FlowVisual

Simulate processes, find the bottleneck, prove the fix in euros.

FlowVisual is a desktop simulator for process consultants: model a process from elements, watch it run live, let a Monte-Carlo stress test expose the bottleneck, and prove the improvement in € and time via what-if — as a branded PDF for your proposal or business case. Ranges instead of false precision (5–10 min, not 7.5), probabilities instead of gut feel, every € figure with a P10–P90 band. Runs locally, no cloud, no sign-up — files on your own drive. Windows & macOS.

Most tools let you draw a process. FlowVisual lets you run it.

A flowchart just sits there. A real process breathes — work piles up at the slow step, the queue grows, the cost climbs. FlowVisual is a desktop simulator that makes that visible: you model the process from a few building blocks, hit play, and watch the workload flow through it in real time. Where it gets tight, the node fills up and turns from teal to red. That red node is your bottleneck — and now you can prove what fixing it is worth.

Your process, running live — fill is workload, colour is utilisation; the red node is the bottleneck

Find the breaking point — with probability, not gut feel

One click runs a Monte-Carlo stress test: hundreds of simulated days with realistic demand swings and peak spikes. Instead of one average that lies, you get the honest picture — how often each step is the binding constraint, its P90 utilisation, the spread of cycle time. The step that breaks first is ranked first. No more arguing about where the problem is.

Prove the fix in euros — with a confidence band

Change a number — add a person, automate a step, cut a service time — and the model rebalances instantly. Then see the payoff: Before vs. After in cycle time and in euros per year, every figure carried with a P10–P90 band so you never hand a CFO a false-precision number. That's the difference between "trust me" and "here's the math."

Model the whole landscape, not just one box

Real work doesn't live in a single diagram. Link processes so one feeds the next — when an upstream bottleneck throttles output, you watch the downstream process starve, live. Drill into any step to model its sub-process. The depth is there when you need it; the view stays clean when you don't.

Ranges, not false precision

A step doesn't take exactly 7.5 minutes — it takes 5 to 10. FlowVisual lets you say that, and the simulation carries that uncertainty all the way to the result. Every value can be tagged by where it came from, so it's always clear how much weight a number can hold. That honesty is what makes the output defensible in the room.

The deliverable does the selling

Export a branded PDF — your logo, the customer's letterhead, the € business case, the before/after, the process documentation. What your client keeps is sober, precise and decision-grade. The lively app is for you; the PDF is for them.

Fully local. No cloud, no sign-up.

Your process models never leave your machine. No account, no upload, no AI at runtime — files live on your own drive, local or a shared SharePoint folder. Nothing to clear with IT.

Who it's for

Process and management consultants, in-house optimisers and operations leads — anyone who has to walk into a room and defend "this change is worth €X" in front of people who will push back.

How it works

  1. Model your process from elements — or start from the built-in example.
  2. Run the stress test; find the bottleneck.
  3. Try a fix; watch it rebalance.
  4. Export the before/after business case as a branded PDF.

Questions & answers

Frequently asked.

Does FlowVisual run on Windows too?

Yes. On Windows, FlowVisual lives in the Microsoft Store — installed from there it skips the SmartScreen dialog and updates itself. If you don't use the Store, the same build is available as a signed direct installer here.
