Illustrative reference architecture. Validate requirements for your organization.
Illustrative architecture: A consulting team prepares a milestone review for a client transformation program. Deliverables are spread across workspaces, acceptance criteria live in a statement of work, and staffing changes affect the schedule. Agents assemble a review packet while engagement leaders retain client commitments and professional judgments.
Problem
A polished progress summary can treat an uploaded draft as an accepted deliverable or omit a scope change hidden in meeting notes. Reusing prior-client examples also risks confidentiality leakage when shared knowledge stores lack engagement boundaries.
Why a multi-agent system?
Scope, delivery-evidence, capacity, and briefing specialists inspect distinct systems. A milestone workflow separates contractual criteria, observed evidence, and proposed changes so leaders can make a concrete decision.
Intended outcome
The intended result is a reviewable operational decision with source evidence and explicit ownership. Measure preparation effort and unrecognized delivery gaps, not just report throughput. A useful assistant makes commitments and evidence easier to inspect while preserving professional accountability and client confidentiality.
Specialist agent team
Scope evidence agent
Retrieve signed scope and approved changes with acceptance criteria.
Tools
Contract repository
change register
Authority boundary
Cannot interpret disputed terms as a binding legal conclusion or expand scope.
Delivery verifier
Match deliverable versions to required review and acceptance evidence.
Tools
Project workspace search
artifact manifest reader
Authority boundary
Cannot mark client acceptance from internal draft status.
Capacity planner
Compare approved work with staffing availability and dependencies.
Tools
Resource planning API
schedule simulator
Authority boundary
Cannot assign staff or promise dates without leader approval.
Client briefing agent
Draft status, unresolved decisions, and proposed next steps with citations.
Tools
Engagement report draft tool
approved template library
Authority boundary
Cannot contact clients or issue commercial commitments autonomously.
Enterprise systems
Engagement management platform
Owns milestones, assignments, approved plans, and commercial change records.
Client document workspace
Stores scoped artifacts and explicit internal or client acceptance states.
Resource and finance systems
Supply staffing availability, budget facts, and approved billing data through role-limited adapters.
Architecture diagrams
Engagement delivery evidence coordinator — logical architecture — Specialists produce bounded findings; the evidence ledger preserves source versions and human decisions before an authorized adapter changes a system of record.
Failure and decision sequence — An internal draft is mistaken for client acceptance. The workflow records unresolved work and resumes only after the source state and reviewer authority are checked.

Runtime flow
1
Open milestone review
Bind the review to engagement, reporting date, contract revision, and accountable delivery leader.
2
Collect acceptance criteria
Retrieve signed scope and approved changes; retain unresolved commercial questions separately from operational requirements.
3
Inspect delivery evidence
Map each criterion to the exact artifact version and acceptance record, exposing missing or provisional evidence.
4
Evaluate capacity constraints
Run bounded schedule scenarios using actual availability and dependencies without assuming overtime or unapproved role substitutions.
5
Prepare leader decision
Show accepted work, remaining gaps, forecast assumptions, and proposed client questions for engagement-leader review.
6
Record approved commitments
Publish the reviewed report or change request through existing channels and track client acknowledgement independently of internal approval.
Failure recovery
An internal draft is mistaken for client acceptance.
Detect: Acceptance registry lacks the required client signoff for the artifact version.
Recover: Mark the milestone unaccepted and request the missing review without rewriting the historical status.
A retrieved example belongs to a restricted prior engagement.
Detect: Engagement access policy rejects the document's client and purpose attributes.
Recover: Exclude it and use an approved reusable asset or independently authored example.
Security & decision boundaries
Enforce client and engagement isolation across retrieval, caches, and report exports.
Distinguish draft, internally reviewed, client-submitted, and client-accepted deliverables.
Bind commercial commitments to signed scope and approved change records.
Require leader approval before client communications, staffing assignments, or schedule promises.
Exclude confidential personnel and billing details from broad delivery summaries.
Operational metrics
Measurement definitions, not promised improvements.
Acceptance evidence coverage
Milestone criteria linked to valid acceptance evidence divided by criteria claimed complete.
Review preparation time
Time from reporting cutoff to leader-reviewable milestone packet.
Forecast revision rate
Published forecasts changed after unrecorded capacity or scope facts emerge divided by published forecasts.
Confidentiality filter quality
Authorized reusable assets correctly available and restricted client assets correctly denied in a curated evaluation.
Architecture tradeoffs
Decision
Benefit
Cost
Acceptance-driven reporting
Prevents activity volume from masquerading as delivered value.
Requires explicit acceptance metadata from client workflows.
Integrated capacity scenarios
Connects plans to staffing reality.
Resource data may lag informal assignments or absences.
Engagement isolation
Protects client confidentiality.
Reduces convenient reuse unless knowledge is deliberately approved for sharing.
Rollout plan
Completed engagement replay
Leaders verify acceptance states, scope changes, and restricted-client retrieval using known cases.
Shadow milestone pilot
One delivery team reviews draft packets and checks forecast assumptions without client publication.
Approved reporting integration
Reviewed reports launch after stale-acceptance, access-boundary, and scope-revision exercises pass.
