Which methodology to use?

[kyros]

Hello Everyone;
I am asked to draw dfd for Employee Monitoring System. Before it, there is a question about the methodology that I should use. I think it is more likely to use Waterfall model, because of the time schedules in the system. Anyway, I might be wrong, can you give me an idea about the design of the system.

A data flow diagram describes certain aspects of the design of a system. "Waterfall" is a software development methodology, which describes the process by which the system is built. I think you're comparing apples and oranges here. No matter what development methodology you use, you'll be able to create a DFD to describe your product.

Thanks for your reply, but you might misunderstood my question. There are two questions. First of them is " Which methodology would you use for that system?" The other one is to about data flow diagrams.

Oh, sorry, I read that as a single question. It does make more sense as two :)

Are you able to share a more detailed description of the system you're designing? In particular, what activities are you monitoring, and how often? Is there a reporting requirement? For both the data flow and development methodology questions, a lot can depend on the requirements you have (or sometimes, don't have). Also, do you have any scheduling constraints--i.e., how much of it do you have to deliver, and when?
