What’s In Your Toolbox?

• Lots to choose from…• 2014 KDnuggets Software Poll – 69 used in real projects*• “You need to be familiar with different tools, but you also

need to be able to use them. A lot of tools have tutorials available. You have to be able to use the tools to solve real problems. That being said, there is not enough time to become adept at everything. Choose carefully.”

• Balancing excellence with comprehensiveness • But still do something useful

• Compatibility with your team and company

From Mike McUne

What Do Employers Value?• Still being decided…

• “Unfortunately, I do not know if there is an answer to this yet because (1) we are in the very early innings, (2) the technology is rapidly evolving, and (3) the business usage of analytics is exploding into all kinds of new areas.”

• Depth versus Breadth?• Specialist or generalist?• Small toolbox or large toolbox? • Deep industry smarts or cross-industry savvy?

• Degree, certificate or track record?• Document your abilities. Build your portfolio!

• “Pro-bono consulting groups, such as Code for Colorado”• Regardless… “Stick to a focused plan”

From Scott Oetting

In Summary

• Lots of resources! Perhaps too many?• Learn and then do• Depend upon your community• Choose your toolbox wisely• Document your abilities for desired employers• Need to get serious & stay focused
