Wizards are popup windows that are used to guide you step by step through the process of creating an object, or performing an operation on an object. A wizard is a user interface consisting of a sequence of steps that lead the user through a specific task one step at a time, the user clicks next to move through the steps. It might not be necessary to complete all the steps present in a wizard. Once the required information is provided, you can click FINISH / OK button to submit the data to the server. A wizard can consist of one or many steps which must be completed in a certain order.

A clerk is a user interface consisting of a tab control that has two or more tabs. Data can be entered and the user can complete tabs in any order. A user may freely move from one tab to another, even if the current tab is not complete. A clerk is not meant to guide users sequentially through a task, and is typically used for frequent and easily accomplished tasks.

The layout for single step wizards and multi step wizards will be different. The single step wizard will not have “Step icons”, “Step links” and “Back / Next navigation buttons”.
