Excel Sizing Templates

Three MS Excel sizing spreadsheets are installed with SLIM-Suite that can be used standalone or linked to SLIM-Estimate workbooks via the Sizing Calculator.  This is the most flexible method, allowing unlimited sizing units, gearing factors, and uncertainty ranges for both.  Spreadsheets can be distributed to subject matter experts who are not SLIM users, so they can contribute to sizing efforts.

Three sizing methodologies are available:

  • PERT Decomposition
  • Prioritized Features
  • Relative Percentage

These spreadsheets are stored in the C:\user\Documents\QSM\Toolsxxx\Templates folder, where 'xxx' is your SLIM-Suite version number, e.g., 103. 

You may download the spreadsheets and other templates on the Downloads page.
