No / The importance of a collaborative approach between the project team, end-users, and stakeholders in managing complex decisions and risks in project environments has long been emphasized. The Porter model emphasizes the need to focus on client needs and competitive advantage. However, a lack of resources and capability development may hinder the project team's ability to provide appropriate services. Supervisors, team members, and end-users can play a supportive role in easing complexity in risk management and decision-making. It is important to understand standards as performance measures for decision-making and the need for detailed knowledge of the project brief. The value of group decision support systems and low-intensity involvements in decision-making would give rise to involving end-users in critical decision-making, the importance of focusing on organizational culture and strategic planning, and the need for a change of mindset to align individual perceptions with the norm. It is also important to gather and analyze information before making a decision. While some project teams see end-users as a threat to their judgment, the research emphasizes the duty to respond to end-users' needs and highlights the value they add to risk assessment.
