This research aims to create a set of critical success factors among project phases based on a key performance index that may be used to evaluate the success of construction projects in the Iraqi construction industry to meet the time, cost, quality, safety and health limits. Two approaches are used in the methodology. First, a literature review with an intensive interview with construction experiments was conducted to identify 38 success factors for high-performance initiatives and four KPI (cost, time, quality, safety and health). Then, a questionnaire was used to perform the empirical study. A survey was administered to 120 practitioners in the Iraqi construction sector. SPSS Data was analysed using version-24, which used descriptive statistics, Cronbach’s Alpha, mean score, one way ANOVA, eventually, the t-test to determine the most critical success factors. The paper offers a basic framework criterion for 30 critical successful factors depend on key performance index as the indicators throughout the pre-construction, construction and post construction, and an increased successful rate among project phases by achieved concentrating on these important aspects. This research study involved only governement buildings projects completed. The researcher did not address in his study the suspended projects because projects are not completed for different reasons such as economic crises and the ISIS war. Iraqi construction professionals make up the study's not all Iraqi region but representative sample. As a result of the sophisticated nature of building projects, researchers investigate, create, and develop building participants' performance that would help construction companies alleviate the situation and resolve the complexity connected with construction projects to deliver a successful performance. KPI by these successes factors through the project phases guide construction organisations' strategic decision-making when developing future effective construction industry strategies; an in-depth look at the current construction market environment in Iraq, which is an accurate representation of developing nations as a whole, is provided by this study's results.
