Role model

Responsibility, governance, and reliable decision boundaries

In this model, roles are not just labels, but operational control points. Each role works on clearly bounded units of work, produces defined artifacts, and keeps decision space separated so that speed, reviewability, and traceability can scale together.

Governance view

Why role separation is critical for control and auditability

The project organization deliberately relies on strict role separation. The goal is not bureaucracy, but reliable control: when each role makes only the decisions it is meant to make, product steering, technical implementation, validation, and documentation remain clearly separated and later fully understandable.

In regulated or security-sensitive environments, this separation is more than organizational hygiene. Jira status, role labels, Current Summary, and Result Summary remain defensible only when the role working on a ticket actually fits the task. Otherwise semantics blur, and a quick delivery later turns into an evidence problem.

Executive

Strategic and escalation authority

Responsibility

sets priorities, resolves escalations, and gives direction
clears blockers when they affect product, budget, or strategy

Typical artifacts

approvals, prioritization directives, escalation decisions

Boundary

does not operate permanently inside DEV, QA, or DOC tickets.

PM

Product and business perspective

Responsibility

describes product goals, user value, problem space, and audiences
writes stories and business expectations

Typical artifacts

stories, epics, scope descriptions, product acceptance

Boundary

does not write detailed DEV, QA, or DOC work packages.

PO

Operational orchestration and integration role

Responsibility

breaks stories into actionable role tickets
manages sequencing, status flow, dependencies, and escalations
keeps Current Summary, role labels, and target status consistent

Typical artifacts

role tickets, breakdown structures, status decisions, review re-entry work

Boundary

does not implement the technical solution and does not replace the validation work of other roles.

DEV

Technical implementation role

Responsibility

implements technical work packages and assesses technical risks
delivers verifiable result artifacts and minimal handover information

Typical artifacts

code changes, technical notes, DEV results, run and validation hints

Boundary

does not make product prioritization decisions or final QA acceptance decisions.

QA

Validation and assessment role

Responsibility

checks results against acceptance criteria and visible artifacts
states deviations, risks, and remaining points clearly

Typical artifacts

QA results, accept/reject recommendations, traceable findings

Boundary

does not build features and does not replace PO prioritization.

DOC

Documentation and consolidation role

Responsibility

maintains user, developer, and project documentation on a confirmed basis
makes documentation gaps and missing approvals visible
protects structure, language quality, and traceability of result artifacts

Typical artifacts

HTML and Markdown documentation, DOC results, release and handover texts

Boundary

does not invent content and does not replace business or technical approval.

Specialization

When additional roles become relevant for risk, platform, or approval

Typical specialist roles

Security
Release Engineering
Architecture
Website
UX
App Store

What distinguishes them from core roles

they are engaged deliberately and on demand
they do not create new core tickets outside the PO flow
they deliver focused expert outputs rather than general project steering

Business impact

What strong role separation improves in practice

Visible returns instead of hidden cross-role work

When information is missing, the responsible role escalates visibly instead of silently completing work that belongs to another role.

More stable ticket closures

Owner Role, Result Summary, and next role remain consistent because ticket intent and role semantics fit each other.

Better onboarding ability

New contributors can quickly understand from role, status, and ticket text what is expected of them and what is not.

Stronger evidence in critical-infrastructure and audit contexts

When responsibility and decision-making stay clearly separated by role, changes, approvals, and rationales become much easier to trace in certification-related environments.
