# Building Stages

> What happens during each phase of the Plan Casting process.

A Plan Cast moves through several stages, each handling a specific part of turning your business plan into a working product. Here is what happens at each step.

## Stage overview

| Stage | What you see | What happens behind the scenes |
| - | - | - |
| Tech Discovery | A friendly chat about your product's needs | AI analyzes your plan and selects the right technology |
| Requirements | "Understanding your requirements..." | Detailed product requirements are generated from your plan |
| Specifications | "Creating your product plan..." | Technical specifications and screen designs are created |
| Review checkpoint | You review and approve specifications | Building pauses until you are satisfied |
| Validation | "Checking everything is consistent..." | Specifications are cross-checked for completeness |
| Building | "Building your product..." | Code is written for every feature |
| Quality checks | "Running quality checks..." | Security, accessibility, and performance audits run |
| Final review | Quality report for your review | Building pauses for your approval |
| Ready to deploy | Your product is complete | Waiting for you to click Deploy |

## What you need to do

Most stages run automatically. You only need to act at two points:

1. **Review checkpoints** -- review the generated specifications and approve, request changes, or add notes
2. **Deployment** -- click Deploy when you are ready to go live

Everything else happens in the background. You can close your browser and come back later.

## How long does it take?

Total Plan Cast time varies based on your product's complexity:

| Product complexity | Typical total time |
| - | - |
| Simple (5-10 features) | 4-8 hours |
| Medium (10-20 features) | 8-16 hours |
| Complex (20+ features) | 16-24 hours |

<Note>
  These times include the automated building stages only. Time spent at review checkpoints (where
  you review and approve) is not counted -- take as long as you need.
</Note>

## Pausing and resuming

The building process can be paused and resumed at any time:

* **Automatic pauses** -- the process pauses at review checkpoints, waiting for your input
* **Error pauses** -- if something goes wrong, the process pauses and notifies you
* **Manual resume** -- if a Plan Cast was interrupted (network issue, service outage), it automatically picks up from the last checkpoint

You are never charged for time spent waiting at review checkpoints or during pauses.
