Four (Non-Definitive) Pillars of Nonprofit Sustainability
… and how to check the health of each one
A few weeks back I spoke at a conference about organizational sustainability. It was a conversation not only in my wheelhouse, but in my deep zone of concern. As a habit, before I do such things, I usually ask colleagues (and strangers on the Internet) for their thoughts.
On this occasion, the question was “How do you define sustainability?”
As it goes with wide open-ended questions, the responses were myriad. And as I often do, I responded by asking most people to distill their responses down to one or two words. This is usually fun… and sometimes irritating.
What become clear through the dozens of responses was a set of principles—-or pillars or levers or dimensions or whatever designation suits you. I not only agreed with them, I’ve experienced them to be the truest evidence of how we ought to think about sustainability in the social sector:
Fiduciary health // Team resilience // Program relevance and adaptability // Knowledge and systems
I thought it might be fun to dive into this for the Hive community. At best, it will be insightful for those looking more deeply at sustainability. At worst, other strangers on the Internet can seek me out and argue their point. And for each principle, I’d love to offer a gut check.

Fiduciary Health (Or, do you have the financial and governance resources necessary to continue the work ahead?)
This is about the money and oversight that makes it possible for all the other work to be possible. (For most of my career, most people have told me this is the standard definition of sustainability.) Fiduciary health isn’t only about having enough funding, but about clarity, consistency, and accountability on where money comes from, how it’s used, and whether your governance structure (e.g., your board) supports smart, mission-aligned decisions.
Gut check: Create a money map. List your top five or 10 revenue sources—-earned, contributed, fee-for-service, etc. Note how much you rely on each in your budget, how stable it is, and how well it aligns with your mission. If one source feels dominant and unpredictable, you might have a fiduciary sustainability risk.
Team Resilience (Or, are you creating an environment where your team can thrive short- and long-term?)
Sustainability depends on people, not just payroll. (Although in many businesses roughly 80 percent of the budget is usually tethered to people.) Team resilience means designing structures and cultures where staff can do good work without burning out. This includes setting realistic expectations, investing in growth, and normalizing rest as a responsibility.
Gut check: Create a pace audit. For one week (two weeks max), ask each team member to track how often they work outside normal hours or skip breaks. Make it clear this is not a policing effort. Review the findings together, identify patterns, and do your best to understand why “daytime” work is spilling over. In each year of the Social Impact Staff Retention report, nonprofiteers have made it very clear they have too much to do and not enough support to get it done.
Program Relevance & Adaptability (Or, are your programs still pertinent and responsive to community needs?)
No program stays relevant forever. (Read that line again. Aloud and slowly. In your next five board meetings.) The most sustainable initiatives evolve in conversation with the communities they are meant to serve. And those initiatives have built-in feedback loops that help an organization listen, adjust, and act based on real conditions, not assumptions. (Or the whims of a board member who is still somehow on the board even though their term ended in 1989.)
Gut check: Create a mission mirror. Choose one core program and ask: if we were starting fresh, today, would we design this program the same way? If not, what has changed (in the community, in our assumptions, or otherwise) that should change our approach?

Knowledge & Systems (Or, could we keep operating smoothly if a key person left tomorrow, or we lost access to a critical platform?)
My pal Michelle Flores Vryn and I talk a lot about how dangerous it is when organizations focus on “paint over plumbing.” Nevertheless, the backbone elements of our work tend to get a backseat to flashier, distracting things. Institutional memory and operational systems allow the mission to outlive any one person or piece of software. Without them, even small transitions can (and often do) create chaos.
Gut check: Drop a guitar pic. (If you play guitar, you know a dropped pic can disappear quickly and forever.) Pick one critical role or system and ask: if this disappeared tomorrow, what would we lose—and how long would it take to recover? The bigger the gap, the more urgently that knowledge needs to be shared or documented. “Redundancy” is often a dirty word in business, but you don’t want Susan to be the only person with all the foundation grant logins.
Sustainability isn’t a destination, it’s a journey. In the way I think about this, each sustainability principle reinforces the others. Fiduciary health funds resilience. Resilient teams drive adaptability. Strong systems protect both people and resources.
So when we talk about sustainability, we’re not just talking about lasting. We’re talking about lasting well.
