Trending @Accenture; Anyone here from PMO?
I need to understand how the lock-in process works. What is difference between soft lock and Hard future lock? What is RRD? Who all can access Abascus? In short the entire process - end to end till roll off.

Soft lock is when you are considered for a project as a potential. You are not yet confirmed for the project.
Hardlock is when you are confirmed to be working on the project.
When you are softlocked by 1 project, another project can also place a challenge soft lock. But the other project cannot directly hardlock you if you already have a softlock. The softlock must be removed from the 1st project, so that someone else can place hardlock.
Hard future lock is because you are currently already in a project & will be rolled off in future & from then on the new project hardlock will be implemented.
Your softlock details cannot be viewed by you. project managers can view it i believe.

I confirm @BlueCereal 's answer. I was in soft lock since the past 5 days and challenge lock for the past 2 days. 2nd one even though more suitable acc to my skillset couldn't directly Hardlock me, ended up getting hard-locked to the 1st one today. This one is also nice, just that I'll need to learn new stuff.

Most people tend to ignore questions if they find so many questions.
