(3-minute read)At some point in a dispute, costs become difficult to predict.
Early on, there is usually a sense that the matter can be scoped. There is a claim, a response, and a sequence of expected steps. Engagement terms are set. Estimates may be provided. The process appears structured.
Over time, that sense of structure can become harder to maintain.
This shift reflects how the process is structured to unfold in practice.
Costs emerge as the matter progresses through stages that are not fully defined in advance. Information about those stages often arrives incrementally, and sometimes only after work has already begun.
Cost is not revealed at a single point. It is generated and becomes visible progressively.
This is a recurring structural pattern. It arises across different types of disputes and forums. It does not depend on the capability or conduct of any individual participant.
This pattern can be understood as a function of how cost becomes visible over time within the process.
When predictability begins to shift
At the outset, visibility is typically local rather than process-wide. Costs are described by reference to immediate steps or early phases, not the entire path the matter may take.
That path remains contingent. It includes both efforts to resolve the matter and preparation for possible adjudication. These may proceed at the same time.
Because the full path cannot be defined in advance, neither is the full cost structure.
At any point in time, visibility is local. The overall trajectory remains uncertain.
How cost information is generated
In practice, the matter evolves through stages that become clearer only as it progresses. Each stage brings its own work, timing, and cost profile.
Information about these stages is distributed over time.
At any given point, participants can usually see the next step. They can often estimate the cost of that step. What is less visible is how many further steps will be required, how those steps will interact, and how the overall cost trajectory will develop.
Taken together, these features produce a recurring pattern.
Cost is encountered through a series of increments. Each increment is individually explicable. In combination, they can produce an outcome that was not readily foreseeable at the beginning.
How parallel pathways affect cost
Efforts to resolve the matter may continue throughout. At the same time, preparation for a possible hearing or trial often follows its own timetable.
These activities are not strictly sequential. They can overlap for extended periods.
Work done in one direction may inform the other, but it does not always reduce the need for further work. Different streams of activity can develop alongside each other.
When viewed in aggregate, this can be difficult to reconcile.
Each step may be justified when viewed in isolation. In combination, they contribute to a cost trajectory that is not easily visible as a whole.
How decision-making is affected
Timing plays a central role.
Decisions are made at points where only partial information is available. A step may be taken because it appears necessary at that time. The cost implications of that step, in combination with later steps, may only become apparent afterwards.
Information about the likely course of the matter is distributed across time and between participants. No single participant necessarily has a complete view at any one time.
As a result, cost visibility is fragmented.
As timing and scope shift, cost follows.
Predictability depends not only on estimation, but on when and how future stages become visible.
The structural pattern
Over time, a pattern becomes recognisable.
A matter may begin with a relatively clear plan. Additional steps are introduced as it evolves. Costs increase in ways that were not fully visible at the outset. Decisions about timing and scope can become harder to evaluate in real time.
Initial estimates often reflect early stages. They do not always capture how later stages may be activated, or how different pathways may proceed in parallel.
Predictability is therefore a function of visibility over time.
Under these conditions, predictability is determined less by initial estimates, and more by when stages become visible, how pathways interact, and how cost information becomes visible over time.
These features arise across many types of disputes, regardless of forum or subject matter.
