Heard from a friend regarding CEP:

1) In some organizations, Performance Grade & Current Estimated Potential are two different things.

What does this mean?

- Depending on organisation, the two "B" grading to promote may not be true. Some organisations even give out "A" but however will NOT raise your CEP at all.
- CEP is afterall a measure of your competency. You can be damn good at your job and get an "A" grade, but if you are not competent, your CEP will not be raised.
- Just because your CEP is raised, does not mean you will get the job if someone above you does not leave. You will have to wait until a posting upstream is available.

Hope that clarifies things.
