Sensitivity analysis can help you determine which of your input assumptions are critical.  \nBefore using the SensIt options, you must have a spreadsheet model with one or more inputs and an output. With SensIt it is easy to see how sensitive the output is to changes in the inputs.  \nIn Windows Excel 2007 & 2010 & 2013 & 2016, SensIt adds two items to the Add-Ins ribbon: SensIt One-Input Plot (Control+Shift+P) and SensIt Tornado-Spider (Control+Shift+S) .  \nIn Mac Excel 2011, SensIt adds the same two items to the Tools menu: SensIt One-Input Plot (Option+Command+p) and SensIt Tornado-Spider (Option+Command+s) .  \nIn Mac Excel 2016, run SensIt using the shortcut keys: SensIt One-Input Plot (Option+Command+p) and SensIt Tornado-Spider (Option+Command+s) .  \nUse SensIt’s One-Input Plot feature to see how your model’s output depends on changes in a single input variable. This feature creates an XY Scatter chart type.  \nUse SensIt’s Tornado-Spider feature to see how your model’s output depends on ranges you specify for each of the model’s input variables. This feature creates tornado charts (an Excel Bar chart type) and a spider chart (an XY Scatter chart type). The spider chart is useful for detecting anonlinear relationship between the input variables and the output variable of your model. The twofactor tornado chart can help you determine how your model output is affected by each pair of your input assumptions.  \nAll of SensIt’s functionality, including its built-in help, is a part of the SensIt XLAM file. There is no separate setup file or help file. When you use SensIt on a Windows computer, it does not create any Windows Registry entries (although Excel may use such entries to keep track of its add-ins) .  \n4.2 EXAMPLE PROBLEM  \nThis example is a simple economic model of a prospective new product taken from the Eschenbach (1992) article. The model assumes that the FirstCost investment occurs at the start of the first year and all subsequent cash flows are end-of-year. The product life is N years with the  \nSalvage value at the end ofyear N. At the start of the project there is no revenue for the first NNoRev years with subsequent annual Revenue during years NNoRev+1 through N. FracComp is the fraction of Revenue lost to competition. Annual operations and maintenance cost O&M applies for all N years of product life. The discount rate i is used to determine PresentWorth. Eschenbach uses the notation P/A,i,N and P/F,i,N, respectively, for the uniform periodic and the single payment present worth factors. The spreadsheet model includes some intermediate variables for determining various discount factors.  \nFigure 4.1 Model Display  \n\n|  | A | B |\n| --- | --- | --- |\n| 1 | Input Variables | Input Cells |\n| 2 | FirstCost | $120,000 |\n| 3 | Salvage | $20,000 |\n| 4 | N | 12 |\n| 5 | i | 10% |\n| 6 |  |  |\n|  | O&M | $6,000 |\n| 7 | Revenue | $55,000 |\n| 8 |  |  |\n|  | NNoRev | 1 |\n| 9 | FracComp | 0.2 |\n| 10 |  |  |\n|  | Intermediate Variables |  |\n| 11 | P/F,i, N | $0.32 |\n| 12 | P/A,i, N | $6.81 |\n| 13 | N-NNoRev | 11 |\n| 14 | P/A,i, N-NNoRev | $6.50 |\n| 15 | P/F,i, NNoRev | $0.91 |\n| 16 | Revenue Discount | $5.90 |\n| 17 | Output Variable |  |\n| 18 | Present Worth | $105,293 |\n\nFigure 4.2 Model Formulas  \n\n|  | A | B |\n| --- | --- | --- |\n| 10 | Intermediate Variables |  |\n| 11 | P/F,i,N | =1/(1+B5)^B4 |\n| 12 | P/A,i,N | =PV(B5, B4,-1) |\n| 13 | N-NNoRev | =B4-B8 |\n| 14 | P/A,i,N-NNoRev | =PV(B5, B13,-1) |\n| 15 |  |  |\n|  | P/F,i,NNoRev | =1/(1+B5)^B8 |\n| 16 | Revenue Discount | =B14*B15 |\n| 17 |  |  |\n|  | Output Variable |  |\n| 18 | Present Worth | =-B2+B3*B11-B6*B12+B7*(1-B9)*B16 |\n\n4.3 ONE INPUT, ONE OU","cbCaicCJl8e2Fqri","https://ap.wps.com/l/cbCaicCJl8e2Fqri","pdf",407666,17,"English","# SensIt Overview\n## Example Problem\n# One Input, One Output\n## Cells for Input Variable\n## Cells for Output Variable\n## Input Values","[{\"question\":\"What models are required before using SensIt options?\",\"answer\":\"A spreadsheet model must contain one or more input variables and an output variable.
