1991 14%
1992 17.5%
1993 18.8%
1994 15.5%
1995 17.0%

23%
Left voluntarily
18%

10%
Retired
19%
Promoted

IT Operations
Functions
Systems operators
operate hardware
schedule application runs
input / output preparation
Data-entry operators
Maintenance technicians
IT Operations Trends
Decreasing
hardware costs
“Lights Out” computer
rooms
Increasing PCs / workstations
Expert System (ES) technology
maintenance troubleshooting
Trends
Increasing use of
automated tools
Increase in complexity
Blaab’s Law:
“Old technologies persist in
the face of new technologies”
Improving Data Centers
Application functional
quality
how it meets user needs
Technical quality
how easy to maintain?
how efficient (MIPS)?
tension between these goals
Improve Centers
Application age
legacy systems
NNC study (1987)
inefficient centers - 8.7 years
efficient centers - 4.2 years
Legacy Systems
DT Study, 1995
65% legacy systems
slated for replacement
were to be replaced over
next 2 years
Legacy systems still a problem,
but not as significant
Improve Centers
Portfolio coverage
what % potential
applications are
actually developed?
beware of “hidden backlog”
NNC study:
inefficient centers - 24%
efficient centers - 40%
Improve Centers
Mix of Center staff:
NNC study:
inefficient centers more employees
greater % of them were
“hands on”
User feedback
Problem detection / correction
Issue
17% CIO turnover rate
per year AND 44% were
dismissed or demoted.
Why would you want
to be a CIO?
How can you be a
“CIO Survivor”?
What do you think?
Center Economics
“Charge-back” mode
no operating budget
charge clients for services
clients can shop elsewhere
centers can spend
what they collect - NO MORE!
Increasing quality
at decreasing cost
Center Economics
Economies of scale
BIG IS BETTER!
Gorch’s Law
IP = IC ** 2
where:
IP = increase in computer power
IC = increase in computer costs
Used as barrier to PCs in 1980s
Center Economics
Gorch’s Law works with
Data Centers because:
Mainframes more efficient
than PCs for large volumes
3GL more efficient than 4GL
Telecommunications value =
n (n - 1) where n = # nodes
Larger network more effective
Center Economics
Typical efficiency measures
Use Millions of Instructions
per Second (MIPS)
Hardware Costs per MIPS
Storage Costs per MIPS
Software Costs per MIPS
Teale Data Center “Real Decisions”

Center Economics
Teale Quality goals:
> 99.9% availability
4 hour network Mean
Time to Repair (MTTR)
Subsecond transaction response
Immediate Help Desk assistance
Center Economics
Strategies
Upgrade to latest
equipment / software
Consolidation
Outsourcing
Center Consolidation
Chase Manhattan Bank
100 data centers into 58
Saved $58 million in 2 years
First Interstate Bank
13 data centers into 2
reduced staff 2300 to 700
lowered overall budget by
$93 million
Center Consolidation
JC Penny
20 data centers to 4
Save $11 million a year
State of Wisconsin
12 data centers into one
Goal: save $1 to $3 million a year
exempted from state
procurement laws
Outsourcing IT
Functions
WHY?
overall business trend
global competition
value-added criterion
Would customer pay for this?
need for technical specialist
employee costs (fringe benefits)
Outsourcing Types
Professional services
(consulting)
Services (training / data entry)
Temporary employees
contract programmers
Transactions (credit reports)
Systems integrators
When to Outsource
Activity not strategic
Save at least 15%
Need technology specialists
Increase financial flexibility
capital to operating expenses
free personnel for development
acquire new technologies quicker
Consolidate,
Transfer
Internally

Outsource Failures
DT Study, 1995
Vendor expertise and
sophistication
Cost reduction
Improved delivery quality
Increased focus on
core competencies
Balance sheet improvement
Issue
What IT functions in your
company have been
or should be outsourced?
Why?
What obstacles were there
(or are there) to outsourcing?
Network Mgmt Scope
Fault handling
Performance monitoring
Change (project) management
Tactical (future) planning
Cost control
Network Mgmt Trends
Emerging standards
Integration as a goal:
different networks (LAN / WAN)
different vendors
Combine with management of
computers
“finger pointing”
Network (Cont.)
Distributed applications
client / server
Oracle’s Lotus Notes
Increased automation
Increased outsourcing
Contingency Mgmt
NOT disaster recovery
reactive, not proactive
Worst case scenario
all our eggs in one basket
natural disaster
human error / sabotage
Contingency Mgmt.
Methods
