Generalists are selected when evaluated by sum
2018-04-24
- Rating in Japanese] of multiple tests and multiple judges' scores will result in a person with better overall ability being rated higher than a person who excels in only some abilities.
- Therefore, you would choose generalist instead of specialist. ref. Specialists and generalists.
- If you want to hire specialists, sharp and talented, do not make such a selection.
On the right is the contour line when evaluated by the sum of the two test scores, and on the left is the contour line when evaluated by the maximum of the two test scores.
The evaluation of Mr. A, who scored 60 points in both abilities, and Mr. B, who excelled in one ability, are reversed.
relevance - Harmonized average of ranks to get the sharpest talent - This is an evaluation strategy for cases where absolute evaluation scores, such as tests, are not given, but only rank ratings are obtained.
What prompted me to write this article
- 2018-04-23 We want to raise the top 1% of children in Japan - a behind-the-scenes look at "unexplored junior" unexplored junior
--When I hear the word "unexplored", I get the impression that the projects that are selected are all of a high level. Please tell us about the criteria for the selection of the submitted ideas.
In the selection process for unexplored junior, each PM decides on the adoption of a project from the viewpoint of "whether or not I want to work with this girl". After screening the application documents, each PM conducts a 30-minute online interview with the applicant whose idea they are interested in, and decides whether or not the project will be adopted. Since each PM evaluates applicants from different perspectives and based on different criteria, there is not much overlap among PMs in the number of applicants they nominate for interviews.
-- I was surprised. I had imagined that all the PMs would evaluate all the ideas and adopt the applicants in order from the top to the bottom, using a point scoring system.
- Specialists should not be selected in such a way.
- Also, "point rationing system" does not mean adding up multiple ratings.
- Ignore the bad and focus on the good.
- On the right side of the above figure, when evaluating the sum of x and y, A (60, 60) has 120 points and beats B (100, 0)'s 100 points because B's -100 is not ignored when comparing A (-40, -40) and B (0, -100), which is a subtraction from 100 points.
- In other words, using addition to combine multiple evaluations is a neutral method that is neither additive nor subtractive.
- max(x, y) is an additive method that ignores bad points, min(x, y) is a subtractive method that ignores good points
PS
- [/masui/ sum and average](https://scrapbox.io/masui/ sum and average).
Summing is the same as take the average (the order is exactly the same because you just divide by a constant).
Since the majority rule is to take the greatest sum of each person's 0/1 ratings, the "sum rating" at issue here
relevance - Average orientation is the worst environment - Harmonized average of ranks to get the sharpest talent
