Explanation of the survey scale
| Impact | Description | Example | |
|---|---|---|---|
| 1 | Less occurrence | The factor is unlikely to cause rework. Any impact on the project is negligible, and it rarely results in the need for corrections or adjustments | A minor, easily correctable discrepancy in a non-critical area of the project |
| 2 | Moderate occurrence | The factor occasionally causes rework, but its effects are limited. It results in minor adjustments that do not significantly affect the overall project timeline or budget | Small errors in specifications that require minor changes to materials or processes |
| 3 | High occurrence | The factor frequently causes rework, leading to noticeable disruptions. It results in moderate adjustments that can affect the project timeline or budget to a certain extent | Incomplete drawings that necessitate multiple corrections and affect the sequencing of certain tasks |
| 4 | Very high occurrence | The factor consistently causes significant rework, leading to major disruptions. It results in substantial adjustments that heavily impact the project timeline, budget, and overall quality | Major design flaws or inadequate funding leading to significant delays, cost overruns, and extensive rework |
