# 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.
