The Change Process

Sensing the need for change

Exploring possible change strategies

Deciding change strategies

Planning & Implementing change

Consolidating within organisation

Become common practice in many organisations

Change Process

Strategic Models

why do models fail
Why do models fail?
  • Developed after decision made (ex post justification)
  • Internal vs. external validity
  • Multiple, ill-defined objectives
  • Model as solution to problem –jumping to conclusions
approaches to planning
Approaches to Planning
  • Rationalists - find optimum strategy
    • Planning
    • Forecasts
  • Evolutionists - strategies emerge.
    • Complex world
    • Political processes
    • All rational processes irrelevant
  • Processualists - intermediate.
    • Future uncertain, but not entirely unpredictable
    • Scenario planning
    • Computer simulations: explore options
types of models
Types of Models

Financial

Regressions

Optimisation

Forecasting

‘Soft’

Hard

Exploratory

Flight simulators

Business games

Conceptual models

exploratory models
Exploratory Models
  • Conceptual models
    • clarify concepts/ relationships
    • common language
    • represent (shared) mental models
  • Simulations
    • Quantify the conceptual models
    • Reveal importance of different processes
    • Outcomes

Strategy
decision making in a complex world non rational but not irrational
Decision-making in a complex world: non-rational but not irrational
  • Rational decision-making:
    • Rationality, bounded rationality:
    • Optimisation, sufficing
  • Real decision-making
    • Role of emotion
    • Business strategy
      • Planning
      • Vision, ethics, culture
    • Experience: ‘rule of thumb’
    • Habit/ tradition: learned behaviour
    • ‘Gut feeling’
  • Why OR?
    • Improve decision-making
    • Need both soft and hard

Simulations

recognised strategic issue

knowledge base

mental models

assumptions

maps & diagrams

executive debate & dialogue

dynamic simulation

models

strategy for change

procedural intelligence
Setting Boundaries

Choice of Frames

Problem Structuring(within frame)

Interpreting Structure

Assigning referents

Defining Vision; defining problem

Analysis (SSM, SODA, CM, scenarios planning)

Conceptual models; Influence diagrams

Exploration of conceptual model - alternative scripts. Simulations

Data (market surveys etc.)

Procedural intelligence
why simulations cognitive problems
Why Simulations?: Cognitive problems

Issues

  • Most people deal with only 3-4 variables at a time, and only through 1-2 time steps (de Guess).
  • Effect of interdependence
  • Effect of delay

Simplifying assumptions

  • Single cause/ effect
  • No delays
  • Systems simple/ independent

Need simulations

  • Quantitative results
  • Reveal importance of different processes
  • Outcomes
exploring the future scenarios

models a process not an end
Models: a Process not an End

What is the question?

Analysis

Customer Workshop

Conceptual model

Modelling team

Construct Simulation

Investigate ‘What-ifs’

benefitting from the model
Benefitting from the Model
  • Identify the problem
  • Build the model with the ‘customer’
  • Involve as many parties as possible
  • Diagrams help identify conflicting views
  • Where data ‘missing’ get expert advice
    • base case
  • Flight simulator: test by doing ‘what-ifs’
hard or soft does it matter yes and no
Hard or soft: does it matter? Yes and no.
  • Armed camps or Complementary
  • Different purposes/roles: procedural levels
  • Soft comes first?
  • Better seen as a spectrum?
  • What are the bridges:
    • Model building seen as a process, not an end
    • Exploratory models
    • Complex (adaptive) systems and complexity theory
    • People: intermediaries
    • Evidence-based policy-making?
  • What is better decision-making?
    • What is OR for?
    • Outcomes & Values
    • Utilitarianism vs conviction
