What does customization mean?
Customization is the process of modifying a product, service, or system so that it better suits the needs, tastes, or requirements of a particular individual or group. It is most often discussed in commercial and technological settings — think of tailored clothing, configurable cars, personalized marketing, or software whose settings can be adjusted to fit a user's workflow. The word carries a broadly positive connotation, implying attention to detail, customer care, and flexibility, and it is frequently set against its opposite, standardization, which emphasizes uniformity and mass production. A closely related term is personalization, which stresses individual identity rather than functional adjustment; in practice the two overlap considerably. The related verb is customize, meaning to make such modifications. Economists and manufacturers also speak of 'mass customization', a modern approach that combines the efficiency of large-scale production with the appeal of individually tailored goods, making customization one of the defining expectations of contemporary consumers.
nounThe action or process of modifying something to suit a particular person, task, or purpose; the state of being customized.
- The act or process of modifying a product, service, or system to meet an individual's or group's specific needs or preferences.
- A feature or option that allows such modification (e.g. in software: 'the customization panel').

"The software's deep customization lets administrators tailor every workflow to their organization's needs."
The plural refers to multiple instances or types of modification; it is far less common than the singular, which is usually treated as an uncountable process noun.
"Each of the three customizations added several hundred dollars to the vehicle's price."
Every time you pick a phone case, you're participating in 'mass customization' — a term economists coined to describe making millions of unique products without losing the efficiency of the assembly line.

Etymology of customization
Customization derives from the noun custom, which entered English via Old French costume from Latin consuetudinem, meaning habit or usage, itself rooted in consuescere, 'to accustom'. The verb customize arose in American English, first attested around the mid-20th century in advertising and manufacturing contexts, and customization formed directly from it using the Latinate -ization suffix that marks nouns of process or action. Cognates sharing the same Latin root include costume, customary, accustom, and customer.
