Identifing key Factors Affecting Project Portfolio Management Effectiveness Aimed at Reducing Environmental Hazards in Iranian construction Projects

The construction industry has an enormous impact on the environment, and the processes involved in construction projects are one of the most important factors affecting the environment. The present study examines key indicators in the effectiveness of project portfolio management as a strategy to reduce environmental hazards in construction industry projects. Project portfolio management (PPM) is used in many organizations as an approach to coordinate a portfolio of projects or programs to achieve specific organization goals. A common goal of PPM is to ensure that an organization is doing the right thing, rather than just doing things right. The effectiveness of project portfolio management in organizations has an important role that if it would neglect can lead to widespread environmental hazards. Several factors are effective in the effectiveness of project portfolio management. This research focuses on identifying the most important of these factors. The research approach is qualitative-quantitative (mixed) and uses a descriptive research approach. The statistical population used is construction companies that use the concept of project portfolio management in their organization and the data were collected through interviews and questionnaires. Experts identified the key indicators of project portfolio management success and effectiveness in seven groups and then, using a questionnaire and quantitative analysis, identified three groups of strategic, operational and organizational structure among the most important indicators. Based on the findings, organizations can improve their context in order to make more effective use of project portfolio management, with the aim of reducing biological hazards during the implementation of construction projects.
