Significance of Service quality is very important for the success of a service company :
1. To win credibility & get repeat customers : If a company offers quality service consistently, It enjoys repeat business, i.e., customers visit it repeatedly. They may even refer it to their friends & relatives and provide positive word-of-mouth publicity to the quality service offered by the company.
2. To charge premium price : When a company offers superior quality service, compared to its competitors, customers who value quality will always prefer this company to other players in the market. So, the company will be in a position to charge a premium price from customers.
According to Berry & A Parasuraman, service quality is determined by customers using various criteria like credibility, security, access, communications, tangibles, responsiveness, reliability, competence, courtesy, tangibles, understanding, etc. Gronoos also suggested another list of criteria as professionalism & skills, attitude & behaviour, accessibility & flexibility, reliability & trustworthiness, reputation & credibility, and recovery. Since some of these factors are similar or overlapping, the authors have consolidated these into five distinct dimensions,
These dimensions represent how consumers organise information about service quality in their minds. These five dimensions were found relevant for banking, insurance, appliances repair, & maintenance, securities brokerage, long distance tele-service, auto repair service, & others. The dimensions are also applicable to retail & business services. This can be logically extended to internal services as well.
