When it comes time for you to get some groceries, what do you do? 

If you  are like most of us, you jump into your car. Drive to the grocery  store. Shop for what you want and buy it. Then you jump into your car  again and drive home. It turns out that this is a really inefficient way  of going about doing things and the product managers at grocery stores want to make some changes. 

However, in order to make those changes they are first going to have to update their product development definition and invent some grocery delivery robots.
