The answer isn’t “everyone who wants to be there.” It’s everyone whose voice is critical to the plan.
A client called me before a strategic planning engagement because his board chair wanted to invite over 30 people to the retreat. He knew it was too many but needed a way to make the case for a smaller group. That conversation — who belongs in the room and who doesn’t — is one I have with almost every client.
The instinct to include more people is understandable. Leaders want buy-in. They want diverse perspectives. They don’t want anyone to feel excluded. But a strategic planning retreat isn’t a town hall. It’s a working session where a specific group of people needs to make decisions about the organization’s future. And the composition of that group directly affects the quality of those decisions.
Think Voices, Not Headcount
The question isn’t “how many people should we invite?” It’s “whose voice is critical to building a plan that reflects reality and will actually get executed?“
That’s a different filter. It shifts the conversation from inclusion for its own sake to intentional selection based on what each person brings to the table. Every seat in the room should represent a perspective the planning team can’t afford to miss — operational insight, financial reality, stakeholder experience, market knowledge, or governance authority.
What I caution against is duplication. You don’t need four people from marketing when one can represent that function’s perspective. You don’t need three people from HR when a single leader can speak to workforce challenges and capacity. Every duplicate seat dilutes the conversation and slows decision-making without adding a new perspective.
Bring in Perspectives You Don’t Usually Hear
Some of the most valuable contributions I’ve seen in planning retreats came from people who aren’t typically in the room.
For a school, we invited an alumni student and a parent to join the planning team. Their perspectives on the institution’s actual impact — versus what leadership assumed — changed the direction of several strategic priorities. For a nonprofit, including a representative from a partner community-based organization added a frontline view that the board didn’t have access to otherwise.
These aren’t token seats. When the right outside voice is at the table, the plan gets grounded in the experience of the people the organization actually serves. Where it’s appropriate, I recommend it. But the key phrase is “where it’s appropriate.” Each situation is different, and not every retreat needs external participants. The decision should be based on what perspectives are missing from the leadership team, not on a general principle of inclusiveness.
The Board Transition Problem
This is one of the most important and most overlooked planning considerations — especially for nonprofits and associations.
If your organization has incoming board members who haven’t yet started their terms, strongly consider postponing the retreat until they can participate. I can’t emphasize this enough.
When outgoing board members make strategic decisions at a planning retreat, the incoming members — the people who will actually be responsible for supporting and executing the plan — had no voice in shaping it. They didn’t debate the trade-offs. They didn’t hear the stakeholder feedback. They weren’t part of the discussions that built alignment around priorities.
What happens next is predictable: the new board members feel no ownership of the plan. They question decisions they weren’t part of. Momentum stalls. And within six months, the plan gets quietly set aside while the new board figures out its own direction. The investment in the entire strategic planning process is wasted.
If you’re in a board transition period, wait. A plan built with the right people is worth more than a plan built on time.
When Clients Want to Include More People
It happens regularly. A client identifies 10 additional staff members or stakeholders they’d like involved in the process. My recommendation: give them a voice, but not necessarily a seat at the retreat.
There are better ways to include broader perspectives without overcrowding the planning room. I’ll convene focus groups with specific stakeholder segments to surface their insights in a structured setting. Or I’ll conduct one-on-one interviews with key individuals whose perspective matters but whose presence at a two-day retreat isn’t practical. And for larger groups, a well-designed survey can capture input from dozens or even hundreds of people. This is all part of the preparation work that happens before the retreat — learn more about how to prepare your organization for strategic planning.
The key with surveys is that they need to be structured to elicit real insights and perspectives that inform the plan — not just satisfaction scores or generic feedback. The questions should surface what stakeholders actually experience, what they need, what’s working, and what isn’t. That information then feeds into the briefing materials the planning team reviews before the retreat.
This way, every important voice contributes to the plan — but the retreat itself stays focused on the group that needs to make the decisions.
What Happens When the Room Is Too Big
When organizations ignore this advice, the consequences are consistent:
Decisions don’t get made. Consensus with 12 people is hard enough. With 25 or 30, it becomes nearly impossible in a two-day window. The retreat ends with broad themes instead of clear strategic priorities.
The session moves slowly. More people means more input on every topic. Discussions that should take 30 minutes take 90. The agenda falls behind by mid-morning and critical items get rushed or cut entirely.
Dominant voices take over. In a large group, three or four people do most of the talking. The rest disengage — not because they don’t have ideas, but because there’s no space to contribute. The plan ends up reflecting a few perspectives, not the full group.
Ownership gets diluted. When 30 people participate, nobody feels personally responsible for execution. Accountability diffuses across the group and the plan loses momentum within weeks.
A smaller, intentionally selected group produces better discussions, clearer decisions, and stronger commitment to execution. Every time.
The Right Group, Not the Biggest Group
Strategic planning works best when the people in the room were chosen because their perspective is essential — and when everyone who isn’t in the room still had a way to contribute. Focus groups, interviews, and surveys make that possible without compromising the quality of the retreat.
Choose your planning team early. Choose them deliberately. And if someone’s term is about to start or their perspective is critical but their schedule doesn’t allow two days — find another way to include their voice rather than skipping it entirely.
The plan is only as strong as the people who built it and the perspectives they had access to.
