The SYMLOG "Most Effective Profile" (MEP) is a universal standard used to estimate the perceived and actual effectiveness of leaders, members, teams, and organizational cultures worldwide. As hard as we have searched, the empirical findings associated with this profile have not changed significantly in twenty five years.

When we began the original research in 1983 we did not have an MEP. We asked the first 180 people in our very heterogeneous sample about their view. At that point, we had the empirical MEP from 180 people. Of course, we were not too confident with this measure and continued to collect data.

In 1987 we had expanded the number of observations to about 4000 people from many cultures and countries. What we found is that we needed to adjust the normative profile on the bargraph by at most 1 or 2 x's given the new information. None of these few slight adjustments were of statistical significance.

By 1990 (and then again in 1995 and 2005) we again searched our data banks in order to make needed adjustments. As it turns out, our original sample of 180 was extraordinarily prescient because we have not found any empirical evidence which indicates a need to make further adjustments.

In other words, there is a remarkable stability in the original findings. As hard as we try to update for time, space, race, country, political situation, type of industry, et cetera, the findings remain the same:

What are the findings? The SYMLOG MEP is an extremely robust standard for an estimate of "Most Effective Profile" as people interact and work together.
