+
+This module allows to plan your resources using forecast lines.
+
+For each employee of the company, the module will generate forecast line
+records with a positive capacity based on their working time schedules. Then,
+tasks assigned to employees will generate forecast lines with a negative
+capacity which will "consume" the work time capacity of the employees.
+
+The idea is that you can then see the work capacity and scheduled work of
+people by summing the "forecasts" per time period. If you have more resources
+(positive forecast) than work (negative forecast) you will have a positive net
+sum. Otherwise you are in trouble and need to recruit or reschedule your
+work. Another way to use the report is checking when the work capacity of a
+department becomes positive (or high enough) in order to provide you potential
+customers with an estimate of when a project would be able to start.
+
+Forecast lines also come in two states "forecast" or "confirmed", depending on
+whether the consumption is confirmed or not. For instance, holidays requests
+and sales quotation lines create lines of type "forecast", whereas tasks for
+project which are in a running state create lines with type "confirmed".
+
+To get the best experience using the Forecast application you may want to install:
+
+* project_forecast_line_holidays_public module which takes public holidays into
+  account during forecast lines creation
+
+* project_forecast_line_bokeh_chart module which improves the reports of
+  project_forecast_line module by using the bokeh widget available in OCA/web
+
+.. IMPORTANT::
+   This is an alpha version, the data model and design can change at any time without warning.
+   Only for development or testing purpose, do not use in production.

+
+Usage
+=====
+
+Forecast lines have the following data:
+
+* Forecast hours: it is positive for resources (employees) and negative for
+  things which consume time (project tasks, for instance)
+
+* From and To date which are the beginning and ending of the period of the
+  capacity
+
+* Consolidated forecast: this is a computed field, which is computed as follows:
+
+  * for costs (project tasks for instance) we take the absolute value of the
+    forecast hours (so it is a positive number)
+
+  * for resources (employee capacity for a period), we take the capacity and
+    substract all the costs for that employee on the same period. So it will be
+    positive if the employee still has some free time, and negative if he is
+    overloaded with work.
+
+  * this consolidated forecast is currently converted to days to ease
+    readability of the forecast report
+
+
+Objects creating forecast lines:
+
+* employees with a forecast role will create forecast line with a positive
+  capacity and type "confirmed" for each day on which they work. This
+  information comes from their work calendar, and the different roles that are
+  linked to the employee.
+
+* draft sale orders (if enabled in the settings) will create forecast lines of
+  type "forecast" for each sale order line having a product with a forecast
+  role and start and end dates. The forecast hours are negative
+
+* confirmed sale orders don't create forecast lines. This is handled by the
+  tasks created at the confirmation of the sale order
+
+* project tasks create forecast lines if they have a linked role and planned start/end
+  dates. The type of the line will depend on the related project's stage. The
+  `forecast_hours` field is based on the remaining time of the task, which is spread
+  on the work days of the planned start and end date of the task. If the
+  current date is in the middle of the planned duration of the task, it is used
+  as the start date. If the planned end date is in the past the task does not
+  generate forecast lines (and you need to fix your planning). In case multiple
+  employees are assigned to the task the forecast is split equally between
+  them.
+
+* holiday requests create negative forecast lines with type "forecast" when
+  they are pending manager validation.
+
+* Validated holiday requests do not generate forecast lines, as they alter the
+  work calendar of the employee: the employee will not have a positive line
+  associated to his leave days.
+
+The creation of forecast lines is done either in real time when some actions
+are performed by the user (requesting leaves, updating the remaining time on a
+project task, timesheeting) and also via a cron that runs on a daily basis. The
+cron is required to cleanup lines related to dates in the past and to recompute
+the lines related to project tasks by computing the ratio of remaing time on
+the tasks on the remaining days, for tasks which are in progress. So, to start
+using consolidated forecast report you first need to set everything mentioned
+in Usage section. Then, probably run Forecast recomputation cron manually from
+Scheduled Actions or wait till cron creates records.
