This approach assumes a dynamic and negotiated reality unlike the quantitative approach, which assumes a fixed and measurable reality. In the approach, data are collected through participant’s observation and interviews. The data then are analyses by themes from descriptions by the analyst and then are repeated in the language of the analyst. 3.3 Population and Sampling The group targeted by this sampling are the hospital doctors and nurses who’ll provide need information of how the current system works and the constraints. 3.3.1 Sampling Techniques 3.3.1 Random Sampling Random sampling refers to the sampling technique in which each and every item of the population is given an equal opportunity of being included in the sample. This sampling technique was applied to collect information from the doctors who were picked randomly using the lottery method with a sample size of 3. 3.2.2 Purposive Sampling Purposive sampling is a form of non-probability sampling in which researchers rely on their own judgement when choosing members of the population to participate in a survey. This sampling technique was used to collect data from the nurses as they would provide the most needed information about the current system as they interact more with it. The analyst selected nurses based on characteristics as expertise and professional opinions that concern siakago Hospital. The analyst then made his own judgment choosing who ask to participate. This method helped the analyst to understand to know the problem of furniture in the area and the amicable solution to counter the problems in the area. 3.2.3 Systematic Sampling Systematic sampling is type of probability sampling method in which members from a larger population are selected according to a fixed periodic interval. The sampling technique was used to collect data from the patients who visits the hospital for treatment or consultation. The analyst selected patients at regular intervals from sampling frame. The analyst chose a sample size of 25 from a population of 50, select every 50/25=2nd members of the sampling frame. Systematic sampling is often more convenient than simple random sampling, and it is easy to administer. 3.4 Data Collection Methods Various data collection methods were used to ensure that accurate and reliable data was collected to help in developing the proposed system and understanding the require
