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]

"Business process improvement (BPI) is a systematic approach to help an organization optimize its underlying processes to achieve more efficient results. ...
An organization is only as good as its processes. To be able to make the necessary changes in an organization, one needs to understand the key processes of the company. Rummler and Brache suggested a model for running a Process Improvement and Management project (PI&M), containing the following steps:
1. Identify the process to be improved (based on a critical business issue): The identification of key processes can be a formal or informal exercise. The management team might select processes by applying a set of criteria derived from strategic and tactical priorities, or process selection is based on obvious performance gaps. It is important is to select the process(es) which have the greatest impact on a competitive advantage or customer requirement.
2. Develop the objective(s) for the project based on the requirements of the process: The focus might be on quality improvement, productivity, cost, customer service or cycle time. The goal is however always the same; to get the key process under control.
3. Select the members of the cross-functional team: A horizontal (cross-functional) analysis is carried out by a team composed of representatives of all functions involved in the process. While a consultant or in-house staff person can do the job, the quality of the analysis and the commitment to change is far greater with a cross-functional team.
4. Document the current process by creating a flowchart or "organization map": Describe the process regarding the Organizational level, the Process level and the Job/ Performer level according to Rummler. Develop a cross-functional process map for the process.
5. Identify "disconnects" in the process: “Disconnections” are everything that inhibit the efficiency and effectiveness of the process. The identification should be categorized into the three levels: The Organizational level, the Process level and the Job/ Performer level.
6. Recommend changes (organizational, in the process or in its execution): Categorize and prioritize the main problems and possibilities, evaluate alternative solutions. Develop a cross-functional process map for the recommended process.
7. Establish process and sub-process measures: The process measures should reflect the objectives of the project.
8. Implement the improvements." [Business process improvement. Wikipedia]
