 How to plan and track employees' assignments?
 =============================================
+
+Following and planning your employees' assignments can be a heavy
+challenge especially when you manage several people. Luckily, using Odoo
+Project, you can handle it in only a couple of clicks.
+
+Configuration
+=============
+
+The only necessary configuration is to install the **Project Management**
+module. To do so, go in the application module, search for project and
+install the application.

+
+If you wish to manage time estimation, you will need to enable
+timesheets on tasks. From the **Project** application, go to 
+:menuselection:`Configuration --> Settings` in the dropdown menu. 
+Then, under **Time Work Estimation**, select the **manage time 
+estimation on tasks** option. Do not forget to apply your changes.

+
+This feature will create a progress bar in the form view of your tasks.
+Every time your salesperson will add working time in his timesheet, the
+bar will be updated accordingly, based on the initially planned hours.

+
+Manage tasks with views 
+=======================
+
+You can have an overview of your different task thanks to the multiple
+views available with Odoo. Three main views will help you to plan and
+follow up on your employees' tasks: the kanban view, the list view
+(using timesheets) and the calendar view.
+
+Create and edit tasks in order to fill up your pipeline. Don't forget to
+fill in a responsible person and an estimated time if you have one.
+
+Get an overview of activities with the kanban view
+--------------------------------------------------
+
+The Kanban view is a post-it like view, divided in different stages. It
+enables you to have a clear view on the stages your tasks are in and the
+ones having the higher priorities.
+
+The Kanban view is the default view when accessing a project, but if you
+are on another view, you can go back to it any time by clicking the
+kanban view logo in the upper right corner

+
+Add/rearrange stages
+~~~~~~~~~~~~~~~~~~~~
+
+You can easily personalize your project to suit your business needs by
+creating new columns. From the Kanban view of your project, you can add
+stages by clicking on **Add new column** (see image below). If you
+want to rearrange the order of your stages, you can easily do so by
+dragging and dropping the column you want to move to the desired
+location. You can also fold or unfold your stages by using the **setting**
+icon on your desired stage.
+
+.. image:: media/assignments06.png
+    :align: center
+
+.. tip::
+    Create one column per stage in your working process. For example, 
+    in a development project, stages might be: Specifications, 
+    Development, Test, Done.
+
+Sort tasks by priority
+~~~~~~~~~~~~~~~~~~~~~~
+
+On each one of your columns, you have the ability to sort your tasks by
+priority. Tasks with a higher priority will automatically be moved to
+the top of the column. From the Kanban view, click on the star in the
+bottom left of a task to tag it as **high priority**. For the tasks that
+are not tagged, Odoo will automatically classify them according to their
+deadlines.
+
+Note that dates that passed their deadlines will appear in red( in the
+list view too) so you can easily follow up the progression of different
+tasks.

+
+.. tip::
+    Don't forget you can filter your tasks with the filter menu.
+
+Track the progress of each task with the list view
+--------------------------------------------------
+
+If you enabled the **Manage Time Estimation on Tasks**, your employees
+will be able to log their activities on tasks under the **Timesheets**
+sub-menu along with their duration. The **Working Time Progress** bar will
+be updated each time the employee will add an activity.
+
+.. image:: media/assignments08.png

+
+As a manager, you can easily overview the time spent on tasks for all
+employees by using the list view. To do so, access the project of your
+choice and click on the List view icon (see below). The last column will
+show you the progression of each task.
+

+
+Keep an eye on deadlines with the Calendar view
+-----------------------------------------------
+
+If you add a deadline in your task, they will appear in the calendar
+view. As a manager, this view enables you to keep an eye on all
+deadlines in a single window.
+
+.. image:: media/assignments10.png
+    :align: center
+
+All the tasks are tagged with a color corresponding to the employee
+assigned to them. You can easily filter the deadlines by employees by
+ticking the related boxes on the right of the calendar view.
+
+.. tip::
+    You can easily change the deadline from the Calendar view by 
+    dragging and dropping the task to another case.
