An old-timer once said that there is no problem in AA that cannot be solved through 'strong sponsorship'.
One problem groups encounter is low attendance, with the accompanying difficulties of finding people to do service and collecting enough voluntary contributions to pay the group's expenses.
This is simply solved by group members holding the sponsoring of others to be their primary objective, and requiring sponsees to attend their home group as a condition of sponsorship, which has many advantages in any case.
This promptly solves the numbers, financial, and service problems.
The presence of sponsees (who will range from the newest members through to people with a few months or years) provides energy and impetus. Newer people are either in trouble or enthusiastic, as a rule, sometimes both, and this manifest need tends to galvanise members of longer standing and wrest the best from them. The primary purpose becomes clear, and the group tends to regain its focus.
