## Understanding This Implementation Guide

This implementation guide discusses the tasks that you must complete before, during, and after you convert the company base currency to another currency.

This chapter discusses:

- Test versus production environments

- Types of tasks

### Test Versus Production Environments

You should complete the tasks in this guide twice. First, complete them in the test or conference room pilot (CRP) environment and correct any data issues in both the test and production environments. Later, when you are satisfied with the results of the base currency conversion in the test environment, complete all the tasks again in the production environment and go live (return to your normal business operations).

### Types of Tasks

The contents of this guide are divided into three primary tasks:

- Preconversion tasks

- Conversion tasks

- Postconversion tasks

Within each primary task are specific tasks that must be reviewed and completed by one or both of these types of employees:

- Application employees

  Employees who are responsible for overseeing the day-to-day activities for the applications.

- Technical employees

  Employees who are responsible for updates to the computer systems.
