Comparison of Some Methods of Cluster Analysis with SPSS

I have already a paper with 70 pages. Now I need another 5 pages to improve this paper.(to improve the beginning part and the ending part).
At the beginnig part,I hope you can put forward a goal.(What is the purpose of this paper? What are we doing in this paper?or We are solving what kind of promblem?)
I think the main purpose of this paper is analyze a case with 3 methods ( hierarchical method, K-mean-method and two-step-method) with SPSS. I hope you can write 1 more page at the beginning part.
At the ending part,(be more exact,at the end of the 3rd part,before summary) I hope you can write 4 pages about a discussion.
This discussion include : 1 What are the advantages and disadvantages of this 3 methods? 2. What conclusion we have through the case? 3.Whether the purpose of this paper (we pose at the beginning part) is completed?
