Hello everybody,

In the past few years, I never have any real planning before starting a system, I know it's a waste of time and the system will never be good enough.

Now, not only cause I want to have my work done easier/better, i also need to cooperate with other programmers. I need to present the system design and communicate with them effectively. Someone told me UML is the way to go, but I'm not sure if it's suitable for our systems.

For example, an accounting system written in VFP, all functions are put in the menu bar for users to choose (Most of our VFP programs are in similar structure).
I need documents to:
(1) present the system to customers,
(2) let other programers know what to do without telling them everything by myself, and
(3) let other programers to follow the job easily even when the old programers are left.
Should I use UML? Does UML suits VFP products? We need a standard to follow when designing any new systems in the future.

Any suggestions or ideas will be greatly appreciated, and suggested readings are welcomed too :)

thanks a lot!
Jimi
