Just as I was making good progress with data feed testing, my client has requested that I focus more on another part of the system to deliver that before or with some of the new feeds.
So I start with near zero specifications, then we have some helpful meetings and slowly I think about 1/3 of the requirements are now outlined.
So I'm back to spec'ing up a project and extracting requirements from hand written notes, emails and wiki rambling.
anyway.. I found some useful tools and pages along the way :
* http://wwwhome.cs.utwente.nl/~tcm/ ( Toolkit for Conceptual Modeling - data flow diagrams, flow charts, state diagrams)
* http://www.itteam-direct.com/gwssadm.htm ( free SSADM / DFD tutorial)
* http://www.systemsguild.com/GuildSite/Robs/Template.html ( template and guide for requirements )
All of which have been quite helpful.
