Excel Spreadsheet Linking

DPL is a standalone application that also integrates closely with Excel, providing the best of both words: a full featured graphical modeling interface paired with a familiar Excel environment that can efficiently deal with data and financial calculations.

You can build your decision tree model first and then set up Excel links or quickly build a DPL model from an established cash flow spreadsheet in just a few clicks. You can also create a local DPL model by keeping all the calculations wholly within DPL. It’s up to you!

Sensitivity Analyses

You can easily build a DPL model from an Excel cash flow spreadsheet. Starting with this basic model you can conduct sensitivity analyses to determine which variables have the biggest impact on value and decisions.

Through several types of tornado diagrams, DPL can help you build insight and prioritize your focus on what matters most.

DPL Results & Outputs

We understand that a model will only lead to action if the results can be understood and explained to the project team and stakeholders – which is why DPL offers a broad range of attractive and presentation-ready results that will provide you (and laymen) with maximum insight. These include but aren’t limited to:

  • Policy Tree: an unfiltered output tree that identifies the winning strategy and provides a complete picture of all the possible scenarios of the model
  • Risk Profiles: also known as a cumulative probability distribution, the Risk Profile output visually describes the range and likelihood of outcomes in your decision model
  • Value of Information/Control: Understand how much you should invest in further research, how much value there is in delaying a decision or the value of putting control systems in place
  • Endpoint Database: Record and save endpoint values in order to conduct “what if” sensitivity analyses without having to re-run the full model.
