In today’s competitive market, survival and response to customer needs and
expectations are enabled through high-quality products for low costs – quality
products provided by suppliers fulfilling today’s quality-requirements for a low
price. Companies have until recent years selected suppliers only according to a
pricing structure, leaving other criteria’s, such as quality, behind.
The purpose of this master thesis is therefore to investigate quality aspects that
must be considered from a supplier evaluation perspective and design a simple
evaluation tool for first-time supplier selections. Both new and existing
suppliers will be tested with the tool according to information given during a
case study made at Flexit AS, a Norwegian ventilation-systems company
looking to introduce a structured approach for selecting suppliers.
Through an extensive literature- and empirical study, where a survey, of which
evaluation criteria’s to be included in the evaluation tool, was conducted
together with several both semi-structured and unstructured interviews, a
foundation for the design of the tool was presented.
Quality management systems and quality performance measurements, such as
rejection rate and delivery precision, are considered as fundamental aspects to
consider when assessing a supplier. Acceptance levels of approval are set
according to in-house objectives. If any evaluation tool including quality
should be usable, an in-house quality system must therefore first be
implemented by the in-house company – a notable improvement
recommended to the case company.
The design of the tool given from the thesis provides the evaluator with an
opportunity to visualize and compare existing suppliers according to five
criteria’s including cost, together with an additional spreadsheet for evaluation
of new suppliers put forward as a foundation and an indicator if new suppliers
are considering quality on a basic level.
