Normal simplification strategy in ScienceReductionism:• Reduce complex systems to ordered systems.• Assume independence and linearity.• Analysis-synthesis, cause-effect, prediction…
Do we need complex systems theory?

Patterns of population growth
Verhulst equation: dX/dt = μX(1-X/A)(X = population size, μ = intrinsic growth rate, A = maximum size,μX = exponential growth, (1-X/A) = rate-limiting)
1. μ = 2.5 => Xn+1 = Xn Stable
2. μ = 3.3 => Xn+2 = Xn
3. μ = 3.5 => Xn+4 = Xn
4. μ = 4.0 => Xn+a ≠ Xn Chaotic

Three phases
• Stable (Xn+1 = Xn).Trivial patterns.
• Complex (Xn+a = Xn).
Non-trivial patterns.• Chaotic (Xn+a ≠ Xn).
No patterns.

Three phases
• Stable (Xn+1 = Xn).Trivial patterns, no adaptation. No learning.
• Complex (Xn+a = Xn).
Non-trivial patterns at many different scales.Order for free, emergence of self-organisation. Learning.
• Chaotic (Xn+a ≠ Xn). No patterns, no stability, no memory. No learning

To use complex system theory in research:Simplification strategies
Science: Reductionism• Assume independence
and linearity• Key variables• Analysis-synthesis
• Cause-effect• Prediction• Control
Complex systems theory: Universality
• Assume same types of processes and structures
• Key processes, e.g. emergence• Actors, their interactions
and the emerging structures• Circular causality• Comprehension• Influence
![Page 12: CDT403 Forskningsmetodik inom naturvetenskap och teknik. Complexity 130926, 13.15-15.00, Zeta](https://reader036.vdocuments.us/reader036/viewer/2022062315/56816305550346895dd381ce/html5/thumbnails/12.jpg)
Three phases, organizations as examples
• Order – the industrial work system with centralized control of details.(Change, development and innovation are side-activities).
• Complexity – a well-functioning and experienced soccer team.
• Chaos – ”In the past 18 months 23 employees at France Telecom have committed suicide, which unions blame on the firm's restructuring program.” 091008 http://www.france24.com/en/20090913-labour-minister-calls-ceo-discuss-suicides-telecom-lombard-darcos

• Bee-hive• Two-cover
• Talk about a married couple from the perspective of complexity. Is it possible that all three phases exists in the same marriage over a short time span?– order (regularities, memory, identity, structures, self-organisation,
integration)
– chaos (unpredictable changes at low level, transformations, autonomy)
– complexity (develops, learns, adapts).
![Page 14: CDT403 Forskningsmetodik inom naturvetenskap och teknik. Complexity 130926, 13.15-15.00, Zeta](https://reader036.vdocuments.us/reader036/viewer/2022062315/56816305550346895dd381ce/html5/thumbnails/14.jpg)
To use complex system theory as an ideal for an organisation
Have both: Order, like regularities, memory and identity. Mechanisms are e.g. emergence of self-organization.
and Chaos, like unpredictable changes at low level and transformations.Mechanisms are e.g. autonomy and external influence.
and, are thus, Complex, adapts, learns and develops.
![Page 15: CDT403 Forskningsmetodik inom naturvetenskap och teknik. Complexity 130926, 13.15-15.00, Zeta](https://reader036.vdocuments.us/reader036/viewer/2022062315/56816305550346895dd381ce/html5/thumbnails/15.jpg)
One requirement to be fulfilled:Sub-actor <–> Actor <–> Meta-actor
• An actor is a wholeness and can only be understood as a wholeness (also true for sub-actors and meta-actors).
• An actor consists of sub-actors and is part of a meta-actor.• An actor is independent, has its own identity, rhythm and
pattern of behavior.• An actor is dependent of a bigger wholeness, the meta-
actor, a slave under structures emerging from interactions (exchange of information/matter/energy ) with other actors of the meta-actor.

Example
• Two ways to understand innovative organization.

Example of convergence: The emergence of culture in a work group
• Values of supervisor.• Talk about goals and
plans.• At least once a
month.• Everyone is included.
