Time, cost, and quality will affect a product or service because the end product or service is only as good as the elements used in producing them. The idiom "garbage in, garbage out" can be applied here. According to the Oxford Languages dictionary, this means, "incorrect or poor quality input will always produce faulty output."
When production is designed to leverage high-quality work and higher-quality components, the end product benefits. Conversely, when insufficient time is allotted to the production process and less costly components are substituted, the results generally are apparent in that the end product suffers.
For instance, when purchasing sheets, thread count is an important factor. Thread counts of 400 to 700 are generally considered to produce the most comfortable sheets, while lower thread counts of 200 to 300 usually are considered to be less comfortable to sleep on. The cost of the lower-thread-count sheets is likely to be lower, but the quality is also likely to be lower.
When purchasing cashmere, it is important to note the inputs used to manufacture the product. Cashmere is a fine hair which therefore benefits from a higher strength in the twisted thread. When purchasing sweaters and other items produced of cashmere, the higher-quality items are made of two-ply quantity thread, because single-ply cashmere is generally considered to be less durable. A manufacturer can save money by using a single ply in producing the sweater, but the sweater is not considered to be as good as one produced using a two-ply process.
The quality of a service also benefits from the time, cost, and quality involved. For instance, if a restaurant hires a single wait staffer to be responsible for all tables, patrons at each individual table will not get the same service than if the restaurant had hired multiple servers. The restaurant operator will save money, but the quality of service will be hurt.
