Thibault FrançoisandThibault Delavallée eca1b7aeaf [IMP] crm: ensure constant lead filling when assigning
PURPOSE

All unassigned leads should be assigned to teams as soon as possible to ease
lead analysis.

Purpose of assign thresholds is to ensure sales people receive at least this
amount of leads within 30 days, counting lost and won leads. Giving them leads
regularly is also one goal of automatic assign.

SPECIFICATIONS

Counting every lead whatever its state may lead to an inconvenient situation.
If a salesman always reaches its maximum every days he will always receive the
number of lead he got 30 days ago. For example if the salesman goes in holidays
for few days and set the max to 0 he receives no lead during his vacation.
Then after a few days of assign he reaches its maximum and receive 0 leads
for a few days. This leads to having windows of leads that repeat themselves
every 30 days.

   * Solution: do not limit at maximum capacity anymore. Compensation is voided
     if limit is achieved. However asked assignment is done. Salesman could
     receive more than its max capacity but 30 days window ensure old leads
     are regularly going out of count.

``assignment_max`` is now more a mean target of leads to be assigned during
a 30 days window than a real maximum capacity. Field is renamed accordingly.

When based on cron configuration purpose of cron is to assign leads to
sales persons. Assigned workload is set to the workload those sales
people should perform between two cron iterations. If their maximum
capacity is reached assign process will not assign them any more lead.
e.g. cron is active with interval_number 3, interval_type days. This
means cron runs every 3 days. Cron will assign leads for 3 work days
to salespersons each 3 days unless their maximum capacity is reached.
If cron runs on an hour- or minute-based schedule minimum assignment
performed is equivalent to 0.2 workdays to avoid rounding issues.
Max assignment performed is for 30 days as it is better to run more
often than planning for more than one month. Assign process is best
designed to run every few hours (~4 times / day) or each few days.

""" Allocate leads to teams given by self. This method sets ``team_id``
field on lead records that are unassigned (no team and no responsible).
No salesperson is assigned in this process. Its purpose is simply to
allocate leads within teams.
This process allocates all available leads on teams weighted by their
maximum assignment by month that indicates their relative workload.
Heuristic of this method is the following:
* find unassigned leads for each team, aka leads being
* without team, without user -> not assigned;
* not in a won stage, and not having False/0 (lost) or 100 (won)
probability) -> live leads;
* if set, a delay after creation can be applied (see BUNDLE_HOURS_DELAY)
parameter explanations here below;
* matching the team's assignment domain (empty means
everything);
* assign a weight to each team based on their assignment_max that
indicates their relative workload;
* pick a random team using a weighted random choice and find a lead
to assign:
* remove already assigned leads from the available leads. If there
is not any lead spare to assign, remove team from active teams;
* pick the first lead and set the current team;
* when setting a team on leads, leads are also merged with their
duplicates. Purpose is to clean database and avoid assigning
duplicates to same or different teams;
* add lead and its duplicates to already assigned leads;
* pick another random team until their is no more leads to assign
to any team;
This process ensure that teams having overlapping domains will all
receive leads as lead allocation is done one lead at a time. This
allocation will be proportional to their size (assignment of their
members).
