4.11.4 Reliability
Reliability is the extent to which a measure can produce consistent results
(Yin, 2003; Creswell & Plano, 2011). The reliability criteria would therefore
relate to the collection, compilation, processing of the information and
deriving of conclusions from the final analysis. The researcher used the case
study protocol to ensure that the data and information collected for this
study, whether secondary or primary, were clearly documented. And the
protocol also enhanced the development of case study data base during the
data collection phase. Such use of protocol and development of case
database can improve the study‘s reliability (Yin, 2003). Accordingly, the
methods can be carefully applied and may still result in similar findings
since the aforementioned reliability enhancement criteria for case study
were clearly applied in the study.
