The Adaptive Enterprise Business and IT synchronised to capitalise on change

Business

Information Technology Business benefits: simplicity, agility, value November 26, 2009

Learn to love what you’ve been taught to fear… Change is constant • Everyday events send ripples throughout the organisation, and the IT that supports it. Change is unexpected • A merger, new market opportunity, sudden shift in competitive landscape, new partner. Change is disruptive • The goal is to minimise the impact of disruptions with an IT environment that is synchronised with the business. Change presents opportunities • The ability to adapt to change is a key advantage in business. To survive, compete and win, enterprises must adapt. November 26, 2009

Brings standardisation to the entire IT environment



Eliminates vertical islands



Embraces heterogeneity and legacy IT environments



Uses automation to scale and reduce complexity



Virtualises all IT assets



Helps convert fixed costs to variable costs

Adaptive Enterprise Design Principles • Reduce number of elements

Simplification

• Eliminate customisation • Automate change

+ • Use standard technologies and interfaces

Standardisation

• Adopt common architectures • Implement standard processes

+ • Break down monolithic structures

Modularity

• Create reusable components • Implement logical architectures

Applied consistently across: •

Business processes



Applications



Infrastructure

+ • Link business and IT

Integration

• Connect applications and business processes

How Do We Define Solution Architecture? Solution architecture is the essential, unifying concept of an information system and its effective deployment into an operational environment to solve a key business problem. • Benefits

− Aligns business and information contexts with architectural decisions − Ensures the solution that is built matches requirements, and will evolve with changing business needs − Provides a complete, clearly-scoped solution November 26, 2009

CIO Balancing Act Increase agility: •

Maximise return: •

Improve business results; grow revenue and earnings, cash flow, and reduced cost of operations

Enable the business organisation and operations to adapt to changing business needs

Improve performance: Mitigate risk: •

Ensure security and continuity of internal business operations, while minimising exposure to external risk factors

November 26, 2009

Improve business operations performance end-to-end across the enterprise • Increase customer and employee satisfaction •

The Four ITSA Views — Building a House Analogy Business view Why do I want a new house?

Technical view How will it be built?

• residence, entertainment, business • affordability • location • independence • image

• foundation, framing, heat/ac, plumbing, ... • utilities: - electric, water, comms, roads • security systems • controls • materials

Functional view What should the new house give me?

Implementation view With what will it be built?

• • • •

• sourcing - suppliers - specific models • financing • phasing • moving

uses / room layouts peace & quiet, security garden, trees garage, pet needs

Business View Why are we doing this? ty ili Ag

• Key

questions: oS Q st Co

− What are the internal and external drivers? − What are the business models and processes? − Who participates in the business processes? − What are the project goals? − How will the success of the solution be measured?

Functional View What should the solution do? ty ili Ag

Key questions:

st Co

• How will it be used and what services will it provide? • What information will it provide? To whom?

oS Q

• What will the completed solution do?

• What qualities must the solution have? sk Ri

Technical View How should the solution work? ty ili Ag

Key questions: • What are the interfaces and other constraints?

oS Q

• How will the system be structured and constructed? • What applications and data are needed?

st Co

• What does the infrastructure look like? • What standards will apply?

ITSA Framework The fundamental architectural elements of the ITSA framework are: •Business drivers, goals, and metrics (closely associated with the business view •Principles, models, and standards (associated with each of the four views)

In Summary The approach for creating solution architecture is: − Based on stakeholder participation − Organised as a set of four fundamental views − Motivated by key business drivers, goals, and metrics − Expressed as a set of principles, models, and standards − Linked to actions to ensure timely progress − Supported by an extensible framework of methods, tools, and techniques November 26, 2009

Solution Architecture Concept •A

rapid review of the key elements of a proposed solution, examining each of the four views − Focus on business drivers/goals, principles, models, and standards − Determine feasibility of an effective solution based on obstacles and constraints − Purpose: define solution’s conceptual architecture to facilitate well-informed, rapid decisions and get shared stakeholder understanding of, and commitment to, the proposed solution

Solution Architecture Blueprint

•A

detailed architectural description of a project, initiative, or enterprise architecture.

• Works

with you to:

− Establish an agreed-to, sufficient solution concept − Define, design, and document all essential features of the solution − Analyse the feasibility of the solution − Plan the implementation of the solution
