When it comes to small group multiplication, there is the "ideal" and then there is "reality". The ideal is that small group multiplication occurs through the practices of leadership apprenticing and group birthing. The reality is that there is "labor" involved, but take heart, "labor" is a good thing and you might have more resources available to you than you think.
The concept of leadership apprenticing and birthing has Biblical roots (see Luke 10:2; 2 Tim. 2:2) and basically goes like this: Early in the small group's life, an apprentice leader(s) is raised up from among the group and is prepared to lead a group.

The maximum number of people in a small group where these dynamics can still function effectively varies, but typically when a group grows to 10-20 members, many discipleship functions begin to break down, including lack of urgency to recruit new members and reduced commitment of existing group members.

However, the results have always produced more "fruit" than was being produced before the birth. That's not to say we didn't have some unhealthy "baby" groups for awhile, but through ...
