1. Introduction & Goals

What is Finnest?

Finnest (commercial name: Hexis) is an AI-native, multi-industry workforce management platform for Australian employers in compliance-heavy industries — labour hire, construction, healthcare, mining, security, and similar. It handles the full employment lifecycle: recruit, onboard, roster, timekeep, pay, and keep everyone compliant with Fair Work, state awards, and industry-specific credential regimes.

What makes it different from every incumbent (Deputy, Tanda, Employment Hero, Connecteam, ELMO, Rostering.com.au):

  • AI-native by default. Every screen has a command bar (Cmd+K); every long-running task can be delegated to an autonomous agent; every domain publishes typed tools via Model Context Protocol so AI assistants act inside the business, not outside it.
  • Compliance auto-blocking as a first-class architectural constraint. Non-compliant workers cannot be rostered, paid, dispatched, or given equipment — enforced synchronously, not via after-the-fact reporting.
  • Dual deployment from one codebase. Commercial SaaS (Anthropic Direct) and IRAP-certified government-sensitive (AWS Bedrock Sydney) from the same Elixir release, via runtime configuration.

Why does it exist?

Two reasons, in order:

  1. Existing v2 product (ASG Central, built on Laravel) has hit its architectural ceiling. Adding a new industry, integrating award interpretation, or rolling out AI agents each require cross-cutting rewrites. ADR-0011 records the decision to migrate to Elixir/Phoenix; ADR-002-F records the supervised-modular-monolith pattern that replaces the Laravel monolith.
  2. AI-native workforce management is an emerging category with no dominant incumbent. Every competitor audited in brainstorm-12 treats AI as a bolted-on chat window. Finnest treats it as the primary interaction model.

Goals (NFR drivers)

The 19 architectural drivers that shape every structural decision are catalogued in full in architecture/architecture.md §Architectural Drivers. The top six, which dominate day-to-day trade-offs:

Goal What it means
Concurrent AI agent swarm Hundreds of GenServer-based agents per node, per-agent fault isolation, hot code reload
IRAP OFFICIAL:Sensitive Bedrock Sydney AI, 15-minute sessions, FIDO2 mandatory, ISM-listed security boundary
Compliance auto-blocking Non-compliant workers blocked synchronously at write time in 5 domains
Multi-tenant isolation org_id at every layer; agent processes never reused across tenants
AI cost ceiling 70 %+ of queries handled at $0; per-org budget circuit-breaker
Multi-industry (10 profiles) Industries are JSONB configuration, never code branches

Stakeholders

Role Interest
HR administrators Primary users — daily roster + compliance + payroll work
Workers / field staff Mobile-first: accept shifts, clock in/out, update credentials
Clients (labour hire) Approve workers, confirm timesheets, receive compliance evidence
Managers Approve leave, dispatch jobs, read dashboards
Auditors (IRAP assessors) Read-only access to immutable audit trail, compliance attestations
Regulators (Fair Work, WHS) Automated data extracts and compliance reporting
Investors / board High-level status; read this documentation

Reading path for new stakeholders

Given Finnest's breadth, a brand-new reader should walk the documentation breadth-first, then depth:

  1. This page (1. Introduction)
  2. 3. System Context — 1 diagram + 1 page
  3. 5. Building Blocks — the 21 OTP apps at a glance
  4. Pick one module that matters to the reader and go deep via architecture/architecture.md or the companion docs

That sequence costs ~30 minutes and produces a defensible mental model.
