I guess i dont understand how you can devise new strategy for your clients if you havent properly analyzed how your previously recommended strategy succeeded. Isnt it an iterative process, not a "one and done"?
Or are you saying that is someone else's job? Or that there are parts of the analytic process that are needed for strategizing, but are otherwise unnecessary (and time-consuming) as far as you know? Are there ways to mechanize the analytic process?
I guess im looking at ways you can offer your boss solutions to the problem you presented. I always heard, never bring your boss a problem without having a solution for it. So, what is the BUSINESS problem here, not your dislike of your task.
