To start of, write down: - What is it that needs to be analysed? - How/where will this information come from? - How does it need to be displayed, i.e., do you need graphs or charts, or is a simple spreadsheet sufficient - Who needs the information, this will indicate the level of analyses required, i.e., for a high level person, the information needs to be well analysed and formatted, if it is for auditing purposes, then you might not want to analyse the data at all (rather pass it on to the auditors and let them take care of it) - Is there a schedule required, or is it only once off? - How should the results be accessed, from the web, emailed, posted, etc. (You should probably dump the results in a pdf format, in which case you can have a look a iTextSharp - I love this library!!! - After you have received the results, does the person reading the results require it to be modified, i.e, If I change this value, what would the effects be in 5 years time? - How important is speed? This will be determined by when the analyses should be done, if it is a nightly batch job, then speed is not that important, anything else, speed is important. - The program itself, is a console application sufficient, or should it look pretty? If prettiness is a factor, look at WPF or Silverlight (depending on whether it is web-based, or standalone). This will also indicate the speed/performance. - Do you need additional hardware, such as a more powerful server that can take the processing punch This is all I can think of, but based on what you provided, this would be a good place to start. Based on your assessment - or, requirements analysis - you should then look at technology.
