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.

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 Figure3.2.3.2 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
