Process Map vs Flowchart: What's the Difference?
People use the two terms interchangeably, and they do overlap: most process maps are drawn with flowchart shapes. The difference is the question each one answers. A flowchart answers "what happens next?" A process map also answers "who does it, with what, and where does the work get stuck?" Here is how to tell them apart, with one process drawn both ways.

The short answer
| Flowchart | Process map | |
|---|---|---|
| Main question | What happens next, and under which condition? | Who does each step, with what, and where does work change hands? |
| Scope | Anything with steps: an algorithm, a login screen, a task one person does | A business process, from a trigger (a request, an order) to an outcome |
| Shapes | Terminal, process, decision, input/output, arrows | The same shapes, plus lanes for roles and often documents and systems |
| Extra details | Rarely | Roles, inputs and outputs, systems, time per step, pain points |
| Common forms | Basic flowchart, program flowchart | High-level map (SIPOC), detailed map, swimlane map, value stream map |
| Typical users | Students, developers, anyone explaining logic | Business analysts, operations and HR managers, quality and Lean teams |
In one sentence: every process map is a kind of flowchart, but not every flowchart is a process map. A flowchart of a sorting algorithm is not a process map. A swimlane diagram of how invoices get approved is both.
What a flowchart is
A flowchart shows the steps of a process in order, using standard shapes: an oval for start and end, a rectangle for each action, a diamond for each yes/no decision, and arrows for the order. It focuses on logic: what happens, in what sequence, and which path is taken under which condition. Our guide to flowchart symbols and their meanings covers every shape.
Flowcharts work for almost anything with steps: a password check with three attempts, an ATM withdrawal, a troubleshooting guide. Nothing in the format says who performs a step, how long it takes, or which system it happens in.
Example: A flowchart of employee onboarding: clear steps and one decision, but nothing about who does each step.
What a process map is
A process map documents how work actually gets done in an organization. It starts with a trigger (a customer places an order, an employee requests time off) and ends with an outcome (the order is delivered, the leave is recorded). Along the way it records what a manager or analyst needs to run or improve the process:
- Roles: which team or job does each step, usually shown as swimlanes.
- Inputs and outputs: the form, request or document each step needs and produces.
- Systems: the ERP, CRM, ticketing tool or spreadsheet where the step happens.
- Handoffs: every point where work moves from one role to another.
- Measures: time per step, waiting time, volume, rework rate.
- Pain points: where cases wait, loop back or get lost.
Example: A purchase order as a swimlane process map: requester, manager, finance and vendor each get a lane, so every handoff is visible.
Types of process maps
| Type | What it shows | Use it for |
|---|---|---|
| High-level map (SIPOC) | Suppliers, Inputs, Process (about five to seven big steps), Outputs, Customers | Agreeing on scope before detailed mapping |
| Detailed process map | Every step and decision, often with inputs, outputs and systems | Training, SOPs, finding where errors come from |
| Swimlane (cross-functional) map | Steps arranged in lanes by role or team | Processes that cross departments; finding handoff delays |
| Value stream map | Steps with process time, wait time and inventory between them (from Lean) | Cutting lead time in manufacturing and operations |
Teams also separate the current-state ("as-is") map, which shows how the process runs today, from the future-state ("to-be") map, which shows the improved version. Draw the current state first, honestly, including the workarounds people use.
One process, drawn both ways
Take a purchase order. As a flowchart it reads: Raise request → Approved? → Check budget → Create purchase order → Deliver goods → Send invoice → Pay invoice. That is enough to explain the logic to someone new.
As a process map, the same steps go into four lanes: Requester, Manager, Finance and Vendor. Now you can see that the work changes hands four times, that Finance owns three of the seven steps, and that payment waits on the vendor's invoice. Add the inputs (purchase request, budget report, invoice), the system (your ERP or accounting tool) and the usual time for each step, and you have a map you can use to find the delay.
Tip: If you catch yourself writing "(Finance)" or "(Manager)" inside the boxes of a flowchart, you need lanes. Switch to a swimlane process map.
When to use which
| You want to… | Use |
|---|---|
| Explain an algorithm or a decision rule | Flowchart |
| Write a troubleshooting guide or a short task for one person | Flowchart |
| Show who is responsible for each step across teams | Swimlane process map |
| Write or update an SOP | Detailed or swimlane process map |
| Agree on the scope of an improvement project | SIPOC |
| Cut lead time in an operation | Value stream map |
| Show parallel work, timers or messages between companies | BPMN (see swimlane vs BPMN) |
How to turn a flowchart into a process map
- Set the boundaries. Write down the trigger that starts the process and the outcome that ends it.
- Add a lane for each role and move every step into the lane of the role that does it.
- Mark the handoffs. Every arrow that crosses a lane is a handoff. Note what is handed over: a form, an approval, an email.
- Add inputs, outputs and systems to the steps where they matter.
- Add numbers. The usual time per step, how often each decision goes each way, and how many cases arrive per week.
- Walk it with the people who do the work. At every decision and handoff, ask "what really happens when…?"
Common mistakes
- Mapping how the process should work instead of how it does work. Talk to the people doing it, or check the system's history.
- Too much detail too early. Start with 5–15 steps and zoom in only where the problem is.
- Naming lanes after people instead of roles. People change jobs; roles stay.
- Decisions with unlabeled branches, or "No" branches that lead nowhere.
- Drawing the map and never using it. A process map should feed an SOP, training or an improvement project.
From process map to SOP and simulation
In AI Flowchart you can describe a process in plain English and get an editable swimlane process map. Because the map knows the roles and the order of the steps, you can press 📄 SOP to turn it into a standard operating procedure with a RACI matrix, or give each step a time and press ⏱ Simulate to see which team becomes the bottleneck.

Frequently asked questions
Is a process map the same as a flowchart?
Not quite. A process map is a flowchart used to document a business process, usually with roles (swimlanes), inputs, outputs and systems added. A flowchart can show any sequence of steps, including an algorithm, with no owners at all.
Is a swimlane diagram a process map?
Yes. A swimlane (cross-functional) diagram is one of the most common kinds of process map, because the lanes show who does each step and where work is handed over.
What are the main types of process maps?
High-level maps such as SIPOC, detailed process maps, swimlane (cross-functional) maps and value stream maps. Each one shows a different level of detail for a different purpose.
What should a process map include?
A clear start (the trigger) and end (the outcome), every step and decision in order, the role responsible for each step, and the handoffs between roles. Add inputs, outputs, systems and times when you plan to improve the process.
Should I use a process map or a flowchart for an SOP?
A process map, usually a swimlane, because an SOP has to say who does each step. The map becomes the backbone of the SOP, and each box becomes a numbered step.
