actuarial models are super complex. i can see how the average person can make a serious mistake on one, but at the same time that mistake could cost the company millions and it is your job to get it right. why are you making the mistakes? is it lack of attention to detail? and if it is, is it just the way you are or are you distracted/unmotivated? the latter is fixable (if you even want to) but the former is not. also, please take this as friendly advice from someone who employs financial analysts (and not SF snark), but -i hope this isn't how you communicate at work. even if this jargon is pretty common in your workplace, it still gets tedious and for critical conversations (like performance reviews) you need to speak as plainly as possible. what i think you just said was "if i have experience with the task, the outcomes are perfect. however, my job requires me to have perfect outcomes even if the task is unfamiliar, and i don't do that well despite numerous attempts to improve."
Conduct not an issue, but my boss not satisfied with the outcomes on a specific project i've been working on-numerous errors. These errors are a result of my approach of thinking through the problem, implementation and self review. The past 6 weeks have been informal checkpoint sessions to correct this, and I have seen improvement in my approach to problems, but the outcome still shitty. They know there's plenty of tasks I have perfect outcome-familiar tasks, but there's a skill set mismatch as the job requires someone who can achieve robust outcomes in unfamiliar projects.
