5.6.2.1 Variance Analysis
Variance analysis is a technique for determining the cause and degree of difference between the baseline and actual performance. Project performance measurements are used to assess the magnitude of variation from the original scope baseline. Important aspects of project scope control include determining the cause and degree of variance relative to the scope baseline (Section 5.4.3.1) and deciding whether corrective or preventive action is required.

6.1.1.3 Enterprise Environmental Factors
Described in Section 2.1.5. The enterprise environmental factors that influence the Plan Schedule Management process include, but are not limited to:
Organizational culture and structure can all influence schedule management;

Resource availability and skills that may influence schedule planning;

Project management software provides the scheduling tool and alternative possibilities for managing the

schedule;
Published commercial information, such as resource productivity information, is often available from

commercial databases; and
Organizational work authorization systems.

11.4.2.2 Quantitative Risk Analysis and Modeling Techniques page 337
Commonly used techniques use both event-oriented and project-oriented analysis approaches, including:
* Sensitivity analysis. Sensitivity analysis helps to determine which risks have the most potential impact on the project. It helps to understand how the variations in project's objectives correlate with variations in different uncertainties. Conversely, it examines the extent to which the uncertainty of each project element affects the objective being studied when all other uncertain elements are held at their baseline values. One typical display of sensitivity analysis is the tornado diagram (Figure 11-15), which is useful for comparing relative importance and impact of variables that have a high degree of uncertainty to those that are more stable.
The Tornado diagram is also helpful in analyzing risk-taking scenarios enabled on specific risks whose quantitative analysis highlights possible benefits greater than corresponding identified negative impacts. A tornado diagram is a special type of bar chart used in sensitivity analysis for comparing the relative importance of the variables. In a tornado diagram, the Y-axis contains each type of uncertainty at base values, and the X- axis contains the spread or correlation of the uncertainty to the studied output. In this figure, each uncertainty contains a horizontal bar and is ordered vertically to show uncertainties with a decreasing spread from the base values.
