The lean-stack take
For a lean Six Sigma team it models how input variation flows through to an output. Belts can test tolerances and settings in a spreadsheet model before changing the real process or design.
Best for
Six Sigma Black Belts and design engineers who already work in Excel and need Monte Carlo simulation and tolerance analysis.
Watch out for
It runs as an Excel add-in, so check the system requirements against your Excel version and operating system before buying.
About
About DiscoverSim
DiscoverSim is Monte Carlo simulation and optimization software that runs in Microsoft Excel. It is made by SigmaXL, Inc., which also makes the SigmaXL statistics add-in.
Written by lean-stack from DiscoverSim's public pages. Vendors can replace it with their own description by claiming this profile.
Features
What DiscoverSim offers
Monte Carlo simulation in Excel
DiscoverSim runs Monte Carlo simulation inside an Excel model. This supports design for Six Sigma and the Improve phase of DMAIC.
Optimization
Optimization menus and options let users search for input settings that meet a goal. This helps a team pick process settings with less trial and error on the floor.
Tolerance design
A case study covers multiple response optimization and tolerance design. This helps teams set tolerances that keep output inside the specification.
Variation reduction
A catapult case study shows simulation used for variation reduction. This fits training and projects that aim to center a process and cut its spread.
Project portfolio selection
One case study uses simulation to select Six Sigma DMAIC projects. It shows the tool applied to choosing which improvement work to fund.
SigmaXL included
The feature list page says DiscoverSim now includes SigmaXL Version 11. Users get the statistics add-in for SPC, capability and hypothesis tests with it.
Tutorials and workbook
SigmaXL publishes a getting started tutorial, several case studies and a DiscoverSim Version 2.2 workbook. These help new users learn the tool.
Lean techniques supported
The lean practices DiscoverSim is built to support.

- You teach variation reduction with simulation exercises
Look elsewhere if…
- You need live SPC on shop-floor data rather than simulation
- Your team does not work in Excel
- You need a cloud tool shared across many users
