Business Process Modeling Basics
Part of the Business Analyst Roadmap
In short
Ask five people how a leave request gets approved and you'll get five answers. Drawing the process turns those guesses into one picture everyone can point at and argue about.
Visually representing how a business process actually works — the sequence of steps, decisions, and handoffs — making an abstract workflow concrete enough to analyze and improve.
Think of it like this
The dabbawala system
A tiffin is picked up from a home, sorted at the station, carried by train, sorted again and delivered to an office desk. Each step has an owner and a handoff. Drawing that chain is process modelling: who does what, in what order, and where it can slip.
Watch it happen
The building blocks of any process
1/5Every process starts with a trigger: an employee submits a leave request.
The big ideas
What you need to know
Clear start and end
Name the trigger and the outcome first. If you can't say where the process starts and stops, the diagram will sprawl.
Who does each step
Every activity has an owner, a person, team or system. Missing owners are often where work gets stuck.
Decisions and exceptions
Show the yes and no paths. The 'no' paths are where most real complaints and rework live.
Model reality first
Draw how it really works today, workarounds included, before drawing how it should work.
Save yourself the pain
Common mistakes
Oops
Drawing the process from the policy manual alone.
Do this instead
Walk it with the people who do it. Their version, with workarounds, is the one you need to improve.
Oops
Cramming 60 boxes onto one page.
Do this instead
Keep the top level to about 5 to 15 steps. Break big steps into their own sub-process diagrams.
