Problems, problems
  • Problem why do so many government policies fail?
  • Common reasons failure to understand the task,
    unhelpful misperceptions, assumptions and
    politics, policy conflicts, resulting in
    incoherent priorities unachievable missions.
  • Examples
  • Why do countries get poorer when aid flows
    increase?
  • Why do we negotiate for aid programs that damage
    our economy?
  • Why do measures to protect jobs increase
    unemployment?
  • Why do government agencies undermine each other?
  • Why cant we solve the drug problem?

Example War
  • The nature of war has changed
  • Wars were formerly between nations the majority
    of conflicts today involve civil
    wars/insurgencies. War today is more likely to
    involve infiltration rather than invasion.
  • Wars are increasingly asymmetrical, between
    security forces and unconventional irregular
    forces.
  • In traditional warfare, most of the fatalities
    were soldiers. Today, most of the casualties are
    civilians.
  • The nature of war has changed fundamentally more
    significant changes are expected over the next
    10-20 years.
  • The way in which the issues are perceived by the
    general public (taxpayers, voters, recruits) has
    not kept pace. So there is an increasing
    disconnect.
  • Even more important, the way in which the issues
    are perceived by the professionals has not kept
    pace

Wargame exposed gaping hole in Pentagon strategy
Julian Borger, The Guardian Tuesday September 25,
2001
  • When terror came out of a clear blue sky on
    September 11, some of the Pentagon's top brass
    were given a jolting reminder of a wargame they
    played in 1997. In the game, the US was pitted
    against a zealous, decentralised terror
    organisation very like al-Qaida, and the US lost.
    Each time the US forces thought they had scored a
    blow against the terror organisation, it would
    regenerate itself to strike on another front. It
    emerged from the campaign more or less unscathed.
  • That was four years ago, but some of the military
    strategists who organized the game believe the
    Pentagon failed to learn the lessons from the
    wargame, and said yesterday that the US military
    was still a long way from readiness to fight the
    adversary it now faced.

5
The Pentagon still fighting the wrong war
  • According to Doug Johnson, a strategic studies
    professor involved in the 1997 exercise, the army
    lost because it didn't want to play that game.
    The army brass, Dr Johnson said, were intent on
    fighting a variation of a war against large tank
    armies on the central plains of somewhere. At
    one point, the Pentagon officers involved became
    so frustrated with their elusive opponents that
    they asked for the game organizers to have a
    friendly government's armoured battalion defect
    to the other side. They did it to give someone
    to blast, Dr Johnson said. Everyone went away
    feeling viscerally satisfied.
  • As a result, they missed the point. The terror
    organisation still had most of its cells in
    place, and a functioning financial network.
  • Within the contours of that particular game, the
    American forces and their allies simply weren't
    configured to deal with an enemy like the one we
    created, said Steven Metz, head of the Army War
    College's regional strategy and planning
    department.

Lessons?
  • This illustrates three points in policy analysis
  • Distinguish between perception and reality.
  • Be wary of the Conventional Wisdom of the
    Dominant Group (COWDUNG), as a failure on a core
    assumption is likely to be fatal.
  • The importance of seeing both the current
    position and the underlying context or trend.

7
Making better policy
  • Question how can we increase the chances of
    success?
  • Answer a more systematic approach, to help us
  • Control for preconceived ideas and assumptions
  • Check the facts, get the problem into focus
  • Identify our options
  • For each option, identify costs and trade-offs
  • Agree our priorities
  • Build the necessary consensus about the way
    forward
  • Implement!
  • Monitor, change tactics if required, stay focused
    on the goal

8
Bardachs Eightfold Path lists the main steps
  1. Define the problem. What are we trying to
    achieve?
  2. Assemble the evidence. What are the facts?
  3. Construct policy alternatives. What can we do?
  4. Select the criteria. How are we going to decide
    which is the best policy?
  5. Project the outcomes of each policy option. What
    would happen if we tried this?
  6. Assess the trade-offs. How much will this cost?
    What are the chances of success? Could this
    tactic create some other problem?
  7. Decide. What are you going to recommend to the
    Minister?
  8. Present. Set out the problem, your analysis and
    your recommendation.

9
3) Constructing policy alternatives
  • Must be evidence-based (from stage 2).
  • Take into account a range of expert advice and
    stakeholder views.
  • Represent the main bodies of opinion.
  • Help to bring issues into focus (usually achieved
    by making sure that alternatives are sufficiently
    diverse).
  • Example 1 Swedish defence policy
  • Example 2 Go Big, Go Long, Go Home.

10
4) Select the criteria
  • What is important? Is it
  • Results at any cost
  • Results, provided that the process is not too
    expensive
  • Results, provided that they can be achieved
    without upsetting anyone with a lot of political
    influence
  • Not to change anything, but to make it look as
    though we are taking the problem seriously
  • So does the proposed solution have to be
  • The solution that we think has the best chance of
    success?
  • The cheapest/quickest/most legal solution
    available?
  • The most politically-acceptable way forward?
  • The one that will make us look good?

11
5) Project outcomes for each option
  • This is most technically difficult step, because
  • We have to be realistic, rather than optimistic
    or pessimistic
  • We have to resolve very significant uncertainty
    into a clear decision, on which much will depend.
  • It is about the future, NOT the present
  • Key questions what would happen if we did this?
  • Have we tried anything like this before? What
    happened that time? Why?
  • Has anyone else tried anything like this? What
    happened to them? Were the conditions similar?
  • How will people react if we do this? How will the
    community respond? Will there be political
    problems? How will the different interest groups
    react? Could there be legal challenges?

12
Estimating impacts and costs
  • Example the cost of crime control in Jamaica
  • For J180m we can reduce homicides by 5.
  • If 5 80 homicides, cost of reduction
    2.25m/homicide.
  • What are the chances of success? 90? 50? 10?
    1?
  • What are the risks of unwanted side effects?
  • How does this compare against e.g. investment in
    schools?
  • Bearing in mind that
  • Job security increases unemployment
  • Safer drivers take more risks
  • Free zones encourage relocation, not job-creation

13
6) Dealing with trade-offs
  • One option is clearly the best (rare)
  • Each option has a different combination of costs
    and benefits (the usual situation)

Option Cost Chance of success Risks
A Medium High High
B Low Low Medium
C High Medium Low
14
Aggregated vs disaggregated decision-making
  • Aggregated resolve everything into a single
    numeraire (usually cash).
  • Disaggregated use matrices, maps and diagrams to
    keep more dimensions in view.
  • There are pros and cons for each approach.

15
Aggregated
Low 0-3 Option make negative Medium
4-6 factors (e.g. cost, risk) High 7-10 negative
numbers.
Option Factor A - cost Factor B prospects Weighting 2 Factor C - risks Total
Plan A (Medium) -5 (High) 8 16 (High) -8 3
Plan B (Low) -2 (Low) 3 6 (Medium) -4 0
Plan C (High) -7 (Medium) 6 12 (Low) -3 2

16
Probability/impact matrix
  • The conclusions from a policy exercise usually
    have to be absorbed into a government (or
    business) agenda that is already crowded. It is
    important to have greater clarity about future
    problems and potential solutions, but that does
    not remove the need to make the large number of
    day-to-day decisions involved in managing a
    Ministry or government agency.
  • So it is important to have priorities for action.
  • A probability impact matrix is a way of
    organizing these priorities. It is similar to the
    triage used by military doctors when dealing with
    incoming casualties.

17

18
High impact, low probability (we thought)
  • It is sensible to allocate most time and
    resources to high impact, high probability
    events, but it is also important to monitor high
    impact, low probability events
  • The US Federal Emergency Management Agency knew
    that New Orleans was potentially vulnerable to a
    hurricane, and had identified this as one of the
    three worst disasters that could befall the
    United States. This was, however, seen by the
    administration as a low probability event.
  • On the 28th29th August 2005, Hurricane Katrina
    resulted in a 28-foot storm surge as well as
    torrential rain, the latter raised the height of
    Lake Pontchartrain by 7.6 feet, and the
    combination overwhelmed the levees that protected
    the city of New Orleans. About 80 of the city,
    which is on average about 6 feet below sea level,
    was then flooded.

  • Are you convinced?
  • Are your colleagues convinced?
  • Are the external experts, independent advisors,
    stakeholders convinced?

Project management tools
  • There are a range of useful tools, including
  • Project cycle management
  • LogFrame planning
  • Critical Path Analysis
  • PERT analysis
  • Gantt charts
  • These can help to
  • Identify the important sub-tasks.
  • Identify the dependencies between sub-tasks.
  • Organize the dependent sub-tasks into the
    appropriate sequence.
  • Identify potential vulnerabilities.
  • Identify the minimum time required to complete a
    project.
  • Identify where resources can be optimally
    allocated.

22
Project cycle management (1)
  • Most projects can be divided into a 6 phase
    project cycle
  • Defining the theme. This is the choice of area,
    usually a list of key problems that require a
    policy intervention (typically scoring high on
    risk, public concern, or assessed chances of
    success).
  • Project identification. This is the initial
    formulation of ideas for the actual project,
    including objectives, expected results and a list
    of the actions to be taken. The goal at this
    stage is to work out whether it is worth going
    ahead with a feasibility/pilot study. If the
    answer is yes, then the next step is usually to
    draw up the terms of reference and undertake the
    study.
  • Formulation. This involves looking at the results
    of the feasibility or pilot study and specifying
    the project itself. Objectives, expected results
    and a list of the actions to be taken must now be
    set down in precise detail. These must then be
    checked back against the theme defined earlier.
    If the project is going to require external
    funding, it is at this stage that you decide
    whether or not to draw up a bid for funds.

23
Project cycle management (2)
  • Financing. For those projects that require
    external funding this stage involves drafting
    the funding proposal, bidding for and securing
    funds, negotiating and signing the contracts.
  • Implementation. This involves executing the
    project, monitoring progress and achieving the
    results.
  • Evaluation. This stage involves analyzing the
    results and assessing the impact of the project
    both during and after its implementation. The
    goal is to identify any lessons to be learnt that
    could help with other projects, both now and in
    the future. Projects that require external
    funding are often phased, with the release of
    funding for each stage conditional on the
    completion of a full evaluation of the previous
    stage.

24
LogFrame risk reduction
  • What is LogFrame?
  • Logical Framework (LogFrame) planning involves
    analyzing and setting out, in a systematic and
    logical way, the objectives of a project and any
    causal relationships between the objectives of a
    project.
  • It involves working towards these objectives,
    monitoring progress and checking that the
    objectives have been achieved. It also involves
    establishing the extent to which the success of
    the project depends on factors that cannot be
    controlled, and the extent to which the project
    is therefore exposed to risk.
  • How LogFrame help?
  • By helping us to think methodically and identify
    all the factors essential to the success of the
    project.
  • By encouraging us to check and test our ideas,
    monitor progress, identify problems and take
    remedial action while there is still time to save
    the project.

Critical Path Analysis (1)
  • Critical Path Analysis and the related PERT model
    were developed in the 1950s to manage military
    projects, but are now more generally used to
    manage any particularly large, complex project.
    Another related tool, the Gantt chart, was
    developed three decades earlier. These tools
    involve listing all the sub-tasks in a project,
    then organizing them into two groups
  • Sequential the first group consists of those
    tasks that have to be completed in sequence,
    because each stage depends on the one before.
    When building a factory, for example, the
    foundation must be finished before the
    load-bearing walls go up, and the walls must be
    ready before the roof can be fitted.
  • Parallel the second group consists of those
    tasks that do not depend on the completion of
    other tasks. These can therefore be completed in
    parallel, i.e. at the same time as other tasks.
    In the same factory building project, for
    example, the contractor might decide that the
    tarmac for the car park can be laid at any time
    this does not depend on progress with the
    foundations, walls or floors of the main building.

27
Critical Path Analysis (2)
  • The tasks are then represented in a diagram which
    shows the flow of events. The critical path is
    the line through the series of sequential events.
    This shows the minimum amount of time needed to
    complete the project as a whole. This also shows
    where the project might be vulnerable, because
    any failure on the critical path will always have
    implications for either the timetable (the
    completion will be delayed) or the budget (we
    will have to hire more people to get this phase
    finished on schedule). The key points along the
    critical path usually serve as the decision
    points for the project.
  • This process shows where additional resources
    would have the most effect. Additional
    expenditure on a critical path event can shorten
    the amount of time required, and help to get a
    late project back on schedule. Hiring more
    bricklayers, for example, can help to get the
    walls finished earlier, thus making it possible
    to get the roof fitted. Additional expenditure on
    a parallel task, however, such as bringing in
    another roller to level the car park, will not
    help to shorten the timetable. This reveals how
    resources can be reallocated from parallel tasks
    to sequential tasks in order to speed up a
    project. This sort of tactic is sometimes
    referred to as a crash action programme.

28
Program Evaluation Review Technique (PERT)
  • PERT is a form of Critical Path Analysis which
    also corrects for the fact that most people
    underestimate how long each task will take, while
    some people will overestimate the time required
    in order to inflate their bonuses. PERT is
    calculated by estimating the shortest possible
    time each task will take, the longest likely time
    each task could take, and the most likely amount
    of time that each task will actually take. In
    effect, PERT uses a band of values, with a top
    and bottom end and a most likely value, as
    opposed to a single value.
  • This band is then resolved into a single value,
    usually in the following formula shortest time
    4 the most likely time the longest time/6. So
    if, for example, the shortest time was 2 days,
    the longest time 8 days, and the most likely time
    4 days, that would give 2 (44) 8 26/6
    4.3 days.
  • This final value is then used instead of the
    shortest time value of 2 days or the longest
    value of 8 days, thus correcting for
    over-optimism or under-bidding.

29
Visual tools
  • Critical path, PERT and Gantt charts (Gantt
    charts were developed by Henry Gantt in 1917) are
    usually shown as horizontal bar charts that show
    the important tasks over time.
  • These are useful visual tools for keeping track
    of projects.

30
How to make Critical Path, PERT or Gantt charts
  1. Make a list of all tasks/activities involved in
    the project.
  2. Put them into sequential order.
  3. Estimate the time it will take to complete each
    task and put the time next to that task on the
    list.
  4. Readjust the sequence of tasks as necessary.
  5. Determine who is responsible for each task on the
    list and put their name next to that task.
  6. Label the chart across the top by day/week/month.
  7. Label the chart along the left side with all the
    tasks.
  8. Draw horizontal bars for each task beginning at
    the start date for that task and ending with the
    completion date for that task.

5) Project outcomes for each option
  • This is most technically difficult step, because
  • We have to be realistic, rather than optimistic
    or pessimistic
  • We have to resolve very significant uncertainty
    into a clear decision, on which much will depend.
  • It is about the future, NOT the present

So how do we plan for the future?
33
The problem with forecasts
  • Sophisticated, highly-paid economists have
    successfully predicted seven of the last three
    global recessions (various sources).
  • Never make forecasts especially about the
    future
  • - Sam Goldwyn

34
Why do forecasts fail?
  • 1) Trends change. We start from the current
    position, identify and extrapolate trends. We
    tend to assume that these will continue but
    eventually they dont. Competition intensifies,
    markets saturate and preferences change.
  • 2) Parameters change. Market trends are shaped by
    underlying social and economic factors e.g.
    demographics, productivity growth and
    technological development. These structural
    factors usually change slowly but external
    shocks or new disruptive technologies can
    represent discontinuities (or tipping points)
    that precipitate more rapid change and
    restructure markets.
  • Trend change is (in principle) predictable.but
    it is difficult to anticipate discontinuities.

35
Can we do better?
  • Conventional forecasting results become less
    reliable at times of significant, rapid and
    pervasive change
  • We are living in an unprecedented era of
    accelerating technological, economic and social
    change, driven by
  • New technologies, such as informatics,
    biotechnology, and nanotechnology
  • Global trade liberalisation, which could increase
    contestable world output from 20 of the total to
    80 of the total by 2030
  • The re-drawing of world geopolitical parameters
  • Changing pattern of resource demand,
    environmental impacts
  • Are there more reliable decision/planning tools
    for times of change?

36
What is foresighting?
  • Foresighting is a tool used
  • to inform decision-making
  • to help people anticipate future opportunities
    and avoid problems
  • Foresighting involves
  • envisioning a range of possible future scenarios,
  • testing these rigorously, then -
  • back-casting to present day, and mapping out the
    steps needed to achieve the preferred
    scenario/avoid the worst-case scenario.
  • The foresight process itself is important,
    because
  • it clarifies and challenges assumptions
  • it encourages shared visions and flexible
    thinking
  • it creates new knowledge networks

37
Changing parameters climate change
38
Earth's temperature is dangerously high - NASA
  • Researchers at Nasa's Goddard Institute for
    Space Studies said that Earth's temperature was
    now reaching its highest level in a million
    years. Dr James Hansen, who led the study, said
    further global warming of just 1C could lead to
    big changes to the planet. If warming is kept
    less than that, effects of global warming may be
    relatively manageable, he said. But if further
    global warming reaches 2 or 3C, the Earth may
    become a different planet to the one we know
    now. The last time it was that warm was in the
    middle Pliocene, about 3m years ago, when sea
    level was about 25 meters (80 feet) higher than
    today.
  • The study showed that there was already a threat
    of more extreme weather like the strong El Niños
    in 1983 and 1998, when many countries around the
    world had devastating floods and tornadoes.

Is this a solvable problem?
Previous environmental treaties have had partial
success The Montreal Protocol, which limits CFC
emissions. The Basle Convention, which controls
trans-boundary shipments of hazardous waste. But
these are relatively solvable problems compared
to energy use carbon emissions derive from the
use of our primary energy sources.
43
Kyoto redundant before ratified
  • The US, the largest source of carbon emissions,
    has not ratified the protocol, partly because it
    imposes no limits on the gases produced by
    developing countries.
  • China, which is now the worlds biggest consumer
    of coal and second biggest consumer of oil, emits
    almost as much carbon as the 25 members of the EU
    combined, and will shortly overtake them to
    become the worlds second largest source of
    carbon emissions, is exempt.
  • As a result of these non-ratifications and
    exemptions, UN projections indicate that the
    treaty will reduce the currently projected rise
    in average surface temperature of 1.4 to 5.8C by
    2100 by just 0.1.

44
Methane release
- potential disaster?
  • There are naturally-occurring greenhouse gases,
    mostly methane, trapped in ice-like structures
    called clathrates. Most of these are trapped in
    cold sediments and Arctic tundra.
  • There is 400 gigatons of methane currently
    trapped in frozen arctic tundra. If the
    temperature gets too high, and the tundra
    defrosts, this methane will be released. Methane
    is gt20 times more efficient than CO² as a
    greenhouse gas, so this could cause runaway
    climate change.
  • Similar events have happened before. The largest
    previous release of methane happened at the
    Permian-Triassic boundary event, about 250
    million years ago, when 95 of extant species
    were destroyed. It took 20 - 30 million years for
    rudimentary coral reefs to re-establish and
    forests to re-grow in some areas it took gt100
    million years for ecosystems to reach similar
    levels of diversity.

A Stern warning (part 1)
  • Key points in the report written by Sir Nicholas
    Stern for the UK government, published on Monday
    30th October
  • CO² and temperature rise
  • Carbon emissions have raised global temperatures
    by 0.5C.
  • With BAU, there is gt75 chance that global
    temperatures will rise by 2-3C over the next 50
    years. There is a 50 chance that global
    temperatures could rise by 5C.
  • Environmental impact
  • Melting glaciers will increase flood risk, then
    drought.
  • Crop yields will decline, particularly in Africa.
  • Rising sea levels could displace 200 million
    people.
  • Up to 40 of species could become extinct.
  • There will be more frequent extreme weather
    patterns.

47
A Stern warning (part 2)
  • Economic impact
  • A rise of 2-3C could reduce global GDP by 3.
  • A rise of 5C could cost up to 10 of global GDP.
    The poorest countries would lose
    disproportionately more.
  • Worst case scenario the global economy could
    shrink by 20 - permanently.
  • Cost of remedial action
  • Controlling this risk would require stabilizing
    emissions within the next 20 years then reducing
    by 1-3 pa. The transition to a low-carbon
    economy would cost 1 of GDP, mostly one-off
    expenditure (e.g. investment in low-carbon
    technologies).
  • Conclusion
  • A one-off investment of 1 could avert a
    permanent reduction in annual income of 5-20.

Surging demand
  • Transport still only accounts for 14 global
    emissions, less than power generation and
    land-use.
  • However, air travel is the most rapidly-growing
    source of carbon emissions.
  • This growth in the demand for global transport
    (driven by falling prices and increasing demand)
    is now seen as one of the most intractable
    problems in slowing the rate of climate change.

51
Growth in air travel
  • Air traffic has been expanding at nearly 250 of
    average economic growth rates since 1959.
  • The current UK Government's Aviation White Paper
    notes that aviation has increased fivefold over
    the last 30 years, and predicts that UK passenger
    numbers will more than double from 180 million to
    475 million over the next 25 years.

52
Carbon-intensive activity
  • Air travel is not only the most rapidly-growing
    source of carbon emissions, it is also very
    energy-intensive. For example, a Boeing 747 burns
    about 5 gallons per mile, so a London to New York
    flight (3,471 miles) requires some 17,355
    gallons.
  • Air travel relies on carbon-based fuel, so it is
    a carbon-intensive activity more so than other
    forms of transport. For example, a short flight
    (under 500km, e.g. London to Amsterdam) generates
    0.17kg of carbon/passenger/kilometre, compared
    with 0.14 kg/km by car, 0.052 kg/km for rail and
    0.047 kg/km by ship. So flying produces over
    three times more carbon/kilometre than rail, and
    over three-and-a-half times more than travelling
    by ship.
  • As a result, a return flight between the UK and
    Australia produces about 3 tonnes of carbon per
    person (for comparison, an average car emits
    about 6 tonnes of carbon per annum).

53
Aggregate carbon emissions
  • The world fleet now consists of about 16,000
    commercial jet aircraft. These generate over 600m
    tonnes of CO² per year.
  • This means that aviation generates now nearly as
    much CO² as all human activities in Africa.

54
Consuming the carbon allowance
  • In September 2005 the UK's Tyndall Centre for
    Climate Change calculated that all householders,
    motorists and businesses in the UK would have to
    reduce their CO² emissions to zero if the
    aviation industry was to be incorporated into the
    UK Government climate change targets for 2050.
  • In other words, the entire UK economy would have
    to emit no carbon at all, because the airline
    industry would be emitting so much that it would
    consume the UKs entire carbon allowance. The
    same equation is true of most other EU member
    states. This is clearly impossible.

55
Technological options?
  • There have been significant improvements in
    aircraft and engine technology. The new
    generation of planes (like the Airbus A380 and
    the Boeing 7E7) are partly made of carbon
    composites, rather than metal, therefore offer
    significantly better fuel efficiency and reduced
    emissions per passenger.
  • But the IPCC point out that these gains will be
    erased by the projected growth in demand, which
    means that total fuel consumption and emissions
    of e.g. carbon dioxide, water vapour, nitric
    oxide, nitrogen dioxide and sulphur dioxide will
    continue to rise.
  • It is not (yet) possible to operate aircraft on
    biofuels (but do we have enough land anyway?)

56
Scarcity is dynamic
  • Scarcity reflects four main factors
  • Total physical quantity in available
    form/location.
  • Technology required to find, extract, process and
    transport the resource.
  • Pattern of demand/use (also partly determined by
    available technology).
  • Economics (anticipated) demand, supply,
    competition, alternatives substitutes.
  • These four factors determine energy
    resource-use efficiency.
  • So calculations of sustainability must take into
    account a number of factors, including (a) total
    stock, location and accessibility (b) available
    technology, (c) economics (d) market and
    technological trends, (e) development trends (f)
    demand growth and so on.

57
Solutions
  1. Faster technological advance, including both
    incremental gains and more radical substitutions.
  2. Faster progress in offset (flanking)
    technologies.
  3. Demand-rationing, via price.
  4. Command-and-control, via regulation.
  5. Disaster preparedness, zoning, planning,
    exercises and mitigation.

58
Conclusions
  • We need a robust process for making, implementing
    and monitoring policy.
  • This has to be based on strategic/scenario
    planning and risk mapping.
  • We need to search for the optimal (attainable,
    achievable or affordable) solution this might
    lie in another discipline or jurisdiction.
