cuz the analysis part worths the most, almost half of the whole case analysis, so u should pay most attention to it. usually for every alternative, u should start with a clear explanation of wat ur alternative means to the company, why it can solve the problem and a brief general idea of how to implement it in the company. after dat, use the bullet form to analyze all the pros and cons of the alternative. the give the conculsion whether or not it is a good alternative. if u r double spacing ur report, uaually one alternative is about one and half to two page page in length if u r asled to write a 20-page report
