Q

Why do we need to structure problems?

A

Real world problems are ofter messy and complex
You can not think and talk about a problem without ascribing one or more owners to it
Different people have different perspectives about the same system.
Things in real world ofter change over time- They are dynamic.

Q

What are problem structuring methods?

A

A family of methods for supporting decisions for groups of diverse composition within a complex environment to agree a problem focus and make commitments to a series of actions.

Q

To what type of problems are PSMs applied and what characterizes them?

A

Unstructured problems characterized by multiple actors, multiple perspectives, conflicting interests and high levels of uncertainty.

Q

What are the musts for PSMs?

A

Elable alternative perspectives to be considered with each other, be transparent to a range of participants, operate iteratively and allow contingent solutions.

Q

What is the aim of PSMs?

A

Aim is to provide a structure of thinking about what a problem is. PSMs structure can be an end in itself.
PSMs sources came where claims are shared, contested, defended etc.

Q

What are the key characteristics of PSMs?

A

-Techniques to facilitate exploration/ definition of a problem situation
-Group based
Uncovering options
-Enabling group action
-Accepting uncertainty/ alternative scenarios or versions of the situation
-Managing conflict
-Facilitator - Analyst
-Generating construntive improvements

Q

What are the four interacting perspectinves that SODA is based on?

A
  1. Personal construct theory. (capture how the individual’s perspective of the problem in a cognitive map)
  2. Nature of organization.
  3. Nature of consulting practice
  4. Technology and technique.

Q

How is a cognitive map structured?

A

Like a triangle. On the bottom Options (greater delegation is authority). Then consequences (Local representation). Then values in the top (Improve level of service).

Q

What is the structure of a Tear drop?

A

top: Goals or disasterous outcomes
middle: Issues or possible strategies
bottom: More detailed options
Arrows go from Means->End, Option->Desired Outcome
If possible get rid of questions.

Q

How does SSM work?

A

Soft system Methodology. {Real world} Enter situation->Express the problem situation->{System} Formulate root definitions->Build conceptual models->{Real world} Compare models with real world->Define possible changes which are both desirable and feasible. ->Take action to improve the problem situation

Q

What are the pros of PSM?

A
  • Problem structuring
  • Gathering information, generating ideas
  • Retain flexibility in early stages
  • Demonstrate understanding of complexity, diversity and inconsistency
  • Prioritising and simplifying
17
Q

What are the cons of PSM?

A
  • Method development required
  • Methods need to be adapted to the context
  • New skills
  • Ownership
  • Facilitation of group decision making
  • Reproducibility
18
Q

Where is the turning point from Problem structuring to model structuring?

A

When it becomes clear to the decision analyst which type of decision-aiding model will be more adequate for value analysis in the specific context.

19
Q

What are two bacis model-structuring strategies?

A

Bottom-up (alternative focused thinking)

Top-Down (Value focused

20
Q

How does bottom-up method of model structuring work?

A

Bottom-up (alternative focused thinking)

  • Define a set of options
  • Analyse the characteristics of these options (find the relevant ones)
  • Find out the key objectives
21
Q

How does Top-down work?

A

Value-focused thinking:

  • Define objectives
  • Seperate means from ends objectives
  • Indentify fundamental objectives
  • Find options as means to achieve the objectives.
22
Q

How do you identify the evaluation criteria?

A
  • Start model structuring bu a broad discussion of key issues.
  • Values emerge during the discussion either as objectives or characteristics relevant for the analysis.
  • They should be well defined and percieved by all the key players to avoid ambiguity and misunderstanding.
  • Seperate means-objectives from end objectives.
  • Structure them in a criteria value tree
23
Q

What are the desirable properties for a good set of fundamental objectives?

A
  • Consensual, and therefore
    -exhaustive, but also
    -concise and non-redundant, and
    -decomposable, which requires:
    *each criterion is measurable and operational
    *the criteria are mutually perferential independent
    In the context in which options are to be evaluated.
24
Q

What is cardinal independence?

A

Additive aggregation requires that such an isolate evaluation axis, that is mutual cardinal independence to hold (ordinal independence is not enough)

25
Q

How do you measure the extent to which evaluation criteria can be achieved?

A

Associate with each criterion a descriptor of performance, that is: A qualitative or quantitative measure of the extent to which the criterion can be satisfied.
