2.3 Enterprise Segment
Activity Roadmap The Enterprise Segment Activity Roadmap (ESAR) consists of a table of functions, or activities, for each of the enterprise segments discussed in Section 2.1 and illustrated in the Community Model (see Figure 2‑1). The ESAR provides an index that defines the scope of activities, mapped to enterprise segments that need to be supported by developed (or purchased) NG9‑1‑1 applications. Within each enterprise segment are group identifiers, or service areas (shown as a colored header to the enterprise segment table), for the functional activities below them. The activities within each service area are the component work functions that will be performed within the NG9‑1‑1 System. Each activity within the ESAR represents a unique function the NG9‑1‑1 System
should perform.

These activities are defined by the set of attributes listed below:
• Activity Name: The name of the
Activity being described
• Activity Code: A unique code used
to identify the Activity name and its
associated service area name
• Role: A name of the job role of the
person or the functional role of a
technology that performs the Activity
• Proof-of-Concept: Yes/No—A recommendation
on whether the Activity should be
demonstrated in the Proof-of-Concept
• References: Abbreviations of the documents
used as references when defining the Activity
• Goal: A brief description of the
end result of the Activity.
