An important characteristic of DSE is that Evidence is not merely preserved, but maintained in a structure that allows it to be retrieved, traced, and analyzed later at different levels. Even when large volumes of Logs and Records concerning Decisions are retained, they are difficult to use effectively for Audit or Governance if they are not related to one another or if the required information cannot be retrieved.

By preserving Evidence within a common structure, DSE enables the same Evidence to be used through three different Views.

The first is the Individual View. By examining a single DSE, it is possible to inspect the state that existed when a particular Decision was formed. Input Content, Fact, Evaluation, Policy, Authority, Process Record, Model / Context, and other relevant elements can be referenced together as a single Evidence Record, allowing why that Decision was formed to be examined at the individual Decision level. This corresponds to the basic principle of One Decision = One DSE.

The second is the Sequential View. Within a Business Flow, Content generated by one Decision may become the Input to the next Decision and subsequently connect to further Decisions. By tracing related DSEs through these relationships among Content and Decisions, it becomes possible to reconstruct the sequence and relationships through which multiple Decisions were formed. The process can also be traced backward from the final Output, allowing an entire Decision Process to be reconstructed as Evidence.

The third is the Cross-DSE View. Rather than following the sequence of Decisions, this View extracts common Fields such as Policy, Evaluation, or Authority across multiple DSEs. This enables aggregation, comparison, Audit, and Analysis of particular Fields. For example, Policy changes, shifts in Evaluation, or changes in Authority can be analyzed across multiple Decisions.

These three Views do not represent different forms of Evidence. Rather, they provide different ways of using the same structured DSE according to the purpose at hand. A single Decision can be examined in depth, a chain of Decisions can be traced, or large numbers of Decisions can be compared and analyzed across common Fields.

DSE must therefore do more than preserve Evidence without loss. The preserved Evidence must remain searchable, traceable, comparable, and analyzable over time.

Evidence must not merely be preserved. It must remain usable.
