Unformatted text preview: research, we are primarily Descriptive, since our research is intended to obtain
information pertaining to the current status of the WAP services. We will make a
systematic attempt to workout any flaws in WAP services. Since, we do not have
intention to investigate cause/effect relation therefore our research is descriptive. 4.2 Research Approach
The choice of research approach is not merely dependent on researcher’s
epistemological position and pre knowledge, but should also be influenced by the
research questions he/she set out to highlight (Yin, 1994). There are two choices of
research approaches are available, and these are qualitative approach and quantitative
A qualitative research approach provides a deeper understanding of the phenomenon
under investigation. Furthermore, qualitative data are characterised by the richness and
fullness based on the opportunity to explore a subject. The nature of qualitative data has
implications for both its collection and its analysis. The aim of a qualitative study is
primarily to understand, not to explain (Denscombe, 2003).
A quantitative research measures and analyzes casual relationships between variables,
not the processes Denscombe (2003). He further states that quantitative research
methods are used within natural science, the meanings are often derived from numbers
and the aim is usually explanatory, to permit generalizations and to enable predictions
about the future. 45 Denscombe (2003) differentiate between qualitative and quantitative research by
describing their distinctive features. More specifically he justify that qualitative research
implies an emphasis on processes and meanings that are not measured in terms of
quantity amount, intensity or frequency.
As the aim of our study is to evaluate the usability principles of WAP enabled services
from user’s point of view and to workout any flaws in existing WAP services, therefore
while taking our research problem and research questions into consideration, we find it
suitable to use the qualitative research approach because the aim of a qualitative study
is primarily to understand, not to explain (Denscombe, 2003). 4.3 Research Strategy
In this section with the view to do qualitative research as a general research approach,
the focus now turns to the research strategies available to collect the data. Yin (1994)
states five primary research strategies in the social sciences. These include experiments,
surveys, archival analysis, histories and case studies. According to Yin (1994) the
selection of these strategies depends upon three distinct conditions:
1. The type of research question posed: This study asks primarily how and why research
2. The extent of control an investigator has over actual behavioural events: This
researcher has none; his job is to observe and interview.
3. The degree of focus on contemporary as opposed to behaviour events: This study
focuses on the how and why of a contemporary event.
These different conditions and their relevant situation can be found in table 4.3.1

46 4.3.1 Experiments According to Yin (1994) the experimental method involves manipulating one variable
to determine if changes in one variable cause changes in another variable. The
experiments rely on controlled methods, random assignment, and the manipulation of
variable test as hypothesis. This strategy is used when the researcher need to compare
two variables and examine their cause and effect relationships, however, in our case the
experiment is not suitable strategy because of the lack of control over behavioral events.
According to Zikmund (1994) survey is a research technique in which information is
collected by interviews with a large number of respondents using a pre-designed
questionnaire. In our study, this method is unsuitable because our intention is to
evaluate the usability principles of WAP enabled services where, particular user
experience or knowledge is required.
According to Yin (1994) history method deals with past, and is used when no relevant
persons are alive to interview or report. This method is specifically used to describe the
content, structure and function of the data which collected for research
4.3.4 Archival Information
According to Zikmund (1994) the purpose of this technique is to describe or prevalence
of a phenomenon. In our research, archival records are not appropriate since the study
does not answer to question how much.
4.3.5 Case Study
According to Denscombe (2003) case studies represent investigations in which the
interest is focused on detailed, in-depth descriptions and analysis of individual cases. In
addition, case studies offer an important advantage, since one can gain a holistic view of
a process, as detail...
