D. A. Collier suggests improving the process of service quality management by
the help of service quality performance standards, because they are the key
parameters for finding facility layout (Collier, 1987, p. 45–46). He presents the idea,
that accordance to monitoring and control of service quality, there is a possibility to
find general approaches of service quality management through some key points: 1) a
service is a facility, process, equipment and job; 2) improvement of staff
competences; 3) structure of service systems and procedures; 4) external
communication (Collier, 1990, p. 238).
