quality assurance
Quality assurance is the habit of checking your work before the customer does, so complaints go down and trust goes up.
In plain English
Aunty Ngozi sells zobo and chin chin at a corner shop in Yaba, and one harmattan season, three customers in one week complained that the zobo tasted different. She could have shrugged it off as bad luck, but instead she went back to her recipe, checked her hibiscus supplier, and realised the batch was weaker than usual. That single act, checking before the next customer complained, is quality assurance.
Quality assurance is not the same as quality control. Quality control catches the bad batch after it is made. Quality assurance is the whole system that stops the bad batch from happening in the first place, the recipe you follow every time, the supplier you vet, the taste test before you sell.
In business, this shows up everywhere. A tailor in Aba who measures twice before cutting fabric is doing quality assurance. A software company in Yaba that tests an app before it goes live is doing the same thing, just with code instead of cloth. In the United Kingdom, a food business selling jollof at a market stall has to follow food safety standards set by the local council, and that regular checking, cleaning, and record keeping is quality assurance too.
For someone in the diaspora sending money home to fund a small business, this matters more than it seems. You are not there to taste the soup or check the fabric yourself, so you are trusting that whoever runs the business day to day has a system in place. Asking about that system, even casually, is one way to protect your investment from a distance.
Quality assurance is calmly the difference between a business that grows because people trust it and one that struggles because every sale feels like a gamble for the customer.
A bakery in Lagos loses ₦150,000 worth of bread in one month to complaints and returns. After introducing a simple checklist, checking oven temperature, ingredient freshness, and packaging before every batch leaves, returns drop to almost zero within two months.
Questions people ask
Is quality assurance only for big companies with lots of staff?
No. Even a one person business can have quality assurance, it can be as simple as a checklist you follow every time before you sell or deliver something, so nothing depends on memory alone.
What is the real difference between quality assurance and quality control?
Quality assurance is the system that prevents mistakes before they happen, like a recipe or a process. Quality control is the inspection that catches mistakes after the product is made, like tasting the soup before it leaves the kitchen.
How do I start building quality assurance into my small business?
Write down exactly how you do the thing that matters most, whether that is baking bread or writing code, then check your work against that written standard every single time, more than when you remember.
