The costs of maintaining quality

1. Inspection and testing costs: inspectors have to be paid, testing equipment has to be bought and maintained, and output waits to be checked instead of being sold.
2. Staff training: employees have to be taught the standard and how to check their own work against it, which costs the trainer's time and the output lost while they are away from the job.
   1. Training is a repeated cost rather than a one-off, because every new starter needs it and staff turnover in shops and restaurants is high.
3. Better materials and better suppliers: higher-grade inputs and dependable suppliers charge more per unit, so the cost of making each item rises before anything has been sold.
4. Slower production: checking at each stage means fewer units leave the factory each hour, so rent and machinery are spread over less output and the cost of each unit rises.
5. Product recalls and compensation: when quality fails anyway, the business must trace and contact buyers, replace or repair goods already sold, and may have to compensate customers or a retailer for sales lost while the product is off the shelves.

The benefits of maintaining quality

1. Additional sales: a product that does what it promises sells more, because satisfied customers buy again and recommend it to people the business never advertised to.
2. Repeat custom and loyalty: keeping an existing customer costs far less than advertising to find a new one, and steady repeat orders let the business plan production and staffing with confidence.
3. Image and reputation: a name for reliability attracts buyers who have never tried the product, and large retailers prefer to stock brands their shoppers already trust.
4. A higher price: buyers will pay more for something they expect to last, which is how Dyson sells vacuum cleaners at several hundred pounds against rivals under £50, so the money spent on engineering and testing returns as a wider margin.
5. Less waste and rework: getting the work right first time means fewer items scrapped, reworked or refunded, so part of the spending on quality pays for itself in lower costs.

Quality in the provision of services

1. A service is produced while the customer is present, so it cannot be inspected and put right before they experience it.
2. The spending therefore goes on people rather than testing equipment: training, written procedures, supervision, and enough staff to give each customer proper attention.
3. Consistency between staff and between branches is the hard part, because the same chain can feel excellent in one town and careless in the next.
4. Putting a service failure right costs a refund or a free repeat, and the customer has already lived through the bad experience, which no refund erases.

Quality problems as a business grows

1. More sites and more staff: the owner can no longer watch every job, so standards drift unless they are written down, trained and checked by somebody else.
2. Outsourcing: paying another business to make the product or handle part of the work puts quality in somebody else's hands, and their priority is their own costs.
   1. A supplier that quietly swaps to cheaper materials protects its own margin, while the complaints land on the brand whose name is on the box.
3. Franchising: each franchisee runs their own outlet, so the brand depends on people the franchisor does not employ and cannot supervise day to day.
   1. This is why franchise agreements set out exactly which ingredients, suppliers and procedures must be used, backed up by regular inspection visits.

Weighing the costs against the benefits

1. Nearly all of the cost is paid now while the extra sales and the reputation build over years, which is a real problem for a business that is short of cash today.
2. The spending is repaid most clearly where a failure would be dangerous or highly public, such as food, medicines, cars or childcare, and where customers choose on trust rather than on price alone.
3. Growth usually pushes the cost up, because work the owner once checked personally now has to be covered by written standards, supplier audits and inspection visits.
