4. Critical Appraisal of the Articles All selected articles, authors’ (Kapur 2016; Kikwasi 2012; Ramachandra & Rotimi 2015; Wong & Vimonsatit 2012) emphasis the importance and the contribution to the economy of construction industry in Australia. At the same time, they (Kapur 2016; Kikwasi 2012; Ramachandra &Rotimi 2015; Wong & Vimonsatit 2012) highlight that more than 50% of projects cannot complete on time and cost overruns due to financial problems and poor project management, thus all four articles (Kapur 2016; Kikwasi 2012; Ramachandra & Rotimi 2015; Wong & Vimonsatit 2012) have analyzed over financial problems and the stakeholders non-excusable activities to explore the factors to reduce project delays, cost overruns and payment issues in projects. The article (Kikwasi 2012) describes causes of delayed payment as a one of the factors, which lead to project, delays and as disruptions arouse in a project. However, other three articles (Kapur 2016; Ramachandra & Rotimi 2015; Wong & Vimonsatit 2012) analyze delayed payment factors as financial problems, which are faced by the project team. The article (Kikwasi 2012), (Ramachandra & Rotimi 2015) and (Wong & Vimonsatit 2012) have selected primary data to research on their topics while the article (Kapur 2016) use secondary data for the analysis. However, only article (Ramachandra & Rotimi 2015) selects many primary data methods, preliminary interview, questionnaires and structured interview to prove the factors more accurately while other two use only questionnaire-based surveys. The article (Kikwasi 2012), (Ramachandra & Rotimi 2015) and (Wong & Vimonsatit 2012) try to investigate all stakeholders’ engagement of the non – excusable activities of clients, contractors, consultants and bankers that affect to payment delays. In contrast, the article (Kapur 2016) concern only about clients, contractors and consultants involvement that may affect the accuracy of the analysis. However, only article (Wong & Vimonsatit 2012) compares the results with developing countries, which help to explore further understanding and directing to a better path. Poor financial or cash flow management, changes made by clients and communication errors are the most trended causes for delayed payment, which have identified by authors (Kapur 2016; Kikwasi 2012; Ramachandra & Rotimi 2015; Wong & Vimonsatit 2012) in all four articles.
