A new SIPB chair and vice-chair are taking office tomorrow, and the other night several of their predecessors took an evening to give them an orientation.

SIPB has two priorities: people and projects. Each active project has its own organizers, maintainers, and/or developers who move it forward and make its decisions, so the role of the chair and vice-chair is about keeping track of how things go, helping connect the project to outside resources and connect new contributors to the project, mediating shared resources like the machine room, and making sure that key projects get passed on from year to year.

It makes sense, then, that we spent most of our time talking about people—bringing people in the door at SIPB, making the office a welcoming place for them, drawing them into our community, and electing them as members. We hear in almost every membership election about how the organization could do better at this. Here’s a quick version of why it’s so important:

Every year, about 1/3 of student SIPB members graduate.

Put another way, in steady state:

Size of SIPB = 3 * (# new members / year)

For example, right now SIPB has 26 student members, and by my count 9 are planning to leave MIT in June. So the only way SIPB can stay as strong as it is is to get 9 new members this year, and about as many again the next year, and the next year, and so on. Fewer new members ⇒ fewer members ⇒ fewer awesome projects, fewer people to learn from, fewer people to hire away to Ksplice (ahem, maybe not everyone shares that motivation).

Fortunately, we built a good track record over the last few years:

    academic year          freshmen &
      starting     total   sophomores

        2010        ???       ???
        2009         7+        4+
        2008         9         6
        2007         8         2
        2006        10         3
        2005        10         2
        2004         5         3
        2003         4         2
        2002        10         3
        2001         8         2
        2000         3         2

From those numbers in the last five years, it’s not hard to see how we got the organization to the point where three strong candidates stood at the last election for chair, and where the office is full to crowding at nearly every Monday’s meeting. It’s also clear how it wasn’t always this way—the numbers from the 2004 and 2003 academic years led directly to the election of 2005 in which the nine-member EC comprised every student member of the SIPB.

But my favorite aspect of these numbers is in the column on the right. When I was the chair in 2008-9, I put an emphasis on getting people involved in SIPB in their first and second years. I’ve heard a lot of people’s stories over the years of showing up at SIPB as a freshman or sophomore, going away for a variety of reasons, and finally coming back two or three or more years later and becoming members. Some of them went on to become highly active and valued contributors, and it’s too bad for everyone that we didn’t succeed in bringing them in the first time around. With the record 6 freshman and sophomore new members in the 2008 academic year, I think we succeeded in turning a lot of those stories around into members who will be active students for a long time. Edward and Evan have gotten this 2009 year to outpace 2008 so far, so the new team of Jess and Greg have the chance to finish it at another record. 2010 will be theirs to create, and I wish them the best of luck in outdoing 2008 and 2009 both.
