The Economics of IT Investments
Moore’s Law
         Moore’s Law
                            Year of introduction                                   Transistors

   4004                              1971                                         2,250

   8080                              1974                                         5,000
   8086                              1978                                         29,000
   286                               1982                                         120,000
   386™ processor                    1985                                         275,000
   486™ DX processor                 1989                                         1,180,000
   Pentium® processor                1993                                         3,100,000

Implications of Moore’s Law
   Price-to-Performance ratio is declining
       Existing functions will be done at lower costs
        (efficiency improvements)
       New uses for technology will emerge
         • Enhanced products and services
         • Make the technologically feasible economically
         • IT will be embedded in traditionally low-tech goods
       Provides competitive advantage to
        innovative companies
       Greater benefit to consumers
       Greater emphasis on intangible benefits
Intangible Benefits of IT

   Factors that are important but difficult to
    express in terms of monetary value
   Early days- easy to measure value
       Computers replaced manual jobs on a one-
        by-one basis
   Now… most manual tasks have been dealt
       Additional advantages come through re-
        engineering business processes
       BPR produces intangibles – better response
        time, better quality… difficult to measure
Productivity Paradox

   Despite massive investments in IT in the
    1970s and 1980s, there is lack of evidence
    of a payoff.
       Services showed much less productivity
        gains than manufacturing
   Difficult to demonstrate that the IT
    investments are directly correlated to higher
    wages or outputs
   The discrepancy between measures of IT
    investments and output measures is called
    the productivity paradox.
Explaining the Paradox
   Data and Analysis problems
        Difficult to allocate costs to products in the service sector
        Analysis does not take into account time lags (it takes time to learn
         new software – productivity may decrease…)
   IT gains are offset by losses in other areas
        Reduce production staff (due to IT) but increase staffing in other
   IT gains are offset by IT losses
   Is there really a relationship between IT spending and profitability?
        Strassman says “no evidence”
        What if IT causes outputs to increase 25 percent but inputs
         increase 30 percent?
        Evaluations must include changes in inputs over entire lifecycle
         (including projects not implemented)
          •   Support costs
          •   Wasted time
          •   Software development problems
          •   Software maintenance (remember Y2K?)
          •   Incompatible systems and integration costs.
Evaluating IT
Consider some of the costs and benefits associated with
acquiring a new software system

Value of IT Investments:
Keep in Mind
   Multiple kinds of values: ROI dollars is only
    one of them
   Different types of investments have different
    probabilities of providing returns
   Probability of return depends on probability
    of conversion (systems may not be be fully
    implement, over-budget, late..)
   Expected value of ROI is usually less than
    initially calculated

Traditional Evaluation
 Internal Rate of Return
 Net Present Value

 Payback period

 Cost-Benefit Ratio

 Total Cost of Ownership

Assessing the intangibles
   IT can
       Speed up business processes
       Provide more accurate information
       Improve communication
   Difficult to measure
       How do you estimate the value of email
   Approaches
       Value Analysis
       Information Economics
       Management by Maxim
       Option Valuation

Information Economics
   Focuses on key organizational objectives
   Uses a scoring methodology
   Process
      Identify all key performance issues
      Assign each a weight based on importance
      Every product being evaluated receives a score (0-
        100) on each factor
      Score multiplied by weight
      Overall highest total judged to be best product
   More complicated methodologies are available (see

Management by Maxim

   Used to help with infrastructure decisions
    for multi-unit, multi-divisional organizations
       Infrastructure typically takes up about 50% of
        an IT budget
       Creates synergies between units
   Different units may have different
    evaluations for infrastructure
   MbM brings corporate executives, IT
    executives, and business unit managers
    together for planning sessions to determine
    appropriate infrastructure investments.
MbM Process
   Consider Strategic Context
        Identify long-term goals, potential synergies where data sharing
         could help performance, degree of emphasis on inter-unit
   Articulate business maxims
        Short, well-defined goals in areas such as cost, quality, flexibility,
         growth, human resources
   Identify IT maxims
        Statements of IT strategies and goals required to support the
         business maxims
           • Business maxim: “price services at lowest cost”
           • IT maxim: use IT to reduce cost by eliminating duplicated efforts
   Clarify firm’s view of IT infrastructure
        None (independent operations)
        Utility (sharing done to reduce costs)
        Dependent (supports current strategies of business units)
        Enabling (supports long-term goals of business units)
   Specify infrastructure services
        Identify infrastructure services required to achieve business and IT
Option Valuation
   Similar to the idea of option valuation in the securities
   It is possible that the cost of an IT investment exceeds
    its tangible benefits.
   What if the project creates opportunities for other
    projects in the future (like the frequent flier program
    was the unexpected benefit of online airline
    reservation systems)?
       The IT investment has options value that needs to be
         added to the other benefits
       expected value of a IT investment is
         • Size of benefit x probability of its occurrence
         • Eg: 50% chance that investment would lead to $10m in
           new business ($5m benefit)
Balanced Scorecard
(can you tell if you’re winning if you don’t keep
   Developed in the 1990s
   Converts value drivers to series of metrics
       Customer service
       Innovation
       Operational efficiency
       Financial performance
   Companies record and analyze metrics to see if they
    are meeting strategic goals
   Cascades from top of organization downward
   Ultimately, each individual has a personal scorecard
    linked to overall corporate objectives.
IT Scorecard
   Allows for a greater alignment between business objectives
    and IT objectives
   “Customer” is now a client user within company
   Scorecard helps eliminate projects that make little
    contribution to strategic goal (useful in project prioritization)
   Example Metrics from FirstEnergy
        Developing “raving fans” – for IT, that means internal users
        Three metrics
          • Percentage of projects completed on time and on budget.
          • Percentage of projects released to the customer by the
            agreed-upon delivery date.
          • Client satisfaction as indicated by customer surveys
            completed at the end of a project.
        Project managers evaluated based on the metrics
Cost of failure
   Some statistics
      AMR Study (2003) of CRM projects
          • Project failure: 12 percent of CRM projects fail to go live.
          • System implementation: 47 percent of CRM projects go live,
            and the technology aspects of the project are considered a
            success, but business change and adoption fail.
          • Process and system adoption: 25 percent of CRM projects
            succeed in adoption and systems but still cannot quantify a
            specific quantified business benefit.
          • Performance improvement: 16 percent of projects deemed
            success and measurably influence business performance

        Robbins-Gioia Survey (2001) of ERP projects
          • 51% felt ERP implementation was unsuccessful
          • 46% felt organization did not understand how to use the
            system to improve business
What can be done?

   One, One Ten Rule?
       No project should take more than one
        year, cost more than one million
        dollars, and involve more than ten
   Carefully consider build vs. buy
    decisions (see the information
    economics slide)
Managerial Issues
   Constant growth and change in technology (Moore’s
      Necessitates constant monitoring of technology
   Shift from tangible to intangible benefits
   IT not a sure thing
   Use chargeback
      No incentive to control IT costs unless charged; but
        system should not discourage experimentation with
        new technologies
   Risk
      IT projects tend to be risky. Evaluate that risk before
        committing to project
AXA discussion

 What spurred the need for the
  reevaluation of IT projects?
 Comment on what emerges about IT-
  Business alignment before Bateman.
 What were the primary obstacles to
  the plan?
 Do you see any negatives to the
  approach at AXA
