@ anon – it’s a good point you make, and given the wide range of classes available in most business courses, it seem strange that there is not even an elective that focuses on use of standard business software, writing good management reports etc (its somewhat ironic that most academic dissertations are party targeted on the number of words taken to express themselves – the exact opposite of what the business world wants!)
To be fair, it is the same in a number of other professions. Legal degrees normally include NO preparation of the process of bringing a case to court or serving papers on someone, etc. Accountants do a degree and then have to qualify. Even doctors, although they spend time in hospitals before qualifying, then have a very structured supervised progression.
Its easy to laugh at powerpoint, but I use it almost every day and often turn in business cases for millions of pounds which hinge on the three page ppt that summarises all the key points that would otherwise be hidden in a 20 page standard format business case.
The ability to explain a complex set of issues in a single page (and preferably with a picture) is an important skill.
