Block diagram - Gap model of service quality

"Dimensions of service quality.
A customer's expectation of a particular service is determined by factors such as recommendations, personal needs and past experiences. The expected service and the perceived service sometimes may not be equal, thus leaving a gap. The service quality model or the ‘GAP model’ developed by a group of authors- Parasuraman, Zeithaml and Berry at Texas and North Carolina in 1985 , highlights the main requirements for delivering high service quality. It identifies five ‘gaps’ that cause unsuccessful delivery. Customers generally have a tendency to compare the service they 'experience' with the service they 'expect' . If the experience does not match the expectation , there arises a gap. Ten determinants that may influence the appearance of a gap were described by Parasuraman, Zeithaml and Berry. in the SERVQUAL model: reliability, responsiveness, competence, access, courtesy, communication, credibility, security, understanding the customer and tangibles.
Later, the determinants were reduced to five: tangibles; reliability; responsiveness; service assurance and empathy in the so called RATER model." [Service quality. Wikipedia]

"The dichotomy between physical goods and intangible services is an oversimplification; these are not discrete categories. Most business theorists see a continuum with pure service at one endpoint and pure commodity goods at the other endpoint. Most products fall between these two extremes. Goods are normally structural and can be transferred in an instant while services are delivered over a period of time. Goods can be returned while a service once delivered cannot. Goods are not always tangible and may be virtual." [Goods and services. Wikipedia]

"A business process or business method is a collection of related, structured activities or tasks that produce a specific service or product (serve a particular goal) for a particular customer or customers. It often can be visualized with a flowchart as a sequence of activities with interleaving decision points or with a Process Matrix as a sequence of activities with relevance rules based on data in the process. ...
There are three types of business processes:
(1) Management processes, the processes that govern the operation of a system. Typical management processes include "corporate governance" and "strategic management".
(2) Operational processes, processes that constitute the core business and create the primary value stream. Typical operational processes are purchasing, manufacturing, advertising and marketing, and sales.

The ... improvement areas are equally applicable to policies, processes and detailed procedures (sub-processes/ tasks). There is a cascading effect of improvements made at a higher level on those made at a lower level.
For instance, if a recommendation to replace a given policy with a better one is made with proper justification and accepted in principle by business process owners, then corresponding changes in the consequent processes and procedures will follow naturally in order to enable implementation of the policies" [Business process.

"Directory services are a great way of providing information that can be fre-
quently retrieved and searched on in a hierarchical way. ... Well, there’s no reason that you can’t create a directory service that’s actually a phone book. Imagine that you need to make a searchable phone directory of your organization available on the Internet. ... This isn’t a difficult task, but it has security repercussions. If you’ve already deployed AD DS and you have the employees’ phone numbers available in that directory, it might not be a good idea to expose your AD DS environment to the Internet for security reasons. Using AD LDS is a great alternative because it can be deployed separately from AD DS and it’s designed to simply provide the information retrieval service that you need without the complications involved with Kerberos authentication and group policies."
