Technological and Financial Trends<br />

Moore’s Law<br />

o Moore suggested in 1965 that the number <strong>of</strong> transistors,<br />

and thus the power, <strong>of</strong> an integrated circuit (computer<br />

chip) would double every year while the cost remained<br />

the same<br />

o He later revised this estimate to a slightly less rapid<br />

pace: doubling every 18 months<br />

Price-to-performance ratio<br />

o Organizations will have the opportunity to buy, for the<br />

same price, twice the processing power in 1½ years,<br />

four times the power in 3 years, eight times the power in<br />

4½ years, etc…<br />

<strong>Technology</strong> and Organizations<br />

Impact <strong>of</strong> new technologies on organizations<br />

o Most organizations will perform existing functions at<br />

decreasing costs over time and thus become more<br />

efficient<br />

o Creative organizations will find new uses for information<br />

technology based on the improving price-toperformance<br />

ratio and thus become more effective<br />

o New and enhanced products and services will provide<br />

competitive advantage to organizations that have the<br />

creativity to exploit the increasing power <strong>of</strong> information<br />

technology<br />

Productivity Paradox<br />

Over the last 50 years, organizations have invested trillions<br />

<strong>of</strong> US dollars on IT<br />

o<br />

Total worldwide annual spending on IT in 2000 was 2 trillion US<br />

dollars, and is expected to be over 4.5 trillion dollars by 2005<br />

But is very hard to demonstrate that IT investments really<br />

have increased outputs or wages<br />

The discrepancy between measures <strong>of</strong> investment in<br />

information technology and measures <strong>of</strong> output at the<br />

national level is described as the Productivity Paradox<br />

Explaining the Productivity Paradox<br />

Economists have developed a variety <strong>of</strong><br />

explanations for the productivity paradox that can<br />

be grouped as follows<br />

o Data and analysis problems - hide productivity gains<br />

o Gains from IT - are <strong>of</strong>fset by losses in other areas<br />

o Productivity gains - are <strong>of</strong>fset by IT costs or losses<br />

Copyright © 2002 Turban, McLean and Wetherbe<br />

Data and analysis problems<br />

Productivity numbers are only as good as the data used in<br />

their calculations<br />

In service industries, such as finance or health-care<br />

delivery, it is more difficult to define what the products are,<br />

how they change in quality, and how to allocate<br />

corresponding costs<br />

Productivity gains may not be apparent in all processes<br />

supported by information systems<br />

A failure to consider the time lags between IT investments<br />

and IT benefits may underestimate the productivity impacts<br />

Offsetting the losses<br />

Sometimes IT produces gains in certain areas <strong>of</strong><br />

the economy, but these gains are <strong>of</strong>fset by losses<br />

in other areas<br />

o An organization may install a new computer system that<br />

makes it possible to increase output per employee<br />

o If the organization reduces its production staff but<br />

increases employment in unproductive overhead<br />

functions, the productivity gains from information<br />

technology will be dispersed<br />

Offsetting <strong>of</strong> IT costs and losses<br />

IT really does not increase productivity<br />

Might be a relationship between IT spending and<br />

corporate pr<strong>of</strong>itability<br />

o Support Costs<br />

o Wasted Time<br />

o Support Development Problems<br />

o S<strong>of</strong>tware Maintenance<br />

o Incompatible systems<br />

Evaluating IT<br />

There are multiple kinds <strong>of</strong> values, and the return on<br />

investment measured in dollar terms is only one <strong>of</strong> them<br />

Probability <strong>of</strong> obtaining a return from an IT investment<br />

depends on probability <strong>of</strong> conversion success and<br />

implementation factors into quantifiable measures<br />

The expected value <strong>of</strong> the return on IT investment in most<br />

cases will be less than that originally anticipated<br />

IT Appraisal Methods<br />

<br />

<br />

<br />

<br />

Financial approach<br />

o<br />

These appraisal methods consider only impacts that can be monetary<br />

valued – focusing on incoming and outgoing cash flows<br />

Multi-criteria approach<br />

o<br />

These appraisal methods consider both financial impacts and non-financial<br />

impacts that cannot, or not easily be, expressed in monetary terms –<br />

employing quantitative and qualitative decision-making techniques<br />

Ratio approach<br />

o<br />

These methods use several ratios (e.g., IT expenditures vs. total turnover)<br />

to assist in IT investment evaluation<br />

Portfolio approach<br />

o<br />

These methods apply portfolios to plot several investment proposals<br />

against decision-making criteria. The portfolio methods are more<br />

informative compared to multi-criteria methods and generally use fewer<br />

evaluation criteria<br />

Value <strong>of</strong> <strong>Information</strong>-2-Decision Making<br />

The value <strong>of</strong> information to decision making is the<br />

difference between the net benefits—benefits<br />

adjusted for costs—<strong>of</strong> decisions made using the<br />

information and decisions without the information<br />

Value <strong>of</strong> <strong>Information</strong> =<br />

Net benefits with information –<br />

Net benefits without information<br />

Intangible Benefits<br />

<br />

<br />

<br />

Financial analyses need to consider not just tangible benefits but also<br />

intangible benefits<br />

The most straightforward solution to the problem <strong>of</strong> evaluating<br />

intangible benefits is to make rough estimates <strong>of</strong> monetary values for<br />

all intangible benefits<br />

One approach to evaluating infrastructure is to focus on objective<br />

measures <strong>of</strong> performance known as benchmarks<br />

o<br />

Metric benchmarks provide numeric measures <strong>of</strong> performance<br />

- IT expenses as percent <strong>of</strong> total revenues<br />

- Percent <strong>of</strong> ―downtime‖ (when the computer is not available)<br />

- CPU usage (as percent <strong>of</strong> total capacity)<br />

o<br />

Best-practice benchmarks emphasize how information system<br />

activities are actually performed rather than numeric measures <strong>of</strong><br />

performance<br />

Total Cost <strong>of</strong> Ownership (TCO)<br />

TCO is a formula for calculating the cost <strong>of</strong> owning and<br />

operating a PC<br />

Cost includes hardware, technical support, maintenance,<br />

s<strong>of</strong>tware upgrades, and help-desk and peer support<br />

By identifying such costs, organizations get more accurate<br />

cost-benefit analyses and also reduce the TCO<br />

It is possible to reduce TCO <strong>of</strong> workstations in networked<br />

environments by as much as 26% by adopting best<br />

practices in workstation management<br />

Value Analysis<br />

Allows users to evaluate intangible benefits on a<br />

low-cost, trial basis before deciding whether to<br />

commit to a larger investment<br />

o Keen (1981) developed the value analysis method to<br />

assist organizations considering investments in decision<br />

support systems (DSSs)<br />

<strong>Information</strong> <strong>Economics</strong><br />

Focuses on the application <strong>of</strong> IT in areas where its<br />

intangible benefits contribute to performance on key<br />

aspects <strong>of</strong> organizational strategies and activities<br />

It incorporates the technique <strong>of</strong> scoring methodologies,<br />

which are used in many evaluation situations<br />

Scoring methodology is used by analysts to first identify all<br />

the key performance issues and assign a weight to each<br />

one<br />

Organizational objectives are used to determine which<br />

factors to include, and what weights to assign in the<br />

scoring methodology (tangible and intangible benefits)<br />

Outsourcing<br />

<br />

<br />

<br />

Many organizations may not be able to manage IT as well as firms<br />

that specialize in managing IT<br />

For such organizations, the most effective strategy is outsourcing<br />

o<br />

o<br />

Outsourcing is the process <strong>of</strong> obtaining services from vendors,<br />

rather than from within the organization<br />

The decision to outsource usually considers two factors:<br />

Since the late 1980s, many organizations are outsourcing the<br />

majority <strong>of</strong> their IT functions<br />

o<br />

In the mid-1990s, IBM, EDS, and Computer Sciences Corp<br />

were winning approximately two-thirds <strong>of</strong> the largest outsourcing<br />

contracts<br />

Offshore Outsourcing<br />

Offshore outsourcing <strong>of</strong> s<strong>of</strong>tware development<br />

has become a common practice in recent years<br />

o<br />

About 33% <strong>of</strong> Fortune 500 companies have started to outsource<br />

s<strong>of</strong>tware development to s<strong>of</strong>tware companies in India<br />

Outsourcing Advantages<br />

<br />

<br />

<br />

<br />

<br />

<br />

Financial<br />

o<br />

Avoid heavy capital investment, thus releasing funds for other uses<br />

Technical<br />

o<br />

o<br />

Be freer to choose s<strong>of</strong>tware due to a wider range <strong>of</strong> hardware<br />

Achieve technological improvements more easily<br />

Management<br />

o<br />

o<br />

Concentrate on developing and running core business activity<br />

Delegate IT development (design, production, and acquisition) and<br />

operational responsibility to supplier<br />

Human Resources<br />

o<br />

o<br />

Draw on specialist skills, available from a pool <strong>of</strong> expertise<br />

Enrich career development and opportunities for staff<br />

Quality<br />

o<br />

o<br />

Clearly define service levels<br />

Improve performance accountability<br />

Flexibility<br />

o<br />

o<br />

Respond quickly to business demands<br />

Handle IT peaks and valleys more effectively<br />

Outsourcing Risks<br />

Shirking occurs when a vendor deliberately underperforms<br />

while claiming full payment<br />

o<br />

Billing for more hours than worked, providing excellent staff first<br />

and later replacing them with less qualified ones<br />

Poaching occurs when a vendor develops a strategy and<br />

strategic application for a client and then uses them for<br />

other clients<br />

o<br />

Vendor redevelops similar systems for other clients at much lower<br />

cost, or vendor goes into client’s business<br />

Opportunistic re-pricing occurs when a client enters into a<br />

long-term contract with a vendor and vendor changes<br />

financial terms at some point or overcharges for<br />

unanticipated enhancements and contract extensions<br />
