The Morals of the Tale
The guy who gets you into the
is not necessarily your enemy.
The guy who gets you out of the
is not necessarily your friend.
When you’re up to your neck in
don’t sing about it.

Flaws Generate Risks of Error
Error of execution (Performance Risk)inability to sustain the performance of the capabilities one requires to provide the service.
Error of planning (Composition Risk)inability to ensure the validity of one’s approach to composing capabilities in order to deliver the service.
Error of intention (Implementation Risk)inability to guarantee that the service will satisfy the client’s need when deployed in her context-of-use.

Asymmetric DemandSymmetric Demand
the market is defined in terms of what the supplier can provide supplier assumes that demand is independent of clients’ contexts-of-use.
strategic stance is positional, client is a customer,service is a commodity, power is held at the centre,implementation risk is ignored
Has successfully provided a vast variety of commoditised, cheap, globally accessible, networked services, but leads clients to expect services specific to their context-of-use.
Asymmetric demanddemand is defined in relation to the client’s context-of-use
forces the supplier toadopt relational strategies,take power to the edge, where multiple contexts-of-use are authorisedand make the enterprises agile enough to satisfy the variety of demand.

The Existential Articulationontology of supply
a relational model of the actor's knowledge of how her world behavesin terms of:
processes: closed systems that, as material causes, change (public) states-of-affairs
events: states-of-affairs that are observed to pertain after a process
coordinations: collections of processes (and/or coordinations, recursively) that are observed to occur together in some purposeful way.

The Deontic Articulation
outcomes: observable states-of-affairs;
transformations: mechanisms that alter outcomes; and
synchronisations: collections of outcomes (and/or synchronisations, recursively) that may be made to occur together.

Existential DeonticThe existential and deontic articulations are composed by asserting mappings that implicate existential events in deontic outcomes.
This composite articulation denotesthe repertoire of behaviour paths known to the actor —
the space in which she, as efficient cause, can construct and execute plans.
Which plans she chooses will depend onhow she values their implicated behaviour paths and outcomes.

The Referential Articulationontology of demand
a relational model of the actor's ontology of herself as an anticipatory systemin terms of
drivers, which attribute value to the actor's experience (by being, more or less, 'satisfied' by paths-of-behaviour);
demand situations, states-of-affairs whose coming to pass is anticipated to be of value with respect to certain drivers; and
value ladders, in which the experience of collections (recursively) of certain demand situations is anticipated to be of value with respect to certain other drivers.
