# Builder Path - Advanced

## Advanced builder path

Configure governance controls. Operate workflows reliably in production. Standardize building blocks for teams.

### Outcomes

By the end, you will be able to:

* Configure authentication and role-based access.
* Restrict access to connections and knowledge bases.
* Control which model providers are available to your workspace.
* Implement fallbacks and human approval where needed.
* Monitor usage and evaluate workflow quality over time.

### The path

{% stepper %}
{% step %}

### 1) Configure access controls

Define who can build, run, and publish workflows. Restrict access to workspaces, folders, connections, and knowledge bases.

* [Role-Based Access Controls (RBAC) and Groups](https://docs.stackai.com/welcome-to-stackai/security-and-governance/security-in-stackai/role-based-access-controls-rbac-and-groups)
* [Workspace and Folder Access](https://docs.stackai.com/welcome-to-stackai/security-and-governance/security-in-stackai/workspace-and-folder-access)
* [Connection and Knowledge Base Permissions](https://docs.stackai.com/welcome-to-stackai/security-and-governance/security-in-stackai/connection-and-knowledge-base-permissions)
  {% endstep %}

{% step %}

### 2) Govern models and data

Control which providers and models are available. Define how data is handled for your deployment.

* [LLM Provider Governance](https://docs.stackai.com/workflow-builder/core-nodes/ai-agent-node/llm-hosting-and-governance/llm-provider-governance)
* [Security & Privacy](https://docs.stackai.com/welcome-to-stackai/security-and-governance/security-and-privacy)
* [AI Governance](https://docs.stackai.com/welcome-to-stackai/security-and-governance/ai-governance)
  {% endstep %}

{% step %}

### 3) Implement reliability controls

Handle expected failures with fallbacks. Add human review steps where required.

* [Fallback & Error Handling](https://docs.stackai.com/guides-and-tips/stackai-hacks/handling-errors-and-fallback)
* [Human in the Loop](https://docs.stackai.com/workflow-builder/core-nodes/stackai/human-in-the-loop)
* [Delay Node](https://docs.stackai.com/getting-started/learning/stack-ai-curriculum/broken-reference)
  {% endstep %}

{% step %}

### 4) Monitor and evaluate in production

Monitor usage, latency, and errors. Evaluate outputs against defined criteria.

* [Analytics](https://docs.stackai.com/agentic-adoption-and-security/observability/analytics)
* [Evaluator](https://docs.stackai.com/agentic-adoption-and-security/observability/evaluator)
* [Adding Advanced Logging for Analytics](https://docs.stackai.com/guides-and-tips/stackai-hacks/adding-advanced-logging-for-analytics)
  {% endstep %}

{% step %}

### 5) Standardize reusable components

Create reusable subflows and shared utilities. Use code and custom APIs for supported extensions.

* [StackAI Project Node](https://docs.stackai.com/workflow-builder/utils-logic-and-others/utils/stackai-project-node)
* [Loop Subflow](https://docs.stackai.com/workflow-builder/utils-logic-and-others/logic/loop-subflow)
* [Custom API](https://docs.stackai.com/workflow-builder/utils-logic-and-others/utils/custom-api)
