexity for how
Enterprise Architects manage and design their architecture landscape.
Some
architectural frameworks (e.g. DoDAF and MODAF) may not
suitable for developing a disruption-proof architecture, as they are not
modular and open
enough to support the development of a flexible
and adaptable open system architecture. This article suggests that the
Zachman Framework and other
key architecture frameworks (e.g. TOGAF
and FEAF) may be appropriate architecture frameworks for designing with
disruption in-mind, due to their open
system approach.

1. Could an organisation follow a framework step by step to implement its recommendation in organisation?
2. What are the challenges an organisation faces while adopting a framework?
Summary
It
is evident that TOGAF is a widely used framework. However, it is
important to understand the actual implementation of the
recommendations
provided by TOGAF in an organisation. A study is
conducted at central Australian university to compare the original and
adapted TOGAF at
university. The research concludes that majority
of TOGAF prescriptions were not useful. The finding questions the value
of TOGAF as a standard
for EA and considered it as an Dictionary.

Title: Designing enterprise architecture based on TOGAF 9.1 framework
Reading:.
Qurratuaini, H., 2018. Designing enterprise architecture based on
TOGAF 9.1 framework. T2 - IOP Conference Series: Materials Science and
Engineering.
Overview
The article talks about the designing of
enterprise architecture. It is nothing but the target architecture to
be achieved, gap analysis between the initial architecture and targets,
as
well as project roadmap to assist enterprises in achieving the
desired target and solve their current problems. It further talks about
how TOGAF framework is used for designing
the architecture.
Learning Objectives
• Introduce the Architecture Development Methodology (ADM)
• Explore the ADM development Phases
• Business Architecture
• Information Systems Architecture - Data and Applications
• Technical Architecture
Key Questions
1. What are the benefits of TOGAF?
2. What are the different enterprise architecture design method?
Summary
Enterprise
architecture is the iterative process that aims to analyses the gap
between target state and current state, and provides a plan that
supports the enterprise’s
transformation from current state to the
future state. The key components required in designing enterprise
architecture for enterprises are based on 4 domains of architecture
i.e,
business, data, application, and technology with their prime focus on
defining and mapping the enterprise’s capabilities, integrating data and
system as a whole, and lastly,
assessing and planning the company’s
readiness to transform. In order to do this, there are four most widely
used frameworks in the industry such as Zachman Framework,
Gartner
Framework, Federal Enterprise Architecture and The Open Group
Architecture Framework (TOGAF). However, according to various studies
TOGAF has been considered a
better choice. The framework presents an
iterative and tested processes to develop the architecture. These
processes are further divided into different sections and phases such
as architecture vision, business architecture and so on.

International Journal of Information Technology Project Management (IJITPM), 11(1), 99-114. doi:10.4018/IJITPM.2020010106
Overview
: Enterprise architecture (EA) and project portfolio management (PPM)
are key areas when it comes to connecting enterprise strategy and
information
technology projects. A skillful understanding of the relationship
between these two areas is essential for effective IT planning.
Learning Objectives for Week 10:
• Overview the concept and structures of governance
• Introduce the TOGAF view of planning and governance
• Discuss the importance of planning
• Explore TOGAF Implementation governance
• Identify ten EA key success factors
• Understand the concept of risk management
Key Questions
•
How can/should Enterprise Architecture practitioners collaborate with
Project Portfolio Management stakeholders to ensure IT projects are
appropriately prioritised?
Summary
Alignment
between EA design and PPM is integral for sustaining a robust
information system architecture. This article introduces a conceptual
model to IT
project alignment that helps to integrate these two key
areas. The article highlights that the enterprise architecture domain
ascertains the technical goals
and constraints of an organisation,
whereas PPM determines the organisation’s business goals and
constraints. By combining knowledge from both areas,
organisations
can accurately propose, select, prioritise and schedule IT projects to
enable their architecture to meet the requirements of their
organisation. ISYS90043 Enterprise Applications and Architecture Readings Study pack 2020 21

Week 10 – Theme 4 Managing Architecture - Governance
Title: The Four Ways IT is Revolutionizing Innovation
Reading: Hopkins, M.S.2010. “The 4 Ways IT is Revolutionizing Innovation,” MIT Sloan Management Review (51:3), pp. 51–56.
Overview
The
article elaborates the role of IT in transforming the innovation
process and explains how it adds new meaning to the various facets of
innovation. The interviewee discusses why it
is significant that
organizations develop a heightened sense of agility to analyse trends
and demands that are rapidly changing and innovate accordingly. A
considerable change in
culture is inevitable to leverage the
benefits of IT. The article also lays down the key skills and
responsibilities that management executives must possess in the future
to ensure that
the organization does not fall behind.
Learning Objectives for Week 10:
• Overview the concept and structures of governance
• Introduce the TOGAF view of planning and governance
• Discuss the importance of planning
• Explore TOGAF Implementation governance
• Identify ten EA key success factors
• Understand the concept of risk management
Key Questions
1.What are the four dimensions in which IT can transform innovation?
2.How is IT redefining measurement of information?
3.Has the growth of technology altered the way that information is shared and to what extent?
4.How does the effect of IT in innovation alter the perspective of the management?
Summary
Innovation
in IT is the rising trend today redefining every process in business.
IT can aid and transform the innovation process in four dimensions,
namely, measurement,
experimentation, sharing and replication.
Collecting and analysing data, running IT experiments to achieve optimal
results, sharing information rapidly and replicating processes and
data
to achieve scalability drives organizations to improve and redefine
processes. To aid this trend, organizations must focus more on
responsiveness and agility rather than long-term
planning. However,
the key challenge lies in sifting through huge volumes of data to
identify crucial insights. Moreover, transforming the existing processes
to leverage the power of IT
requires significant effort by the organization so that they can move into the new era without breaking the current system.
