Case 2: JetBlue & the VA

Good IT processes are as important as hardware and software when it comes to creating business value

– Even smaller, less-critical processes can have ramifications of a large magnitude in the interconnected world in which we live

The IS developed by JetBlue in 24 hours, implemented during a crisis in 2007, is now a full-time system

An unscheduled system failure took down key applications in 17 VA medical facilities for a day

Page 39: Chap 001

1-39

Case Study Questions

Eric Brinker of JetBlue noted that the database

developed during the crisis had not been

needed before; the company had never

experienced a meltdown

– What are the risks and benefits associated with

this approach to IT planning?

Page 40: Chap 001

1-40

Case Study Questions

With hindsight, we know that the decision made

by Eric Raffin of the VA to not fail over to the

Denver site was the correct one. But, it involved

ignoring established backup procedures

– With the information he had at the time, what

other alternatives could he have considered?

Page 41: Chap 001

1-41

Case Study Questions

A small, undocumented change resulted in the

collapse of the VA system, largely due to the

high interrelationship between its applications

– What is the positive side of this high degree of

interconnection, and how does this benefit

patients?

Page 42: Chap 001

What is a System?

A system is…

A set of interrelated components

With a clearly defined boundary

Working together

To achieve a common set of objectives

By accepting inputs and producing outputs

In an organized transformation process

Page 43: Chap 001

1-43

Basic Functions of a System

Input

Capturing and

assembling elements that enter

the system to be

processed

Processing

Transforma-tion process

converts input into

output

Output

Transferring transformed elements to

their ultimate

destination

Page 44: Chap 001

1-44

Cybernetic System

All systems have input, processing, output

A cybernetic system, a self-monitoring, self-

regulating system, adds …

– Feedback… system performance data

– Control… monitoring and evaluating feedback

to determine whether a system is moving

toward the achievement of its goal

system is a subsystem

The larger system is an environment

– Several systems may share one environment

– Connected via a shared boundary (interface)

Types of systems…

– Open and Adaptive

Data Versus Information

Data are raw facts, typically about physical phenomena or business transactions

– Specifically, objective measurements of the attributes of entities

Information is data that was converted into meaningful and useful context for end users

– Aggregated, manipulated, and organized

– Analyzed and evaluated

– Placed in proper context for a human user

Recognizing Information Systems

Business professionals should be able to look

at an information system and identify…

– The people, hardware, software, data, and

network resources they use

– The type of information products they produce

– The way they perform input, processing,

output, storage, and control activities
