In many small businesses there is a person who simply knows. Which supplier invoices can be paid without a second look. Which discount a long-standing customer is allowed. How much a branch manager can spend on a repair before it needs sign-off. None of this is written down. It lives in the head of the owner or the finance lead, and staff learn it the way you learn a local shortcut: by getting it wrong once.
This piece looks at why decision rights, meaning who is allowed to decide what and within what limits, work better when they are recorded in the system than when they are carried by one person's memory. It is a hypothesis built from general research on control and role clarity, not a finding about a specific South African business.
What a decision right is
A decision right is the answer to a simple question: for this kind of choice, who decides, and what are the limits? A purchase of R800 for printer toner. A refund to a customer who received the wrong item. An extension of payment terms to a client who is struggling. In each case someone in the business has to say yes or no, and the person asking needs to know who that is and how much room they have.
Management practitioners often use a responsibility matrix such as RACI, which sets out who is responsible, accountable, consulted and informed for each activity. The tool is not the point. What matters is the habit it encourages: naming the decision, naming the owner and making that visible to everyone who needs it.
When decision rights live only in someone's head, three things happen. People cannot tell what they are allowed to do. They ask the person who knows, even for small matters. And the answer they get depends on the day, the mood and how much that person remembers of the last time.
The human tax: autonomy
The cost to staff is a loss of autonomy, and it is a particular kind. It is not that they are told what to do. It is that they cannot find out how far their own judgement is allowed to go. The UK Health and Safety Executive's management standards for work-related stress identify control, how much say people have in the way they do their work, as a core condition of a healthy workplace. The related standard on role asks whether people understand what is expected of them and whether the limits of their authority are clear.
The World Health Organization's guidance on mental health at work lists unclear job roles and low job control among the working conditions that can pose a risk to mental health. A person who must guess where their authority ends, and who is occasionally corrected for guessing wrong, learns to stop guessing.
That has a flip side that is easy to miss. An employee who learns to ask about everything is not necessarily timid. They are responding sensibly to a system in which unrecorded rules punish initiative. The related piece on the employee who needs permission for every small fix describes the daily effect.
An illustrative case
Consider an illustrative example, not a real case: a Cape Town building supplies company with three branches and an owner who still approves most things. A branch manager needs to replace a delivery truck's tyre before a morning run. He phones the owner, who is at a wedding. The owner remembers saying "anything under R5,000 is fine" at a meeting in March, but cannot recall whether that applied to vehicles, and says to wait.
The truck runs late. Two customers on the roof of a half-finished house wait for roofing sheets. The branch manager knows what he should have done and is almost sure the owner would have agreed. What he lacks is any record of it. The next time, he spends the money and says nothing, and a month later he is questioned about it at a review.
No one acted badly. The decision right existed, but only as a half-remembered conversation.
Why a system is a better home
A system does not have a bad day. It does not forget what was agreed in March. More usefully, it can show the same rule to everyone at the moment they need it. There are several forms this can take, and none requires expensive software:
- Approval limits in the accounting or purchasing system, set by role, so that a branch manager can commit up to a stated amount and the system routes anything larger.
- A written authority schedule, one page, listing the common decisions and who may take them.
- Defaults in workflow tools, so that routine requests are approved or routed automatically according to the rule.
- A log of exceptions, so that when a rule is overridden the reason is recorded.
Segregation of duties, the accounting principle that no single person should be able to start, approve and conceal a transaction, is an example of a decision right that systems enforce better than memory does. It protects the business, and it also protects the individual, because the system, not a person's suspicion, shows that the process was followed.
The guidance on why approval processes become bottlenecks explains what happens when every request is routed to the same person, and how to make ownership clear at every stage is a practical way to begin.
What could realistically change
- List the twenty most common decisions. Ask staff what they most often ask permission for. That list is more reliable than anything the owner can recall.
- Set a limit for each, and a name. Specify the amount, the conditions and the person. Where possible, choose a limit high enough that most requests need no escalation.
- Put it where the work happens. Embed limits in the purchasing or approvals tool, or at minimum in a one-page document that everyone can find.
- Review after a quarter. Look at what was escalated, what was overridden and what was never used. Adjust the limits.
- Let the owner be the exception route, not the default. The article on why clear ownership gives people room to decide describes how this shifts behaviour, and the manager who can't act without the founder shows what happens without it.
The business outcome
Decisions that sit within recorded limits happen faster. Staff do not wait for an answer they already have the authority to give, and owners are interrupted less. The business becomes more predictable for customers, who get consistent answers regardless of who they speak to. For a business under POPIA, the same discipline applies to access to personal information: who may see or change customer data is also a decision right, and being able to show that it is controlled and recorded is part of demonstrating responsible handling.
It also makes the business easier to audit. When a bookkeeper or external accountant asks why a payment was made, "the branch manager approved it within his R5,000 limit" is a complete answer. "The owner told someone" is not.
The human dividend
The dividend is autonomy together with predictability. People know how far their judgement may go, and the answer does not change with the day. The owner, in turn, can trust that decisions are being made within limits they set, and is not the single point through which every choice must pass. Most people find that clarity, once they have it, is a relief and not a restriction.
The trade-offs
- Rules can be too rigid. A limit that seems sensible will sometimes be wrong for a particular case, and staff need a route for exceptions.
- Owners lose some visibility. Letting go of small approvals means seeing fewer of them. Regular summaries can replace individual sign-offs.
- Writing it down is uncomfortable. It forces the owner to say out loud rules they have been applying loosely, and sometimes to find that they disagree with themselves.
- Limits go stale. Prices change and inflation erodes fixed amounts, so the schedule needs a regular review.
- Systems add admin. Configuring approval limits takes setup time, and badly designed ones create their own queues.
Why it matters
When decision rights live in one person's head, everyone else has to guess, and guessing slowly teaches capable people to stop trying. Recording who may decide what, and within which limits, does not remove judgement from the business. It gives judgement a place to operate, and gives the owner a way to trust it.
