Words on this page that have been underlined and italicized can be found in the glossary on the right-hand side of the page.

Tip

To view any result chart next to risk or ranging inputs, open the same file in another instance of NetRisk and snap them each side-by-side.

Distribution Charts

Distribution charts show bars representing the number of iterations or cost observed during simulation, as well the cumulative total via the cumulative curve. Distribution charts can be viewed for start date, finish date, duration, drift, float, total float, cost, and probabilistic cash flow. As different activities or WBS nodes are selected in the Table pane, the chart will update accordingly. 

  1. Click the Results  driver.

  2. Click the Simulation dropdown in the Table pane and choose a desired simulation.

  3. Click the Chart Type dropdown in the Chart pane and choose the desired chart.

Tip

Hover over any bar or any data point to see the actual values.

In the Table pane, activities and their data correspond to the state when the simulation was ran, regardless of whether or not the model has since been updated.

Adding/Removing Markers

Markers perform the following functions:

FunctionChart(s)
Call attention to specific values on the chartCompletion Date, Start Date, Duration, Drift, Float, Total Float, Cost, Cash Flow
Add or remove series of data for desired percentilesCash Flow

Four types of markers exists, as follows:

Marker TypeDefinitionInputs
Delta Marker

Shows the variance between two values, for example, the deterministic duration and the P80 duration. Not available for Cash Flow.


The horizontal portion of the delta marker will be drawn at whatever height is entered in the Percentile column.

  • Value 1: the low
  • Value 2: the high
  • Color: the line color
  • Percentile: the height at which to draw the delta label
  • Line: whether or not to show the vertical lines
Deterministic Marker

Shows the planned (pre-simulation) value or data.


For the Cost chart, if an activity was in-progress and had both a Planned Cost and Actual Cost entered on the Ranging tab, two deterministic markers will show up on the chart: one for "Planned Cost" and one for "Projected Cost". Projected cost is equal to the planned cost minus the actual cost for the remaining duration.

  • Color: the line color (not applicable for Cash Flow)
  • Line: whether or not to show the vertical lines (not applicable for Cash Flow)
P Value MarkerA P value is the value which was observed during at least X% of iterations. For example, the P80 Finish Date is the finish date observed during at least 80% of the iterations. To put it another way, 80% of the iterations completed on that date or earlier. The P80 cash flow is the cash flow observed during at least 80% of the iterations.
  • Color: the line color (not applicable for Cash Flow)
  • Percentile: the desired percentile
  • Line: whether or not to show the vertical lines (not applicable for Cash Flow)
Variance Marker

Shows the variance between two points at the selected percentile.


Only available when comparing more than one series (e.g. simulation, activity, or cash flow percentile)

  • Value 1: the EARLIER data
  • Value 2: the LATER data
  • Color: the line color
  • Percentile: the p value for comparison (not applicable for Cash Flow)
  • Line: whether or not to show the vertical lines
  • Cash Flow: an option for choosing between cumulative variance (bars) or non-cumulative variance (curves) (only available for Cash Flow)
  • Date: the date for comparison (only applicable for Cash Flow)


Variance markers are saved on a series-by-series basis. For example, if you are doing a comparison and click to another activity or WBS row in the Table pane (or change simulations or chart type), the variance will disappear from the chart. If you change back, it will reappear. Therefore, it is recommended to add a new variance marker for each the new activity or WBS row that you want to save.

  1. Click the Results  driver.

  2. In the Chart Properties pane, click the Add button next to the Markers list.

  3. Click the dropdown in the Type column to change marker types.

  4. To remove, select the row in the list and click Remove.

Recalculating the X-Intervals for Cost Charts

The x-axis of the cost distribution chart can be grouped into smaller or larger buckets, e.g. $100, $1,000, $10,000 etc. Larger intervals will reduce the number of bars and smaller intervals will increase the number of bars. For example, with an interval of $1,000, an iteration with a total cost of $500 and an iteration with a total cost of $1,000 would be represented by a single bar with 2 hits rather than than two separate bars each with one hit.

The cash flow chart can be recalculated based on days, weeks, months (default), quarters, or years. When choosing weeks, whichever day the project starts on will define the beginning of the week. To recalculate the x-axis interval:

  1. Click the Results  driver.

  2. In the Chart pane, click the dropdown next to Chart Type and choose either Cost or Cash Flow.

  3. In the toolbar above the chart, click the dropdown next to X-Axis Interval and choose as desired.

Scatter Plots

Distribution charts show a single variable (completion, OR cost, OR duration). The problem is, if we target a date with an 80% probability of being met, there are many costs associated with that date, some of which are not 80% likely to occur. Similarly, if we target a cost with an 80% probability of being met, there are many dates associated with that cost, some of which are not 80% likely to occur. Targeting the P80 cost and P80 finish will not result in an overall P80. Scatter plots combine two variables and allow us to see the joint probabilities. Scatter plots are available for Completion & Cost or Duration & Cost.

Scatter plots are divided into four quadrants, which can be adjusted by moving the vertical and horizontal lines. Each quadrant shows the percentage of iterations that fall within the quadrant. To see, for example, the joint P80, move each line until the quadrant at the bottom left (Q3) shows 80%. You'll see there are many combinations of cost and date to achieve this. A curve can be drawn connecting all of the combinations called the joint confidence level curve by clicking the Joint Confidence Colors icon in the chart toolbar. The curves default, and are fixed, to 20%, 50%, and 80%. 

  1. Click the Results  driver.

  2. In the Chart pane, click the dropdown next to Chart Type and choose either Completion & Cost or Duration & Cost.

  3. Click on either line or at the center and adjust until you see the desired probability or value for each line.

  4. To change color scheme, click the Joint Confidence Colors  icon in the chart toolbar.

Overlaying Scatter Plot and Cash Flow 

While viewing the cash flow chart, the scatter plot can be overlayed on top of it. To do so:

  1. Click the Results  driver.

  2. In the Chart pane, click the dropdown next to Chart Type and choose Cash Flow.

  3. In the toolbar above the chart, click the Scatter button.

Tornado Charts

Tornado charts show results organized from high to low for a variety of data sets.

Tip

When the number of results is larger than the amount of vertical space, bars will be merged to make them fit on a single screen. To view every bar individually, use the scroll wheel on your mouse to "zoom in". The chart can then be scrolled up and down.

ChartDefinition
Activity Priority The significance of an activity on the project's duration defined as criticality * (1+cruciality). Milestones, WBS summaries, hammocks, or LOE's will not show up.
CriticalityThe proportion of iterations activities were observed on the path with 0 days of float (GPM) or total float (CPM).
Duration Cruciality The correlation between activity durations and the duration of the project. Milestones, WBS summaries, hammocks, or LOE's will not show up.
Risk Priority

The potential gain in calendar days or dollars after removing each risk during simulation.


Non-working calendars are NOT treated as risks/removed when calculating risk priority.

Risk Sensitivity

The correlation between existence of a risk and the duration or cost of the project. A positive result suggests that when the risk occurs, the project takes or cost more; a negative result suggests that when the risk occurs, the project takes or costs less:

ResultMeaning

0 - 0.2

The correlation is very weak, or essentially random. 
0.2 - 0.6There is some correlation
0.6 - 1The correlation is strong

As different activities or WBS nodes are selected in the Table pane, the chart will update accordingly, as well as be filtered or recalculated as indicated. To view tornado charts:

  1. Click the Results  driver.

  2. Click the Simulation dropdown in the Table pane and choose a desired simulation.

  3. Click the Chart Type dropdown in the Chart pane and choose accordingly.

Tip

To do so:

  1. Click the Results  driver.

  2. Select the desired element directly on the chart with the mouse. The selected element will be confirmed in the toolbar above the chart, e.g. "Title Formatting".

  3. Click the desired icon or font picker immediately to the right.

Comparing Charts

The following comparisons can be made:

  • Simulation to simulation, for example completion dates for the same activity in multiple simulations
  • Activity to activity, for example completion dates for multiple activities within the same simulation
  • Multiples, for example completion dates for multiple activities in multiple simulations

Charts of different types cannot be compared to one another. When comparing tornado charts for multiple simulations, the order of the simulation selected will determine the order for the tornado.

To compare Risk Priority for two simulations, select the first simulation group (to determine the tornado order) and then select each run individually beneath the second simulation group. If you select the second group parent, the first simulation group will be deselected.

Simulation to Simulation

  1. Click the Results  driver.

  2. Click the Simulation dropdown above the Table pane.

  3. Check the box next to each simulation desired.

  4. Click Close.

The table will only show activities and their data for the LAST simulation clicked, indicated above the list. If an activity existed in the last simulation clicked but did NOT exist in one of the other simulations, a series will NOT show up for it on the chart. If an activity didn't exist in the last simulation clicked, it will not show up in the table at all.

Variance markers are saved on a series-by-series basis. For example, if you are doing a comparison and click to another activity or WBS row in the Table pane (or change simulations or chart type), the variance will disappear from the chart. If you change back, it will reappear. Therefore, it is recommended to add a new variance marker for each the new activity or WBS row that you want to save.

At this time, colors are not saved during comparisons, but are randomized. For example, if you are doing a comparison and click to another activity or WBS row in the Table pane (or change simulations or chart type), the colors will change. For now, there is no way around this and it is expected.


Activity to Activity

  1. Click the Results  driver.

  2. In the Compare column, check the box next to each activity desired.

Printing Charts

Charts can be printed to paper or to PDF. To generate a chart as an image (.png, .jpg, etc.), it is recommended to take a screenshot using your operating system.

When printing to PDF, it is recommended to choose "Adobe PDF" rather than "Microsoft Print to PDF" for best results.


  1. Click the Results  driver.

  2. In the toolbar above the Chart pane, click the dropdown next to Chart Type and choose the desired chart.

  3. In the toolbar above the chart, click the Print button.

  4. Customize using the operating system's print window and click OK.

Portions of a chart can be printed by hovering over the chart with the mouse and zooming in using the scroll wheel.


Exporting Percentile Results to P6

Percentile data, or p values, can be exported to XER user defined fields (UDFs) for importing into P6. In P6, this data can be used to illustrate, for example, the entire schedule on P80 dates, side-by-side with the deterministic schedule on the Gantt chart. 

When exporting out of P6, UDFs must have data for at least one activity to be included the export.

  1. Click the Results  driver.

  2. Click the Export icon above the table and choose Export Percentile Results to P6 XER.

  3. Click the Add button and customize as desired.

  4. When finished, click Export.

  5. Enter a filename and click Save.

P values can only be mapped to UDFs of the same type. For example, a start date CANNOT be mapped to a finish date UDF, or vice versa. Nor can it be mapped to cost, indicator, integer, number, or text.

 Glossary

Distribution: a range of possible outcomes (e.g. durations, impacts, etc.) together with their shape, from which a value will be sampled.

Drift: the amount of time an activity may be advanced before advancing the project start.

Iteration: one complete pass, from the beginning of the schedule to the end, whereby sampling of entered ranges is applied). All iterations taken together comprise a simulation.

P value: The value (date, duration, etc.) which was observed during at least X% of iterations. For example, the P80 Finish Date is the finish date observed during at least 80% of the iterations. To put it another way, 80% of the iterations completed on that date or earlier.
