What it means
Every process has a trigger, a series of steps with named owners, and a defined output. Invoice to cash starts when work is delivered and ends when the money is banked, passing through billing, approval, dispatch, chasing and reconciliation along the way.
Processes matter financially because their cost is driven by volume. A step that adds ten minutes costs almost nothing once, but adds over 16,000 hours a year across 100,000 transactions, so small inefficiencies scale into serious money.
In practice processes are documented as flowcharts and measured on three things: cycle time, cost per transaction, and the error or rework rate. Improvement usually comes from removing handovers and approvals rather than asking people to work faster.
Processes also carry risk, which is why auditors examine them. Segregation of duties, approval limits and reconciliation steps exist inside processes rather than in policy documents, and a process redesign that quietly removes a control can create a fraud opportunity nobody intended.
A nuance worth knowing is the difference between a process and a procedure. The process is the end-to-end flow across departments, while a procedure is the detailed instruction for one step within it, and confusing the two leads to teams perfecting their own step while the overall flow gets slower.
Written processes also protect a business against key-person dependency. When a single employee is the only person who knows how the month-end runs or how a large customer is invoiced, that knowledge is an operational risk rather than an asset.
In practice
Real-world examples.
Example
A housing association maps its repairs process and finds that a tenant's request passes through five people before an engineer is booked. Cutting it to two reduces the average wait from eight days to three. Complaint volumes drop sharply, which frees the customer service team for other work.
Example
A payroll bureau documents its month-end process after a key employee resigns. What existed only in that person's head becomes a checklist that a new starter can run within a fortnight.
Example
A car dealership times its handover process and discovers that preparing paperwork takes longer than the customer's test drive. Pre-filling the forms at the point of sale frees a sales day each week across the site. Customer satisfaction scores for the handover also improve, because buyers spend the time with the car instead of the paperwork.
Think of it
“Business process is how work gets done-the steps to complete a business activity.
Formula
Calculation
Annual process cost = annual volume x (minutes per transaction / 60) x fully loaded hourly cost.
A wholesaler processes 4,000 supplier invoices a month, each taking 30 minutes of accounts payable time at a fully loaded cost of $36 an hour. Cost per invoice is (30 / 60) x $36 = $18, so the monthly cost is 4,000 x $18 = $72,000 and the annual cost is 12 x $72,000 = $864,000. After introducing automated matching against purchase orders, handling time falls to 12 minutes, giving a cost per invoice of (12 / 60) x $36 = $7.20, a monthly cost of 4,000 x $7.20 = $28,800 and an annual cost of $345,600. The annual saving is $864,000 - $345,600 = $518,400.Case study
Seen in the real world.
Pellworth Medical Supplies is a fictional distributor used here as an illustrative case. Its finance team was permanently late closing the month, typically finishing on working day 12, and the delay meant managers received numbers that were already stale.
Mapping the close revealed 61 individual steps, of which 19 were waiting on someone else and 7 were duplicate checks that two different people performed on the same figures. Stock reconciliation alone accounted for four days because it began only after the warehouse finished a full manual count.
In this illustrative redesign Pellworth moved to rolling stock counts through the month, removed the duplicate checks and set hard cut-off times for expense claims. The close came down to working day 5, and the same team absorbed the acquisition of a second warehouse without extra hires.
Watch out
Common mistakes.
- Documenting the process as it is supposed to work rather than as people actually run it, which makes the map useless for finding waste.
- Automating a bad process, so the same unnecessary steps now happen faster and are harder to change.
- Measuring only the time each step takes and ignoring waiting time between steps, which is usually where most of the delay hides.
Questions
People also ask.
What is the difference between a process and a workflow?
In everyday use they overlap heavily, though workflow usually refers to the routing of a single item through a system while process describes the whole end-to-end activity.
Who should own a business process?
One named person with authority across every department the process crosses, because processes fail most often at the handovers between teams.
How do you decide which process to improve first?
Multiply the cost or time per transaction by the annual volume, and start with the largest number rather than the most irritating one.
