Scope

Template Library

Scope Template

Define boundaries clearly so requirements, architecture, implementation, and release decisions do not expand by accident.

ES-101 Scope Boundaries

Template purpose

Use this template to define the project boundary.

Scope is not only what the team plans to build. It also includes exclusions, deferred items, prohibited behavior, trust boundaries, data boundaries, AI boundaries, and open questions that must not be silently converted into assumptions.

Scope summary

<Brief description of the current project boundary.>

In scope

List capabilities, responsibilities, contexts, users, outcomes, or evidence responsibilities included in the current project boundary.

ID In-Scope Item Rationale Evidence Expected Later
IN-001 <in-scope item> <why included> <requirements, design, tests, operational evidence, governance review>

Out of scope

List items explicitly excluded from the current project.

ID Out-of-Scope Item Reason Excluded Revisit Condition
OUT-001 <out-of-scope item> <reason> <condition, date, stage, or "not planned">

Deferred

List items that may matter later but are not part of the current increment.

ID Deferred Item Why Deferred Future Trigger
DEF-001 <deferred item> <reason> <future condition>

Explicitly prohibited

List things the system should not do.

Examples may include:

  • no autonomous high-impact decisions;
  • no use of unapproved sensitive data;
  • no replacement of required human review;
  • no unreviewed AI-generated outputs in operational decisions;
  • no hidden data collection;
  • no release without readiness evidence.
ID Prohibited Behavior Rationale Enforcement Evidence Later
PRO-001 <prohibited item> <reason> <guardrail, review, test, monitoring, policy>

AI scope boundaries

Question Boundary
Is AI part of the system scope? <yes / no / unknown / limited>
What AI behavior is in scope? <behavior>
What AI behavior is out of scope? <behavior>
What AI behavior is prohibited? <behavior>
What human oversight is required? <oversight>
What AI evidence must be preserved? <logs, prompts, outputs, review notes, evaluation records>

Data scope boundaries

Data Category In Scope? Restrictions Evidence Needed Later
<data category> <yes / no / limited / unknown> <privacy, security, access, retention, consent, quality> <data review, access review, test data record, governance approval>

Operational scope boundaries

Area Boundary
Supported users <users>
Supported environments <environments>
Support hours or model <support model>
Monitoring responsibility <owner>
Escalation responsibility <owner>
Rollback / stop authority <owner>

Open scope questions

ID Question Owner Needed By
SQ-001 <question> <owner> <date or stage>

Scope rationale

Explain why the current boundary is appropriate.

<Brief rationale.>

Review checklist

  • [ ] In-scope work is specific enough to guide requirements.
  • [ ] Out-of-scope work is explicit.
  • [ ] Deferred items are not hidden as assumptions.
  • [ ] Prohibited behavior is clearly stated.
  • [ ] AI boundaries are addressed where relevant.
  • [ ] Data boundaries are addressed where relevant.
  • [ ] Operational boundaries are addressed where relevant.
  • [ ] Open scope questions are tracked.

Continue to Assumptions

Record assumptions that could affect requirements, architecture, implementation, or operation.
