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 approach. Qualitative Approach 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). Quantitative Approach 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 questions. 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 Requires control Focuses on Form of Research Strategy over behavioural Contemporary Question event? events?

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. 4.3.2 Survey 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. 4.3.3 History 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...
