The core design-and-launch loop

Step
In short Every device follows the same cycle — design, price, manufacture, launch, review — and repeating it well is how you grow.

Before you hand anything to your team, lock in the specs and check what one unit will cost to make. The launch screen shows your cost price, factory preparation costs, and how much cash you currently have, so compare those numbers before you commit. After launch, critics' reviews and live sales figures tell you what to improve next.

  1. Choose specs pick screen size, cameras, corners, buttons, colour, finish, and logo for your device.
  2. Check the unit cost every time you swap a part, the cost-per-device display updates, so read it before moving on.
  3. Set the price find a number that covers your costs and still attracts buyers.
  4. Hand off to your team instruct them to manufacture the device.
  5. Run a marketing campaign this is what actually puts the product in front of customers.
  6. Read the critics and sales data use that feedback to plan your next device.
