Week 6 Reading Reflection

I think the biggest surprise in this article was the amount of barriers to entry he talked about. I've obviously heard of them before in different economics classes I've taken but I didn't realize how many there were. I had never gone in depth on them before and now understand that there are many different types that affect companies in different ways.
One thing I thought was confusing was when he talked about powerful suppliers. It's crazy how much influence one company can have just by making one decision. It can affect a lot of other suppliers and really prevent them from succeeding. It's confusing to understand though just what they are doing and how it changes the market as a whole. It's obviously a very well thought out process and is quite interesting.
The first question I would ask would be which barrier to entry he considers to be the biggest challenge for companies to overcome. There are several that he talked about but I wonder which is the one that makes the most people fail. I would also like to ask him if there are any stories similar to Dr. Pepper's. I think they have a really cool story as to how they were able to uniquely succeed in the market and I wonder if there are any other big names that also had unique successes.
One thing I thought I disagreed with was when he said selling to everybody can be bad for some producers. I guess that it's good to focus on one or two main groups to sell to but it's not at all a bad thing to be selling to everybody. That was the biggest thing I found that I disagreed with.
