(3-minute read)At certain points in a matter, a decision is made on the basis of what is known at the time.
The decision appears reasonable in light of the information available.
At that point, the proportionality of the step cannot be fully assessed.
The matter proceeds.
Further information emerges later.
It relates to cost, risk, the strength of a position, or the likely course of the matter.
By the time it becomes visible, the matter has already moved forward.
Commitments have been made.
Work has been undertaken.
A direction has been set.
The new information does not change what has already occurred.
It arrives after the point at which it could have shaped the decision.
Over time, this pattern can repeat.
Information is not absent. It is delayed in its arrival.
Information is most complete after the point at which it is most decisive.
Decisions are therefore made before their full implications are visible.
The decision precedes the information required to fully assess it.
Structural condition
Within a litigation process, information and decision do not arise at the same time.
Information arising from process, investigation, cost development and party response emerges at different times.
Some is available early.
Some becomes available only after steps have been taken.
Information is generated through progression.
It is not fully available at the outset.
At the same time, decisions cannot be deferred indefinitely.
Instructions must be given.
Steps must be taken.
Positions must be adopted.
These decisions are made within an incomplete information environment.
The structure contains a timing separation between decision and information.
Mechanism
Decisions are made under partial information.
Progression generates further information.
That information arrives after direction has been set.
Earlier decisions determine how later information can be used.
Work already performed shapes the conditions under which new information is interpreted.
Expert reports often show this timing problem clearly.
One report may appear to answer the case.
A later report may disagree.
By then, work has already been done, positions may have formed, and
the disagreement may create the next round of questions.
See: When expert reports become their own dispute.
The matter proceeds along a path shaped by earlier decisions.
Changing direction may remain possible.
But it no longer occurs under the same conditions.
It occurs in the presence of prior commitment, established work, and procedural position.
Direction is set before its full implications are visible.
Cost visibility
Cost becomes visible over time.
At early stages, cost is framed in general terms.
As activity occurs, the relationship between work and cost becomes concrete.
Work generates cost.
The scale and nature of that work become visible through its performance.
Cost is not only estimated.
It is revealed through activity.
The full cost implications of a chosen direction are not visible at the point of decision.
They become clearer after that direction has been acted upon.
Cost visibility therefore follows progression rather than preceding it.
Decision control
Decisions occur at defined points.
The information available at those points is partial.
Control is exercised through decisions made under partial information.
A decision-maker may choose between available options.
The consequences of those options are not fully known at the time.
As information develops, it may change how earlier decisions are understood.
The decisions themselves remain fixed.
Their implications become clearer.
Control over direction is exercised sequentially, with each decision informed by the information then available.
Information asymmetry
Information does not become visible at the same time to all participants.
Information is generated within ongoing work and becomes visible once that work reaches a certain point.
Those engaged in that work may observe developments earlier.
Those relying on communicated outputs may observe them later.
Visibility depends on where information is generated, how it is transmitted, and when it becomes capable of assessment.
Risk and cost are therefore not uniformly visible across participants or across time.
Information asymmetry arises from timing as well as distribution.
Stage definition
Stage boundaries influence when information is assessed.
Where stages are broadly defined, information may accumulate within a stage without triggering reassessment.
Where stages are narrower, reassessment may occur more frequently.
In practice, stages are often described at a high level and may evolve as the matter develops.
If information becomes available within a stage but no decision point is engaged, direction may not immediately change.
Progression continues until a further decision point is reached.
Information can therefore develop within stages without altering direction at the time it arises.
System behaviour
A recurring pattern can be observed.
Decisions are made under partial information.
Information expands through activity.
Direction is set before its implications are visible.
Information develops after commitment has formed.
This reflects the interaction between the timing of information generation, the need to progress the matter, and the structure within which decisions are made.
The pattern does not depend on any individual decision or error.
It arises under ordinary conditions.
It reflects the alignment of timing, information and progression within the structure of the process.
End point
By the later stages of a matter, much of the relevant information has become visible.
Cost, risk, and trajectory are more clearly understood.
At that point, the capacity to assess proportionality is higher.
The opportunity to shape direction has narrowed.
Information is most complete after the point at which it is most decisive.
The structure does not prevent information from emerging.
It determines when information emerges relative to when decisions are made.
The cost outcome is therefore not explained by a single decision.
It is explained by the sequence in which information, work and authority developed over time.
