Summarised techniques used at different risk management process
| Context of Risk | Risk identification | Risk analysis | Risk evaluation | Risk mitigation |
|---|---|---|---|---|
| Project network diagrams. E.g. critical path method and programme evaluation and review technique (majority) | Checklist: It is a traditional way to investigate symptoms of possible risk scenarios (majority) (Oke et al., 2023) | Probability and impact grids: It reveals the significance of risk events (majority) | Decision tree analysis: The decision process and output are structured via a decision process (majority) | A reactive approach: It is a risk mitigation approach after risk events (majority) |
| Precedence diagramming method: It is an advanced form of project network diagramming that can show the relationship and overlapping of construction activities (majority) | Influence diagrams: It is a graphical representation of the structure and present uncertain events, consequences, if any, and their relationships graphically (P23 and P26) | Estimating system reliability: It is tool for exploring system elements (P2 and P18) | Portfolio management: It compares multiple construction projects regarding the risk associated with investment (P26) | Pro-active approach: An action conducted based on the probability of a risk event (majority) |
| Generalised Activity Networks (GAN): This is a graphical presentation of the possible tasks (P5, P12, and P23) | Cause-and-effect diagrams: It is also known as fishbone diagram and graphically represent the root causes-and-effect of issues (majority) | Fault tree analysis: It is used to establish the chance of a failure task occurring in the task (P13 and P22) | Multiple criteria decision-making method: The positive and negative variables are considered a decision-making criterion (majority) | |
| Design Structure Matrix (DSM): It shows the precedence relationship of construction activities (P5, P13, P22, and P28) | Fault tree: It is a visual technique used to break down failure in the system and show the cause-and-effect relationship (P22) | Event tree analysis: It determines how the event is likely to occur from the previous event (P22 and P25) | ||
| IDEF0 Functional Modelling: This is a graphical representation of construction activities with arrows to show the flow (inputs, outputs, and controls) (P18 and P22) | Event tree: An advanced form of fault tree that reveals the potential consequences and assign to tasks (P3, P17, and P27) | Sensitivity analysis and simulation: It reflects on responses by the system as changes occur (majority) |
