Advantages / disadvantages of expanding product range?
Expanding product range can increase revenue and may increase profitability. I said may, because the introduction of new range may entail additional resources and the profit contribution may not be able to justify its cost. But then if your capacity to produce existing range will be compromised by the addition of a wider range, the net profitability effect could also be affected. A thorough study is necessary.
What are the disadvantages to having a house vinyl sided?
As you can see from the previous posts, vinyl siding is one of those materials that some people love and others detest. That's because 1) there's a wide range in the quality of vinyl siding available, and 2) there's a wide range in the quality of installation. The quality of installation is especially important in re-siding an existing house, and even an excellent product will eventually look bad if installed by a slapdash contractor. Here's something that should help you to make up your mind: http://www.thisoldhouse.com/toh/article/0,,266296,00.html?xid=yahoo-answers&partner=yes
What are the advantages of having several Christian denominations?
In my opinion, there are no advantages. Unless you happen to believe that Christianity has nothing to do with God. Then they allow you to pick the religion that best suits you. But if you believe that God is behind the work, then how can they all be correct? And, using the "how can they all be correct?" question, it stands to reason that most, if not all, of them are wrong. Therefore, there are no advantages, and, in my opinion, some very big disadvantages. If one believes in God and one believes that there is opposition to God in this existence, then those that are wrong are part of the opposition. I do _not_ consider those who are members of the opposition to be bad people and I do believe that they have many truths and I do believe that they are doing their best to live according to their understanding and that God will reward them for their efforts and attitude. (All are saved--this is beyond salvation) Again, my opinion on this question, so your mileage may vary.
