Title: The Second Oldest Profession


1
The Second Oldest Profession
  • "Those who have knowledge, don't predict. Those
    who predict, don't have knowledge. "
  • --Lao Tzu, 6th Century BC Chinese Poet

2
How old is it?
  • I-CHING---- a Chinese Oracle created more than
    4000 years ago.
  • the world's earliest known intuitive
    decision-making system.
  • The most intricate numerically-based oracle ever
    devised
  • Ying vs. Yang? 0 and 1.
  • Oracle of Delphi----the most successful
    prediction business in history

A Look of MIS Prediction Industry
Venture Investors
IT Consultants
IT Managers
IT Strategists
News Media
IT Economists
MIS Researchers
5
The Reign of Error
  • 200 billion
  • in (mostly erroneous) information each year
  • 4,800 million
  • revenues from just two IT consulting companies
    in InformationWeek Top 50
  • Author says these experts whose advice we pay
    handsomely for routinely fail to predict the
    major events that shape our world
  • Somebody says forecasting is the art of saying
    what will happen and then explaining why it
    didn't! "

6
Future Imperfect
Chaos Complexity Theories
Determinism
Situational Bias
  • Chaos Complexity Theories in MIS
  • Decision-making process in information systems
  • Forecasting forecasting? (e.g. stock market)
  • Complex adaptive information systems
  • Semi-Confusing Information systems in changing
    environments

7
Voodoo Economics
  • Governments make decisions based on faulty
    forecasts.
  • Decision makers rely on faulty technology
    forecasts.
  • Dirty (faulty) data can jeopardize your CRM
  • Emerging technology for SCM
  • Collaborative Planning, Forecasting
    Replenishment Technology (CPFR)

8
The Last of the Tooth Fairies
  • Therefore, just because we cannot predict it does
    not mean we can ignore the future.
  • We need to learn how to pluck the gold nuggets of
    advice.
  • "It is far better to foresee even without
    certainty than not to foresee at all. "
  • ------ Henri Poincare in The Foundations of
    Science
  • A pragmatic remark from one of the foundation
    builders of chaos theory

9
Chaos and Complexity
  • "Prediction is very difficult, especially if it's
    about the future."
  • --Nils Bohr, Nobel Laureate in Physics

10
Examples of Chaos and Complexity
  • Weather
  • Severe Storm Warnings
  • Agriculture Planning
  • Economics
  • Government Policy Federal Reserve
  • Elections Candidate Platform
  • Most Investments

11
Forecast Reliability
  • Weather
  • Forecasts with 10-14 day lead time are reasonably
    accurate
  • Distant forecasts impossible to determine
  • Economic
  • On average not much better that chance

12
Naïve Forecasting
  • Assume No Change from Normal Levels
  • Economics
  • Highly volatile areas Naïve better
  • Highly stable Forecasters better
  • Middle Even
  • Weather Follows Seasonal Norms
  • Naïve forecast is close to 90 correct better
    than almanacs

13
Chaotic Weather
  • Chaos Amplifies Mistakes
  • Chaos Has No Starting Point
  • Based on Proven Science
  • Chaos Theory
  • Variability within bounds

14
Chaotic Systems are Predictable
  • Fine Print Accuracy decreases with lead time.

15
Complex Economy
  • No Natural Laws Governing Behaviors
  • Cannot be Dissected into Component Parts
  • Highly Connected with External Forces
  • No Fixed Cycles

16
Complex Systems are NOT Predictable
  • Fine Print Your broker who says it is will be
    discussed later in the presentation

17
MIS Application
  • Naive Forecasting
  • Decent reliability, mush less cost
  • When in doubt, tomorrow will be the same as today
  • Chaotic Systems
  • Explore and understand chaotic problems
  • Fuzzy logic, behavioral analysis
  • Complex Systems
  • Be aware, dont predict
  • Informed Decisions
  • Department policies
  • Legislative procedures

18
Appropriate Models, Methods, and Methodologies
  • "Wall Street indices predicted nine out of the
    last five recessions ! "
  • --Paul A. Samuelson in Newsweek, Science and
    Stocks, 19 Sep. 1966.

19
Background
  • Prediction of stock market has existed since its
    creation (400 years)
  • Payoff is huge
  • Stock market predictions inaccurate
  • Complexity, chaos, speed
  • Fundamentalists vs- technicians
  • Random walk theory, EMH, etc.

20
Example 1 15 minutes of fame
  • Roger Babson Crash of 1929
  • Chicken Little predictions
  • Joseph Granville Granville Market Newsletter
  • Psuedoscientific market analysis
  • Market responded to his news
  • Robert Precther Elliott Wave Theorist Newsletter
  • Downfall came after 1987 due to continued gloom
    and doom predictions
  • Elaine Garzarelli Black Monday (1987)
  • Model simplistic future predictions inaccurate
  • Huge reputation

21
Lessons Learned
  • Appropriately Use models
  • Simplistic models cant account for everything
  • Use informed, but cautious decision making
  • Communication
  • How do you get the word out?
  • News letter, to the media
  • Its all about presentation
  • Prediction is a risky business
  • Being a market guru is a short lived honor
  • Repeat performances are rare
  • Shotgun approach - If you predict a lot you are
    likely to hit it right once
  • Making predictions made the individuals career
    high risk

22
Lessons Applied
  • Appropriately Use models
  • Simplistic models cant account for everything
  • Use informed, but cautious decision making
  • Communication
  • How do you get the word out?
  • Conferences, journals, workshops
  • Can you move your research area?
  • Its all about presentation
  • Prediction is a risky business (especially in
    MIS)
  • Being a guru in an area is a short lived honor
  • Especially if tied to technology
  • Shotgun approach - If you predict a lot you are
    likely to hit it right once
  • Making predictions showcases your credibility
  • Focus on today with possibilities of tomorrow

23
Example 2 - Peter Lynch
  • Managed Fidelitys Magellan Fund 1977-1990
  • Increased 2700 during his management
  • Philosophy
  • I dont believe in predicting markets
  • Takes a systematic approach in areas that arent
    saturated
  • Evaluates a lot of companies

24
Lessons Learned
  • Choose an appropriate methodology
  • He works through bottom up fundamental analysis
    of individual businesses
  • Use various methods to analyze the unknown
    problems
  • Understand the Saturation Principle
  • Stay out of the known zone
  • Boring names disagreeable things
  • Carve your niche
  • Doesnt pay attention to the overall market
  • Hedge your risk (low risk strategy with high
    reward payoff)
  • Have several stocks that are conservative, have a
    few that are risky. The risky ones will make a
    big impact, but are minimized by the conservative
    picks.
  • Work hard
  • The person that turns over the most rocks wins
    the game

25
Lessons Applied
  • Choose an appropriate methodology
  • Establish a concrete sound methodology
    appropriate for your research field
  • Use various methods to analyze the unknown
    problems
  • Understand the Saturation Principle
  • Is the known zone of research saturated? Look at
    unkown or little known problems
  • Boring names disagreeable things might be a
    hotbed for publications
  • Carve your niche
  • Understand the principles of the entire field,
    but focus on a specific area that intrigues you
  • Hedge your risk (low risk strategy with high
    reward payoff)
  • Have several projects that are mainstream
    (conservative), but dabble with some
    revolutionary (high risk) ideas.
  • Work hard
  • The person that turns over the most rocks wins
    the game

26
Science Fact and FictionandThe Futurists
  • The illusion of knowing whats going to happen
    is worse than not knowing
  • James Utterback

27
Background
  • Seek to predict technology trends and their
    impact on society.
  • Seek to predict the future of society in general.

28
Motivation for Technology Forecasting
  • Gain competitive advantages
  • Identify business opportunities
  • Allocate scarce resources appropriately
  • Pure entertainment value (e.g., science fiction
    books)

29
Example 1 Technology Forecasting
  • Japans Ministry of International Trade and
    Industry
  • Long range forecasting
  • Panel of 3000 scientists, engineers and experts
  • Study revealed that 75 of their predictions were
    wrong.

30
Example 2 Technology Forecasting
  • Microsofts reaction to the Internet
  • The Internet? We are not interested in it.
    Bill Gates, 1993
  • Sometimes we do get taken by surprise. For
    example, when the Internet came along, we had it
    as a fifth or sixth priority. Bill Gates, 1998

31
Pros/Cons of Techniques
  • Technological trends take uncertain twists that
    make prediction difficult.
  • 80 of new products never see commercial success.
  • Change can be rapid or take a long time.

32
Pros/Cons of Techniques
  • Social predictions tend to be wrong and are
    subject to situational biases, wishful thinking
    and political agendas.
  • Society is a complex system that evolves and
    cannot be predicted.
  • Sociology is the science with the greatest
    number of methods and the least results
  • Henri Poincaré.

33
Lessons Learned / Application
  • "The herd instinct among forecasters makes sheep
    look like independent thinkers. "
  • Edgar R. Fiedler in The Three Rs of Economic
    Forecasting-Irrational, Irrelevant and Irreverent
    , June 1977.

34
More Lessons Learned / Application
  • Must be critical thinkers and avoid the herd
    mentality.
  • Develop sound theories that can be applied to
    various technologies.
  • Technology is probably not in your theory.
  • Dr. Bob Briggs

35
More Lessons Learned / Application
  • In times of change learners inherit the earth,
    while the learned find themselves beautifully
    equipped to deal with a world that no longer
    exists.
  • Eric Hoffer

36
Check the Unchecked Population
  • The reason why population is hard to predict is
    because when I left my home country the
    population dropped by 10 percent."
  • -- My 250-Pound Neighbor

37
Background
  • Human life expectancy
  • From 25 to 47, took 200,000 years
  • From 47 to 77 (in developed countries), took 100
    years
  • Human population over 5 billion people
  • Questions
  • Can we feed us all? For how long?

38
Is Global Famine Unavoidable?
  • I call the disaster the Time of Famines and I
    say that the Time of Famine will be upon us by
    1975.
  • Famine 1975!, by William and Paul Paddock,
    1967

39
Malthus Prediction
  • Population, when unchecked, increases in a
    geometrical ratio while subsistence increases
    only in an arithmetical ratio. Famine seems the
    be the last, the most dreadful resource of
    nature.

40
Lessons Learned
  • Never ignore major factors
  • Underestimated the productivity of modern
    agriculture, the green revolution
  • Population can be controlled via different ways
  • Birth control

41
Real Challenges to Predict
  • Future births, the unborn
  • Migration is driven by complex circumstances
  • Economic hardship
  • Civil war
  • Governments immigration policies

42
Population Predictability
  • Twenty-year population forecasts could be
    accurate
  • The bigger the target, the better the accuracy

43
Lessons Learned
  • Start with simpler situations
  • Focus on specific area first
  • Solving something is better than solving nothing

The Certainty of Living in an Uncertain World
  • Computers in the future may weigh no more than
    1.5 tons.
  • -Popular Mechanics (1949)

51
Thinking Critically
  • Credibility Assessment
  • Is the forecast based on hard science?
  • How sound are the methods used to make the
    projection?
  • Does the forecaster have credible credentials?
