I'm quite new to computer and I've been asked to advise on which Program to choose for a company-Off-the-shelve application package or Bespoke Application package. Please help me to give a very meaningful answer as to the advantages and disadvanges each have over the other.

Thank you.

If by "bespoke" you mean "custom made", then it depends on what you want to do. What is it that you need to do with the application?

To give an example of why the application is important, If the application is "word processing", then you can settle for an off the shelf product, as there are many applications that offer word processing, Microsoft Word to name just one.

However if the application is "synchronisation of rocket launch procedure", then that one is probably better off being bespoke.
