1. The development and use of two successful electronic decision aides Presented By Dr. Matt Stockton June 10, 2013 University of Nebraska-Lincoln West Central Research Extension Center

2. My biggest fear has always been that I would develop a tool that didn’t fit the task and/or was so complicated that it required more investment by the user than the value they perceived they gained

4. The Process A recognized need Develop a methodology to answer the need Create the tool using the methodology Test and validate the tool Release the tool for use Use the feedback from the use to continue to improve and develop the tool

5. The recognized needs Deciding which feed is the best buy, depending on how I will use the feed ( energy, protein or DM source) (FCC) How many cows can be grazed on a specific corn field and/or for how long depending on their size (CSC)

6. The Tools The feed cost (FCC) and the corn stalk (CSC) “Cow-Q-Lators” –Both have come from a recognized need –Both are very practical in there application –Both contain information that is commonly needed and highly useful –Both are simple to apply and easy too learn

7. The FCC Answers three questions at three levels –Establishes feed cost considering transportation, storage and feeding cost and efficiency –Provides a comparisons among costs for 4 feeds at a time –Calculates feed needs based on time, feeds and ration fed

8. The CSC Can be used to calculate field rental rates or cost estimates of cattle based on –Animal size –Acres available –Number of animals –Management parameters –Corn yield

9. Access

10. Tools are currently available as downloadable microsoft excel spreadsheets Spread sheet information is limited to simple information users have or can obtain Spreadsheets are generally one page

11. Future Access As an app As an online tool not needing excel
