Loose Coupling, Tight Coupling and Dialectic Coupling in Risk

Loose and tight coupling are metaphors Weick uses to explain ways of organising.

Interestingly, it depends on context to whether these metaphors are useful. In mechanics for example, a loose fitting is generally troublesome. If the nut is loose, we need to tighten it up. Then again being ‘up-tight’ in a relationship can be detrimental and stressful.

Understanding the power of metaphor is foundational to understanding Prof. K. E. Weick. Weick is Poetic in much of his writing and his use of figurative language is critical in understanding what he means about organising.

The idea of tight coupling is also linked to what Amalberti and Taleb describe as ‘hyper-safety’. This is when one tries to make every aspect of a system so tight and controlled, that all attributes of: flexibility, bricolage, improvisation, ecological meaning and adaptability are eliminated. According to Weick, the by-products of tightly-coupled systems is a loss of these attributes. He states (1979):

To summarize, when it is asserted that selection is partially constrained by

enactment, the following is implied:

1. Enactment (saying) and selection (seeing) both generate plausible inter-pretations of equivocality, but the interpretations imposed during selection are fuller, more varied, and remove more equivocality.

2. In the case of organizations, ecological changes favor adaptive actions that are flexible, loosely structured, and improvised.

3. Loosely structured enactments are difficult to label and may be destroyed when people treat them as more orderly, unified, and integrated than they actually are.

The loss of these important attributes creates new risks that remain hidden, suppressed and obscure.

It is also important in Weick to realise that his thinking is not binary as I have often seen in safety commentary on Weick. If you understand Weick’s philosophy you will know that he doesn’t think in binary ways. His thinking is much more Poetic and dialectic.

Loosely and tightly coupled systems need to be considered on a continuum. This is illustrated using the following venn diagram and SPoR concepts.

Weick (1979) states:

Our concern about the difficulty of preserving the basic equivocality of loosely coupled enactments is not idle, because one of the most common perceptual errors is that people overestimate the amount of unity, orderliness, and clarity that is present in an input. This tendency has been known for a long time and is preserved in Bacon’s Idols of the Tribe, the first of which reads: “The human understanding, from its peculiar nature, easily supposes a greater degree of order and equality in things than it really finds” (cited in Campbell 1959, p. 5).

Understanding this continuum is critical in understanding how Weick explains systems and organising. Using another metaphor, it’s a juggling act.

So, as we see efforts in safety to get tighter control through: linear control (James Reason, FRAM), zero ideology, hierarchy of control, Bradley Curve and Heinrich, we see efforts that work against the critical attributes of flexibility, bricolage, improvisation, ecological meaning and adaptability are eliminated.
