+How to motivate and reward my salespeople?
+==========================================
+
+Challenging your employees to reach specific targets with goals and
+rewards is an excellent way to reinforce good habits and improve your
+salespeople productivity. The **Gamification** app of Odoo gives you simple
+and creative ways to motivate and evaluate your employees with real-time
+recognition and badges inspired by game mechanics.
+
+Configuration
+=============
+
+From the **Apps** menu, search and install the **Gamification** module.
+You can also install the **CRM gamification** app, which will add some
+useful data (goals and challenges) that can be used related to the
+usage of the **CRM/Sale** modules.

+
+Create a challenge
+==================
+
+You will now be able to create your first challenge from the menu 
+:menuselection:`Settings --> Gamification Tools --> Challenges`.
+
+.. note::
+    As the gamification tool is a one-time technical setup, 
+    you will need to activate the technical features in order 
+    to access the configuration. In order to do so, click on 
+    the interrogation mark available from any app (upper-right) 
+    and click on **About** and then **Activate the developer mode**.

+
+A challenge is a mission that you will send to your salespeople. It can
+include one or several goals and is set up for a specific period of
+time. Configure your challenge as follows:
+
+-   Assign the salespeople to be challenged
+
+-   Assign a responsible
+
+-   Set up the periodicity along with the start and the end date
+
+-   Select your goals
+
+-   Set up your rewards (badges)
+
+.. note::
+    Badges are granted when a challenge is finished. This is either 
+    at the end of a running period (eg: end of the month for a 
+    monthly challenge), at the end date of a challenge 
+    (if no periodicity is set) or when the challenge is manually closed.
+
+For example, on the screenshot below, I have challenged 2 employees with
+a **Monthly Sales Target**. The challenge will be based on 2 goals: the
+total amount invoiced and the number of new leads generated. At the end
+of the month, the winner will be granted with a badge.

+
+Set up goals
+------------
+
+The users can be evaluated using goals and numerical objectives to
+reach. **Goals** are assigned through **challenges** to evaluate (see
+here above) and compare members of a team with each others and through
+time.
+
+You can create a new goal on the fly from a **Challenge**, by clicking on
+**Add new item** under **Goals**. You can select any
+business object as a goal, according to your company's needs, such as :
+
+-   number of new leads,
+
+-   time to qualify a lead or
+
+-   total amount invoiced in a specific week, month or any other time
+    frame based on your management preferences.

+
+.. note::
+    Goals may include your database setup as well (e.g. set your 
+    company data and a timezone, create new users, etc.).
+
+Set up rewards
+--------------
+
+For non-numerical achievements, **badges** can be granted to users.
+From a simple *thank you* to an exceptional achievement, a badge is an
+easy way to exprimate gratitude to a user for their good work.
+
+You can easily create a grant badges to your employees based on their
+performance under :menuselection:`Gamification Tools --> Badges`.
