Our Cape Town multi-agent orchestration follows a methodology designed for reliable, production-grade agent systems: (1) Process decomposition (weeks 1-2): breaking complex processes into agent-sized tasks. Process analysis: understanding the end-to-end business process — every step, every decision, every exception. Cape Town process analysis: working with the people who currently perform the process — understanding not just the official procedure but the judgment calls, workarounds, and exceptions that make the process actually work. Agent identification: decomposing the process into discrete agent responsibilities. Each agent: having a clear, bounded responsibility — one task type that it executes well.
Agent design principles: single responsibility (each agent does one thing — not trying to build a super-agent that does everything), clear interfaces (each agent has defined inputs and outputs — other agents interact through these interfaces, not through shared state), and failure handling (each agent knows what to do when things go wrong — retry, escalate, or fail gracefully). Orchestration design: defining how agents coordinate. Sequential (Agent A completes → Agent B starts), parallel (Agents A and B run simultaneously → Agent C processes both results), conditional (if condition X → Agent A; if condition Y → Agent B), and iterative (Agent A runs, result evaluated, if not satisfactory → Agent A runs again with feedback). Human-in-the-loop: identifying where human oversight is required — complex decisions, exception handling, and quality verification. The system: designed so humans review and approve at defined checkpoints, not at every step.
(2) Agent development (weeks 2-5): building individual agents. Agent architecture: each agent built with a consistent architecture. LLM core (GPT-4, Claude, or open-source models — the agent's reasoning engine), tools (APIs, databases, and external services the agent can use — each tool with defined input/output and error handling), memory (agent state — conversation history, task context, and accumulated information), and guardrails (boundaries on agent behaviour — what it can and cannot do, quality thresholds, and safety constraints).
South African-specific agents: agents that understand South African context — FICA verification (understanding SA ID numbers, proof of address requirements, and PEP screening against SA-specific lists), South African financial calculations (NCR affordability calculations, SARS tax rules, and medical aid benefit structures), South African logistics (understanding SA geographic zones, carrier capabilities, and delivery challenges), and multilingual processing (handling English, Afrikaans, isiZulu, and isiXhosa content — agents that can process documents and communications in multiple South African languages). Tool integration: connecting agents to the systems they need. API integrations (CRM, ERP, banking systems, government databases), document processing (OCR, PDF extraction, and image analysis), communication (email, SMS, WhatsApp — agents able to send notifications and collect information through South African communication channels), and data sources (credit bureaus, company registrations, and public records). Testing each agent independently: verifying that each agent performs its task correctly before integrating into the orchestration.
Unit testing: defined test cases for each agent — inputs, expected outputs, and edge cases. (3) Orchestration layer (weeks 4-6): coordinating multiple agents. Orchestration framework: building the system that coordinates agents. Workflow engine (defining the sequence of agent activities — sequential, parallel, and conditional flows), state management (tracking the overall process state — which agents have completed, what data has been collected, and where the process currently stands), error handling (what happens when an agent fails — retry logic, fallback agents, escalation to human, and process recovery), and monitoring (real-time visibility into multi-agent execution — which agents are running, what they're doing, and how long they're taking). Technology: LangGraph or custom orchestration — depending on complexity. LangGraph: our default for standard multi-agent workflows — providing graph-based workflow definition with built-in state management and error handling. Custom orchestration: for complex workflows requiring specific coordination patterns.
Load shedding resilience: the orchestration layer designed for South African infrastructure realities. Task persistence (agent work-in-progress persisted to database — if power is lost, the system resumes from the last checkpoint when power returns), async processing (agents communicate through message queues — decoupled from real-time connectivity), and graceful degradation (if an external service is unavailable — agent queues the task and retries when the service returns, rather than failing the entire workflow). (4) Integration and testing (weeks 5-7): connecting and validating. End-to-end testing: the complete multi-agent workflow tested with real-world scenarios. Happy path (standard cases flowing through all agents correctly), exception cases (missing data, failed verifications, unusual inputs — testing that exceptions are handled correctly), concurrent execution (multiple workflows running simultaneously — testing that agents handle concurrent requests without interference), and performance (end-to-end processing time, per-agent latency, and system throughput under expected load).
South African testing: testing with South African data — SA ID numbers, South African addresses, Rand-denominated amounts, and South African regulatory scenarios. The testing: not using generic test data but realistic South African business scenarios. Human review integration: testing the human-in-the-loop touchpoints — ensuring that human reviewers receive the right information at the right time, can make decisions, and the workflow continues correctly after human input. (5) Deployment and monitoring (weeks 6-8+): production deployment. Deployment: containerised deployment (Docker/Kubernetes) on South African or international cloud infrastructure (AWS Cape Town region when available, or AWS EU/Ireland for proximity). Configuration: agent behaviour, thresholds, and routing rules configurable without code deployment — enabling the business to tune agent behaviour based on operational experience. Monitoring: comprehensive multi-agent monitoring.
Agent performance (per-agent success rate, latency, and error rate), workflow performance (end-to-end processing time, completion rate, and exception rate), quality metrics (accuracy of agent outputs — measured against human review or known-correct outcomes), and cost tracking (LLM API costs per workflow — ensuring multi-agent processing remains cost-effective). Continuous improvement: weekly review of agent performance — identifying agents that underperform, workflows that fail, and opportunities for optimisation. Agent retraining: updating agent prompts, tools, and logic based on production experience.
