I've had some Function Point Analysis documents available here before, and recently finished converting those presentations into a better form for the internet. To that end I've gathered all these in a new Function Point Analysis Education Center, which contains those free documents and presentations.
These educational documents cover FPA, cost estimating, and even cost estimating for Agile software development projects.
This website is a little one-man operation. If you found this information helpful, I’d appreciate it if you would share it.
