Expected time6 h 14,01 min

Expected cost1.219.679,49 VND

P90 (simulated)7 h 20 min

The diagram and figures above were produced by the tool itself from the sample process P2P — Mua hàng đến thanh toán — 17 steps, 6 scenarios. Not a staged screenshot.

Three numbers you get the moment you upload a file

Average per case 6 h 14,01 min Rework and per-branch probability are already included — not a raw sum of every step (1 d 1 h 55 min).

Cost per case 1.219.679,49 VND Parallel branches add up in full, because every branch spends money even when they run at the same time.

A safe commitment point 7 h 20 min P90 across 2000 simulated runs. Commit to the average and nearly half your cases will be late.

Edit the table and the diagram follows instantly

The step table sits right under the diagram. Change a time, add a cost, adjust a branch probability — the diagram, the critical path and every metric recalculate within half a second. Nothing is written until you press save, so experiment freely.

Edit in the table or straight in the XML, whichever you prefer
Drag steps into a clearer order
Every save is a version you can roll back to

See at a glance which steps are heavy and which get reworked

Besides the proper BPMN diagram there is a network view: circles sized by time (or by money), an orange badge showing how often a step has to run again, and dashed edges for loop-backs.

Thẩm định 1,54× Đạt yêu cầu? 1,54×

In this sample process 35% of cases need more documents, so the appraisal step runs on average 1,54 times — usually the cheapest place to improve.

Know what SLA you can safely commit to

You cannot promise a customer an average. The tool runs 2000 simulated runs, each picking branches at exactly the probabilities you declared and repeating rework for real, then gives you the full distribution.

No number appears out of thin air

Every calculation is written out in standard mathematical notation, with a worked example you can check by hand. If something is wrong, you can point at exactly where.

T_AND = max_j T_j Parallel branches: only the slowest one sets the time

C_AND = Σ_j C_j But cost adds up across every branch

E[T_XOR] = Σ p_i·T_i Branching: a probability-weighted average

n^T(I − P) = e₀^T Rework solved with a Markov chain — every loop counted

What it is for

📋

Quantify where you are today

Replace “this process is slow” with “each case takes 6 h 14,01 min, of which 5 h 5 min is the fastest case”.

🎯

Improve the right step

The critical path shows which step is worth shortening. Shortening a step off the critical path leaves the total unchanged.

💰

Prove the improvement in money

Duplicate the process, edit the copy, compare the two numbers. The difference times your monthly case volume is the number that goes into the proposal.

🤝

SLAs backed by evidence

Base it on P90 rather than the average, so the promise to your customer holds in most cases.

🔧

The tool builds the diagram

From the log the tool finds the steps, the order they truly happen in, and the rework loops the process on paper usually leaves out.

⏱

Separate working time from waiting time

With an end column you learn how long each step actually takes and how long the case sits waiting — waiting is usually the larger share.
