What it means
Every business process, from hiring a supplier to closing the books, follows some path, whether anyone has written it down or not. A workflow makes that path explicit by showing each task, who is responsible for it, what must happen before the next step and where decisions are taken.
It can be drawn as a flowchart or built directly into software. The commercial benefit is control and speed together.
When everyone knows the route, work does not stall because nobody is sure who should act next. Approvals can also be built in, so that a payment above a set amount automatically goes to a more senior person.
Finance teams use workflows constantly. An expense claim moves from employee to manager to accounts payable, a purchase order moves from requester to budget holder to buyer, and a month-end close moves through reconciliations, journals and review.
Each of these has steps that must happen in a set order and sign-offs that must be recorded. Automation takes this further, because software can route items, send reminders and keep a log of who did what and when.
That log is valuable for internal control and for auditors, who want evidence that required approvals took place. It also shows where work gets stuck, which helps managers find bottlenecks (points where work queues up waiting for a step).
The nuance is that automating a poor process simply makes the poor process faster. It is worth simplifying and removing unnecessary steps before building the workflow into a system.
Too many approval layers can also slow the business without adding real control. Measuring a workflow is what turns it from a diagram into a management tool.
Useful measures include the time each step takes, the share of items that need rework and the number waiting at any moment. Reviewing these figures monthly shows whether a change has really helped, and gives the finance team evidence when asking for investment in better systems.
In practice
Real-world examples.
Example
A mid-sized retailer builds an approval workflow for supplier invoices. Invoices under $1,000 go to the department head, those between $1,000 and $10,000 also go to the finance manager, and anything higher goes to the CFO. Approval time falls from nine days to three.
Example
A software company uses a workflow for new customer contracts. Sales submits the deal, legal reviews the terms, finance checks the credit and the contract is released only when all three have signed off. Nothing is missed because the system will not allow a step to be skipped.
Example
A hospital group designs a workflow for staff expense claims with receipts uploaded from a phone. Claims that match policy are approved automatically, and only unusual ones go to a manager, which saves hours each week.
Formula
Calculation
Process cycle efficiency = value-adding time / total elapsed time
Suppose an invoice takes 10 working days to be paid after arrival, which is 80 working hours. The actual hands-on work, such as entering, matching and approving, takes 2 hours in total. Process cycle efficiency = 2 / 80 = 0.025, or 2.5%. If a redesigned workflow cuts elapsed time to 20 hours with the same 2 hours of work, efficiency rises to 2 / 20 = 10%.Case study
Seen in the real world.
Marlow & Finch Distribution is an illustrative, fictional wholesaler that processed about 1,500 supplier invoices a month. Invoices arrived by email and post, were passed round the office in folders and were often paid late, which cost the company early payment discounts.
The finance manager mapped the existing process and found it had eleven steps, four of which were duplicate checks. She designed a simpler six-step workflow in the accounting software, with automatic matching to purchase orders and approval routing by amount.
After three months, the average time to approve an invoice fell from 12 days to 4. The company captured early payment discounts worth about $2,500 a month, and the illustrative lesson is that fixing the process came before buying the technology.
Watch out
Common mistakes.
- Automating a messy process without first simplifying it, which locks in the waste and makes later changes more expensive.
- Adding approval layers for every small item, which slows the business and makes people look for ways around the system.
- Failing to name an owner for the workflow, so nobody updates it when the business changes.
Questions
People also ask.
What is the difference between a workflow and a process?
A process is the overall way work gets done, while a workflow is the specific sequence of steps, roles and hand-offs that carries it out.
Does a workflow need software?
No, a written checklist can be a workflow, although software makes routing, reminders and audit trails easier.
How does a workflow help internal control?
It sets who can do and approve each step, and it records evidence, which supports segregation of duties and audits.
