Transcribed Image Text: benefits, Sam decided to undertake focus group meetings with each of the four groups in each
of the three supply chains (twelve meetings in total), to obtain data about the attributes used to
measure service quality. After the meetings, Sam used content analysis to generate a number
of measures of service quality. On comparing the measures she had extracted from the
data with existing service quality constructs she was able to categorise them under headings
similar to those used in SERVQUAL: Reliability, Assurance, Tangibles, Empathy and
Responsiveness.
Her next two research objectives required:
1 data to be collected on perceptions of service quality;
1 a comparison of measures of service quality and perceptions;
1 analysis of the factors that influenced differences between measures and perceptions.
In addition, Sam recognised that the measures she had generated through her focus groups
needed further validation by a larger sample of people in each of the supply chains. Sam's
initial thought was to carry out interviews to obtain a larger amount of data that would address
the objectives and the issue of validity; however, she soon realised that this would be very
costly and time consuming in practice, and would not necessarily give her the data in a form
suitable for analysis. She therefore decided an appropriate approach for the remainder of the
research would be to survey opinions and attitudes of people within the three supply chains
using a questionnaire.
To ensure the data gained from her questionnaire would be suitable for analysis, Sam utilised
the Service Template process used in previous research (Williams et al., 1999). This allows the
identification and measurement of different dimensions and perceptions of service quality, and
so fitted well with Sam's research objectives. In line with the Service Template process, Sam
developed her questionnaire by first listing each measure of service quality
identified through her focus groups as an item in the questionnaire. The importance of the item
would be measured as an expectation, and the current performance against the item would be
recorded as a perception. This would be recorded using a 10-point Likert scale, anchored by
ideal and worst situation descriptors which Sam could derive from her focus group meetings.
This is illustrated in the following extract from Sam's questionnaire:
For the Medical Equipment supply chain, please rate the following items on the scale below,
with 10 representing the ideal situation and 1 the worst. For each item, use E to indicate your
expected level of service, and P for your perception of actual performance.

In addition, she included a number of demographic questions relating to the respondent's
position in the supply chain, role, age, sex and length of time in organisation. These she placed
at the end of her questionnaire. Including these questions would allow her to analyse patterns
Transcribed Image Text: During her degree placement Sam Jones spent a year working in the Purchasing Services
department of a local acute hospital National Health Service (NHS) Trust. During her time in
the organisation she saw at first hand the pressures faced by the organisation as it strove to
deliver the vision of The NHS Plan (Department of Health, 2000) of a health service that
provided timely, high-quality, value-for-money and patient-centred care. Specifically, she
witnessed the changes being introduced in relation to supply chain policy and practice as the
Purchasing Services department responded to the challenge of delivering quality products and
services that met the needs of the end patient and other service users. Embarking on her
research project Sam decided to focus on the topic of measuring service quality in health care
supply chains. During the placement the Head of Purchasing Services had expressed an inter-
est in the topic as being both important and timely and had offered to assist in facilitating the
collecting of data. In addition, an initial review of the literature suggested that there was scope
to make a worthwhile contribution to knowledge by researching the topic.
Having completed a review of the literature on supply chain management and service quality,
Sam established an overarching aim of her research project, which was to measure and com-
pare perceptions of service quality in health care supply chains. Through her reading of the
literacture and having undertaken some initial exploratory intervies with Purchasing Services
staff she had developed the following objectives for the research:
i to establish how service quality is measured in health care supply chains;
1 to investigate the factors that influence perceptions of service quality of different
people/groups within health care supply chain chains;
i to establish how performance is reflected in the degree of alignment between measures and
perceptions.
A major issue facing Sam was deciding upon a unit of analysis. To do this she needed to
understand how the supply chains worked. It soon became obvious that NHS supply chains are
complex, spanning geographical locations and sectors, such as acute hospitals, primary care
organisations and health authorities; and encompassing diverse products and services, such as
personnel, drugs and pharmaceuticals, medical equipment, information technology, transport
and car parking. In order to be able to compare and contrast measures and perceptions she
decided that she needed to select different types of services. Therefore she chose to investigate
three services managed by the NHS Trust in which she had worked during her placement:
personnel, transport and medical equipment. For each service she identified a supply chain
comprising of four groups: Primary Care Trust (patients and general practitioners), Strategic
Health Authority, the acute hospital NHS Trust, and a supplier to the hospital.
To meet the research's first objective of establishing how service quality is measured Sam
considered undertaking a survey using a previously validated instrument, such as SERVQUAL
(Parasuraman et al., 1985). This presented Sam with a dilemma. Whilst there were clear
benefits in terms of establishing external validity, with such instruments having been shown
through prior research to contain measures of service quality that are appropriate to a wide
range of situations, other literature suggested that such generic instruments may not provide
sufficient detail of the measures important in the health care context (for example: Robinson,
1999). Judging that the limitations of using a previously validated instrument outweighed the
