CHAPTER 3RESEARCH METHODOLOGY3.
1 IntroductionMethodologyis defined as more than just a methods being used to collect data. It is a wayto find out the result of a given problem or research. Apart from that, it is also a way ofsearching or solving the research problem. Research methodology is important asthe guidance in completing the research study.
In this study, six steps of research methodology being used, which are problem statement and objective identification, literature review, collecting data, data analysis and discussion, conclusions andpresentation. A systematic procedure isvery significant in collecting, analyzing and documenting data to get a goodresult. 3.2 Methodology FlowchartProblem Statementand ObjectivesLiterature ReviewCollectingDataQuestionnairesInterviewData Analysis andResults DiscussionConclusion andRecommendationsPresentationand Feedback from PanelsFigure3.1: Flow Chart of Methodology 3.
3.1 Problem Statementand ObjectivesAproblem statement is an understandable explanation of the issue that needs tobe addressed by researchers. It is used to maintain focus of the researcherfrom the beginning of the process, to keep the researcher stay on track until the study is completed to final stagewhich is presentation. It also can be used to check whether the researchoutcome did solve the problem statement. Next,objectives of the study are identified from the problemstatement.
Objectives are the matters that need to be achieved by the study. The objectives include obtaining answers to the research question or hypothesis. 3.2.2 Literature ReviewFromthe flowchart, literature review is theprocess of gathering the information from other source and documenting it. Literature review is an evaluation of previous research and it can bethe entire paper in itself. In theother word, it is a synopsis of the whole research study that going to becarried out.
Journals, website and books are the several types of sources being used to complete the literature review on Identification ofCritical Success Factors of industry 4.0 Among Construction company.3.2.3 Collecting DataTheprocess of collecting data involving two method which are questionnaire andliterature study.
50 contractors with grade G7 around Shah Alam, Selangor area will be distributed with questionnaire through email or by hand. The questionnaire will focused on industry 4.0 activities andhow much the level of a company did practiced industry 4.0 during theircompletion of construction project. The questionnaire survey will be conducted and it was produced related to the objectives of the study. The questionnairewill be contributed to population of 50 grade G7 contractors in Shah Alam, Selangor.
The purpose of thismethod is to collect the feedback from the respondents, and the data collectedwill be analyzed and documented. 3.2.3.
1 Data Collection MethodDatacollection is to collect any information which related to the study in order toproduce the result of the study. The data collection method is choose based onseveral factors such as the basis andrange of study, level of precision required and time factor. In this study, the data collection methodbeing used is primary research and secondary research. 3.
2.3.2 Primary DataGenerally, primary data is the data collected from the actual sources in order to complete the research. Primarydata involving collection data through observation and questionnairesurveys. In short, the data will be obtained by using questionnaire survey. The questionnaire survey will be distributed to the targeted respondents which includes the construction community. The questionnaire will be distributed through mail, fax, telephone or by personal approach.
The data collected are original in character forthe result obtain is fresh from the respondents before being evaluated. Next,the data will be analyzed and documented to make sure it is easy beingevaluated. Thequestionnaire is having three sections which are Section A, Section B, SectionC and Section D. The background and personal information of the company will beincluded in Section A. There are several variables will be ask in Section A,for example:i. The grade of the contractor.
ii. Designation of the respondent.iii. Years of experience of the respondent inconstruction industry.iv. Number of project being involved by theorganization.Section B will be focused on the level of awareness and understanding on Industry 4.0.
The design of questionnairesurvey must be relevant to the objectives of the study. In this section, the respondent need to markon the scale between one (1) and five(5) in order to simplify the respondent. According to Ordinal Scale of Agreement, num ber one (1) represent strongly disagree, number two (2) represent disagree, number three (3) represent neutral, number four (4)represent agree and number five (5) represent strongly agree. The example ofthe ordinal scale is shown Figure220.127.116.11 below.Figure 3.
2.3.2Likert’s ScaleOrdinal in ascending order 1 2 3 4 5 Section C will be focusing on the factors affecting the implementation of Industry 4.0 while section D related to the challenges of the implementation of Industry 4.0 amongconstruction company. Both section willbe using the same scale as Section B, but in Section D, the respondents will begiven opportunity to deliver their suggestion and comments. 3.2.
3.3 Sample size ofpopulationThearea selected for the study area is Shah Alam, Selangor while the targetedrespondent is grade G7 contractors which had registered with CIDB. The totalnumber of G7 contractors in Shah Alam is 807 (CIDB, 2016). Thus, by usingRobert et al.
, (1970) formula, the sample size of population is calculated. Theformula is as follows:S = X2NP(1-P) ÷ D2(N-1) +X2P(1-P)S= Required sample sizeX2= Table value of chi-square for 1 degree of freedom at the desiredconfidence level(3.841)N= Population sizeP= Population proportion (assume to be 0.50 since this would provide the maximumsample size)D2= Degree of accuracy expressed as proportion (0.05)Thetotal number of grade G7 contractors in Shah Alam is 777. Thus, the sample size of population is calculated using Robert et al,(1970) formula.Samplesize = 3.
841 × 777 × 0.5 × (1-0.5) ÷ 0.
05 × (777-1) + 3.841 × 0.5 ×(1-0.5) = 40 3.2.
3.4 Secondary DataSecondary data defines as data collected from published materials such as journals, books being used by previousresearcher, thesis, articles, or websites. Secondary data is efficient becauseit can be compared to the original findings from the study area, Shah Alam,Selangor. There are several advantages of using secondary data which are:i.
It offers a lot of general background of thestudy.ii. It save time and cost.iii. Information from previous researchers can becompared and analyzed.
iv. It gives information on the literature reviewas well.3.2.4 Data Analysis and Result DiscussionData analysis is the stage after all the information had being collected. The data will be analyzed and documented in the proper way for easy evaluated by thepanels.
Next, the expected result will be identified basedon the data analysis and the result is discussed on why and how the result is obtained. It is better to have a conclusion in the end of the report with some recommendation related to the topic for any improvement needed inthe future
