Which General Staff Member Prepares Incident Action Plans
If you've ever watched emergency responders coordinate during a wildfire, a hurricane response, or even a large-scale search and rescue operation, you've witnessed the Incident Command System in action. But it's the backbone of how emergency management works in the United States — and around the world. But here's something most people don't realize: behind every coordinated response, there's a document that makes it all possible. That document is called the Incident Action Plan, and someone specific is responsible for putting it together.
So who is it?
The answer is the Planning Section Chief — one of five general staff positions under the Incident Commander. This person owns the planning process from start to finish, and without their work, the rest of the response would essentially be operating in the dark And that's really what it comes down to..
Let me break down what that actually means, why it matters, and how it works in practice.
What Is an Incident Action Plan
An Incident Action Plan — often shortened to IAP — is the written document that guides all incident operations for a specific operational period. In plain English: it's the game plan for what everyone does, when they do it, and how they stay safe while doing it Took long enough..
No fluff here — just what actually works Worth keeping that in mind..
Think of it like this. You've got dozens — sometimes hundreds — of people responding to an emergency. Firefighters, law enforcement, paramedics, public works crews, volunteers. Every single one of them needs to know three things: what the objectives are, what their specific assignment is, and what hazards they need to watch out for. The IAP is where all of that comes together in one place.
Each IAP covers an operational period, which is typically 12 or 24 hours. When that period ends, a new IAP is developed for the next one. This cycle continues until the incident is closed And that's really what it comes down to. Still holds up..
Here's what you'll typically find inside an IAP:
- The incident objectives for that operational period
- Organizational assignments and resource lists
- Communications plan
- Medical plan
- Traffic plan
- Safety message and hazard analysis
- Maps and situational information
- Attachments specific to the incident
The whole point is coordination. Also, without a written plan, you get people working at cross-purposes, resources going where they're not needed, and safety information getting lost in the shuffle. The IAP is the glue that holds everything together.
Who Prepares the Incident Action Plan
This is where the General Staff structure comes into play.
In ICS, the Incident Commander is at the top. Below the Incident Commander are four (sometimes five) General Staff positions: Operations Section Chief, Planning Section Chief, Logistics Section Chief, and Finance/Administration Section Chief. Each has a specific role in the overall response.
The Planning Section Chief is the one tasked with preparing the Incident Action Plan. This isn't a shared responsibility or something that gets delegated to someone else — it's their primary function.
Here's what the Planning Section Chief does:
- Collects and displays all incident information
- Develops situation summaries and projections
- Tracks resources assigned to the incident
- Prepares the written IAP for each operational period
- Coordinates with all section chiefs to ensure the plan is realistic
- Maintains documentation related to the incident
The Planning Section Chief doesn't work alone, of course. Consider this: they lead a Planning Section that includes units like the Situation Unit, Resources Unit, Documentation Unit, and sometimes a Technical Specialist team. But at the end of the day, the Planning Section Chief is the one who signs off on the plan and presents it to the Incident Commander.
How the Planning Section Chief Fits Into the Bigger Picture
It's worth understanding how this role interacts with the other General Staff positions, because the IAP isn't created in a vacuum.
The Operations Section Chief is the one executing the response — they're managing all the tactical operations on the ground. They tell the Planning Section Chief what's actually feasible, what resources they have, and what they need to accomplish.
The Logistics Section Chief provides the resources, supplies, and support needed to carry out the plan. If the plan calls for additional engines, helicopters, or communication equipment, Logistics makes it happen.
The Finance/Administration Section Chief tracks costs, manages contracts, and handles administrative matters that might affect the plan No workaround needed..
The Planning Section Chief pulls input from all of these people, synthesizes it, and produces the IAP that everyone then follows. It's a coordinating role — and it requires staying calm under pressure while managing a lot of moving pieces The details matter here. No workaround needed..
Why the IAP Matters So Much
Here's the thing about emergency response: it's chaotic by nature. New information comes in every few minutes. Things change fast. And resources shift. Conditions on the ground evolve.
Without a written plan, you're relying on verbal instructions and memory. And in a complex incident with dozens of agencies involved, that simply doesn't work. Think about it: people miss things. Because of that, priorities get confused. Safety protocols fall through the cracks.
The IAP solves this in a few critical ways.
It creates a shared understanding. Everyone — from the Incident Commander down to the individual crew on the ground — is working from the same document. There's no ambiguity about what the priorities are.
It ensures accountability. When things go wrong, there's a written record of what was supposed to happen, who was assigned where, and what information was available at the time. This is crucial for both operational improvement and any subsequent review or investigation Turns out it matters..
It protects responders. The safety message included in every IAP isn't optional paperwork — it's how people know what hazards to watch for and how to stay safe. Skipping the planning process means skipping this critical safety information.
It enables coordination across agencies. When multiple agencies respond to an incident — which is common in large emergencies — the IAP provides a common framework. Everyone agrees to the plan, then everyone executes according to it. That's how you avoid the jurisdictional conflicts and communication breakdowns that have historically plagued major disasters.
How the IAP Is Developed
The process of creating an Incident Action Plan follows a fairly structured cycle, though it can compress or expand depending on the situation.
Step 1: Understand the Current Situation
The Planning Section starts by gathering all available information about the incident. What's the current status? What resources are on scene? Worth adding: what are the current conditions? This comes from the Situation Unit, which maintains current maps, status boards, and incident information It's one of those things that adds up..
Step 2: Identify Objectives
The Planning Section Chief participates in meetings with the Incident Commander and other General Staff to establish objectives for the upcoming operational period. These objectives should be specific, measurable, achievable, relevant, and time-bound — the SMART framework applies here.
Take this: an objective might be: "Complete evacuation of Zone 3 by 1800 hours" or "Establish a 500-foot fire break on the western flank by end of operational period."
Step 3: Develop the Plan
Once objectives are set, the Planning Section Chief works with the other sections to build the plan. Which means logistics confirms resource availability. Operations provides tactical assignments. And safety identifies hazards. The Planning Section pulls all of this together into the written document It's one of those things that adds up..
Step 4: Brief and Approve
The IAP is presented to the Incident Commander for approval. Consider this: once approved, it's distributed to all section chiefs and, through them, to all personnel. A briefing is typically held where the plan is explained to all key personnel.
Step 5: Execute and Monitor
During the operational period, the plan is put into action. The Planning Section continues to monitor the situation, track resources, and gather information for the next planning cycle.
Step 6: Evaluate and Repeat
At the end of the operational period, the cycle begins again. And what worked? What didn't? What changed? The next IAP reflects the updated situation Worth keeping that in mind. Simple as that..
This cycle — sometimes called the "planning cycle" — continues for the duration of the incident.
Common Mistakes People Make
Having been around emergency management for a while, I've seen some recurring issues when it comes to the IAP process. Here's what tends to go wrong That's the part that actually makes a difference..
Treating the IAP as a checkbox. Some incidents — especially smaller ones — can feel like the planning process is just bureaucratic busywork. But skipping or rushing the IAP is a mistake. Even a simple incident benefits from the discipline of written objectives and assignments. The plan doesn't have to be 20 pages long, but it should exist.
Not involving all sections early enough. The Planning Section Chief can't develop a realistic plan in a vacuum. If Operations isn't consulted on what's actually feasible, you end up with a plan that looks good on paper but falls apart in practice. Early and continuous coordination is essential.
Letting the plan become outdated. In fast-moving incidents, the situation can change dramatically within hours. Holding too tightly to a plan that's no longer accurate creates danger. Good planning means building in flexibility and being willing to revise when conditions change.
Weak safety messages. The safety portion of the IAP is sometimes treated as an afterthought. Big mistake. This is how responders know what hazards they're walking into. A vague or incomplete safety message puts people at risk Less friction, more output..
Not documenting changes. When the plan changes during an operational period, those changes need to be documented and communicated. Verbal changes that aren't recorded create confusion and can lead to accountability problems later The details matter here..
Practical Tips for Effective IAP Development
If you're involved in the planning process — whether as the Planning Section Chief or in a supporting role — here are some things that actually make a difference Most people skip this — try not to..
Start early. Don't wait until the last minute to begin the planning cycle. The earlier you start gathering information and coordinating with sections, the better the final plan will be Which is the point..
Keep it readable. The IAP needs to be clear and usable, especially for field personnel who may be reading it in difficult conditions. Use plain language, clear formatting, and avoid unnecessary jargon.
Be specific with objectives. Vague objectives like "manage the incident effectively" don't help anyone. Make objectives concrete so everyone knows exactly what success looks like Small thing, real impact. Turns out it matters..
Build in check-ins. Don't wait until the end of the operational period to assess whether the plan is working. Regular check-ins with section chiefs during the period help identify problems early Took long enough..
Use the planning meeting structure. ICS provides a recommended framework for the planning meeting — use it. Having a consistent structure keeps everyone on the same page and ensures nothing gets missed Small thing, real impact..
Prioritize the safety message. Take the time to identify real hazards and communicate them clearly. This is one of the most important parts of the entire document Turns out it matters..
Frequently Asked Questions
Who is responsible for the Incident Action Plan in ICS?
The Planning Section Chief is responsible for preparing the Incident Action Plan. This is one of their primary duties within the General Staff structure But it adds up..
Can someone other than the Planning Section Chief prepare the IAP?
In very small incidents where a full Planning Section isn't established, the Planning Section Chief role might be combined with another position, or the Incident Commander might handle planning functions directly. But in any case, the responsibility for the IAP rests with whoever is performing the planning function — there's no getting around it.
How often is an IAP prepared?
An IAP is prepared for each operational period. Operational periods are typically 12 or 24 hours, though they can be shorter in fast-moving situations. A new IAP is developed each time the operational period changes.
What happens if there's no written IAP?
Operating without a written IAP is generally considered poor practice and increases the risk of coordination failures, communication breakdowns, and safety issues. For incidents involving multiple agencies or jurisdictions, a written IAP is often required by policy or protocol That's the part that actually makes a difference..
Does every incident need an IAP?
Technically, yes — even small incidents benefit from a written plan. Even so, the complexity and detail of the IAP should be proportional to the incident. A small, single-resource incident might have a very simple IAP, while a major disaster will have an extensive, detailed plan.
The Bottom Line
The Planning Section Chief is the general staff member responsible for preparing the Incident Action Plan. It's one of the most important roles in the entire ICS structure, because the IAP is what turns a group of responders into a coordinated team Simple, but easy to overlook..
Without the planning function, you'd have people acting independently, objectives would be unclear, and safety information would be inconsistent. The Planning Section Chief brings order to chaos — and that's exactly what emergency management is all about.
Whether you're new to ICS or have been working in emergency response for years, understanding this role helps you appreciate the system as a whole. Every well-coordinated response you've seen likely started with a solid IAP — and someone in the Planning Section made that happen Worth keeping that in mind. Still holds up..
