This is our first ever Guestimation Challenge! It’s a game in which we try to make fast estimations with very little data. For example, estimate how many miles of highway does the US have? Players can only use a calculator, pen, and paper to come as close to the correct number as possible. Without the use of their computer or additional resources. This game imitates a real-world scenario, where we need to estimate numbers for our projects. For example, when we want to understand the size of our competitors, how much revenue our product or service idea could make, etc. The first two contenders are d.MBA mentors, Martina Skender (Innovation consultant) and Brian Wong (Business Designer at FJORD Accenture).
