I think it is very cost effective. The issue has always been that CA charges for the tool. It's like Microsoft gives away .NET and CA doesn't, so you're swimming upstream against people that see the initial expense as a big problem and don't look beyond that. The tool has been around so long now, approximately 25 years. Several companies have tried to replace it, and insisted they were going to replace it, but they weren’t able to.

I was not involved in pricing and/or licensing, which was managed by another team.
