  1. Managing Organizational Complexity: Enterprise Architecture and Architecture Frameworks with An Overview of their Products, Artifacts and Models Beryl Bellman, PhD FEAC Institute Academic Program Director California State University Professor bellman@feacinstitute.org

  2. What we will Cover • Complexity in Organizations and Emergent Behavior • Organizations as complex adaptive systems • A framework for agent models – The Zachman Framework as a Periodic Table of Elements • Enterprise Architecture and other major frameworks • Architecture models, products and artifacts • Emergent behavior and EA viewpoints • A case study showing the use of architectural models

  3. The Need for Enterprise Architecture The effective organization is “garrulous, clumsy, superstitious, hypocritical, monstrous, octopoid, wandering and grouchy" Karl Weick On Re-Punctuating the Problemin New Perspectives on Organizational Effectiveness; Jossey Bass 1977

  4. Making Sense of Organizations • This is because organizations organically emerge out of the communication patterns that develop in the course of doing business and in response to the host of environmental variables in dynamically changing business landscapes. • Enterprises are instances of complex adaptive systems having many interacting subcomponents whose interactions yield complex behaviors • Enterprise Architecture is a way of understanding and managing such complexity

  5. Dealing with Organizational Messes rather than Problems • In a real sense, problems do not exist. They are distractions from real situations. The real situations from which they are abstracted are messes. • A mess is a system of interrelated problems. We should be concerned with messes, not problems. • The solution to a mess is not equal to the sum of the solution to its parts. The solution to its parts should be derived from the solution of the whole; not vice versa. • Science has provided powerful methods, techniques and tools for solving problems, but it has provided little that can help in solving messes. The lack of mess-solving capability is the most important challenge facing us.” • Russ Ackoff, University of Pennsylvania

  6. An Order to the Mess • Hidden Order (John Holland) • Complexity and Chaos • Strange Attractors • Complex Adaptive Systems • Emergence of new organizational forms

  7. EA and Agent Based Models In this discussion we consider how architects develop models that integrate into enterprise architecture allowing queries to determine impacts on some proposed or actual technological or business process change in the complex organizational environments.

  11. TOGAF

  12. TOGAF and EA • There are four types of architecture that are commonly accepted as subsets of an overall enterprise architecture • A Business (or Business Process) Architecture - this defines the business strategy, governance, organization, and key business processes. • A Data Architecture - this describes the structure of an organization's logical and physical data assets and data management resources. • An Applications Architecture - this kind of architecture provides a blueprint for the individual application systems to be deployed, their interactions, and their relationships to the core business processes of the organization. • A Technology Architecture - this describes the logical software and hardware capabilities that are required to support the deployment of business, data, and application services. This includes IT infrastructure, middleware, networks, communications, processing, standards, etc.

  14. Business Architecture Data Architecture Program Management Strategic Planning Organization Structure Technical Architecture Application Architecture Enterprise Architectures in Perspective using Zachman FEAC Institute – Where Do These Architectures Fit?

  15. Contrasting Perspectives • Picking up the poker – Wittgenstein versus Popper • Does philosophy center on the resolution of puzzles posed by language or are there genuine problems to be resolved? • When we speak of solutions – do they pertain to puzzles or problems? Dave Edmonds & John Eidinow

  16. Contrasting Perspectives •   “All art — symphonies, architecture, novels — it’s all puzzles. The fitting together of notes, the fitting together of words have by their very nature a puzzle aspect. It’s the creation of form out of chaos. And I believe in form.” (Stephen Sondheim )

  17. Bob Napier, HP EVP & CIO “One of the things I’m passionate about ...  is having an Enterprise Architecture and making sure that everything we do fits the puzzle." Puzzles and Enterprise Architecture

  18. Resolving Puzzles • Modeling human communications from each of the three DoDAF perspectives and/or FEAF levels • Accounting for human communications from the top Zachman rows • Linking to infrastructures used to support them at every layer of relevant depth • Resolving conflicts as putting together pieces of a complex puzzle

  19. Architecture Views and Viewpoints FROM DIFFERENT ARCHITECTURE FRAMEWORK PERSPECTIVES

  20. Conceptual model of architecture description: content model

  21. Views and Viewpoints • A viewpoint is a way of looking at a system; a view is what you see (IEEE) • A viewpoint is the definition of the perspective from which a view is taken. It is a specification of the conventions for constructing and using a view. • A view is what you see; a view is where you are looking from – the vantage point or perspective that determines what you see (TOGAF 9)

Tieso

  28. Organizations and Nodes • Organizations can be considered as a set of interconnected nodes • Each node receives a defined input either coming from another internal node or the external environment • Each node processes inputs and emits outputs to other nodes See Miller and Page, Complex Adaptive Systems, pp 202

  29. Understanding Networks • Connectedness in organizations characterizes social networks within them. • The study of social networks has led to a field known as communication network theory, which analyzes relationships according to nodes • The study of networks in organizations or organizational network analysis offers an approach to understand complexity within the internal workings of an organization.

  30. Valdis Krebs pointed out how "organization charts prescribe that work and information flow in a hierarchy, but network mapping reveals [they] actually flow through a vast web of informal channels." • These informal channels points to significant differences between the formal organizational structural view and what is actually occurring in the daily life of the enterprise. • These differences have important impacts on how work gets done and allows analysis of emergent bottlenecks, inefficiencies and gaps in business processes. • These are represented in EA for determining how the information, data and technical architectures relate to the business. From McIntire School of Commerce

  31. Some Surprises in Analyzing Networks • In some organizations a few individuals may be in a highly interactive role connecting different sub-groups together. In a close examination of what is occurring sometimes we find these individuals function more as bottlenecks than enablers. • Once their functions within the organization are shared with other positions, information and work flow is made more efficient. • However, in some instances such boundary spanning positions are relevant, allowing close management of projects. What is important in network analysis is to uncover whether the structure is intentional and functional, or if they are emergent structures that impede the work and communication flows within the enterprise.

  34. The Emergence of Enterprise • An enterprise arises from local interaction of often independent units that exist within a common environment • Each unit or entity interacts with its immediate environment according to a set of low order rules • The combined effects of these lower order interactions within an environment gives rise to higher order organizational phenomenon such as organizational culture • Culture emerges from localized interactions • As culture is grounded at the local level, culture is highly resistant to change • Changing culture entails re-specifying local level rules rather than simply imposing change from the top • EA necessitates an enterprise-wide ethnography taking into account multiple perspectives • Creating an enterprise architecture proffers a mechanism to initiate positive change

  35. Growing Societies from the Bottom Up • We have briefly discussed how agent modeling can be described as sets of rules • These sets comprise different types of strategic interaction games, as exemplified in the classic example of the prisoner’s dilemma. • However in game theory focus has been on one game at a time. Using evolving automata cognitive behavior is modeled across multiple games. • This points to a games-theoretic model of enterprises as simultaneously playing out a series of games as constituting ensembles that impacts the strategy for any particular game. • EA is an approach for locating the underlying rule schema that underlie socially contextualized behaviors as systems • In this way we can run computational models that allow the traceability we suggested earlier between business process proposals and cultural assumptions that are entailed.

  36. Computational Modeling of Social Life • This recommends a new type of explanation for social and cultural phenomena • As Epstein and Axtell argue we should reinterpret the question of explanation by asking “can we grow it?” • They maintain that modeling “allows us to ‘grow’ social structures … demonstrating that certain sets of microspecifications are sufficient to generate the macrophenomena of interest.” • With this in mind social scientists “are presented with ‘already emerged’ collective phenomena and …seek microrules that can generate them • This is one way of conceptualizing the promise of enterprise architecture

  37. Complexity in Organizations • “One of the strengths of this type of simulation modeling is that it enables researchers to subject trial explanations for sociocultural phenomena to a rigorous test. • What is new about the adaptive agent approach is their ability to capture nonlinear effects that would otherwise be out of reach. • A more important development is the revelation, foreshadowed by theoretical work on complex adaptive systems, that social institutions can emerge from the bottom up as a result of feedback processes linking social actors to their environments”.

  40. Overview and Summary (AV-1)Excerpt • The Professional Golf Association (PGA) has offered Mr. Chipitin, owner/operator of Eagle Eye Golf Course, an opportunity to host a celebrity charity golf event in April 2012. • Purpose: To create a To-Be enterprise architecture that provides information on the activities, organizations, and systems necessary to support a new capability (e.g. host a celebrity charity golf event). • In doing so, the architecture also identifies new as well as existing primitives (e.g. op nodes, system nodes, etc.) that remain functional as they are today or that may need to be modified in support of the To-Be scenario. • This enterprise architecture is the first in a series of tasks that need to be performed as part of the overall decision making process for accepting or rejecting the PGA’s proposal to host the celebrity charity golf event at EEGC in April of 2012. • Viewpoint: Owner/Operator EEGC • Timeframes: To-Be • Timeframe for making decision to host or not is 6 months • Timeframe for event is April 2012 New Capability Enterprise Architecture for EEGC by Team ACIS
