We use both Google Analytics and Site Catalyst V15. Recently we have seen a big discrepancy in visits. We are experiencing extra 12-15% visits in Site Catalyst compare to Google Analytics. Historically, we saw around 4-5% difference, which is acceptable . Is there any reason for this increase?
If not, trend the visits report on both platforms and determine as close as possible the point to where you started seeing a larger discrepancy, and which platform rose or fell. Once you find out which platform made the change, ask around and see what changes were made to the implementation or site at that time.
This sounds like an implementation change might be responsible for the jump in discrepancy. I would also audit the technology used to access your site to determine potential differences in sources of traffic (i.e. browsers blocking javascript, increase in bot traffic, etc.).

Are you seeing the discrepancy for this month? Were you using SC14?
From 1st Nov, SiteCatalyst report suites are migrated to v15 platform. The visits calculation in v15 is different from that of v14. You will see more visits in v15 because v15 include the visits from visitors that do not accept persistent cookies.
