Looking to buy a new car, a house, an HP calculator or a new telescope. Looking for the perfect job? The perfect employee or the perfect girl? Or deciding between a set of possible choices and having a hard time making up your mind?
There is a simple tool that I have used many times when faced with difficult choices (including that of finding the perfect girl). It requires you to simply list all the important items in a requirement specification and giving each item an importance or “weight” (any scale will do). And then as you are faced with each case to evaluate, give that case a score on each item in the list of requirements. A simple example:
If you are to recruiting a new employee, the specification would consist of items such as “relevant knowledge”, “relevant job experience”, “proven production record”, “communication skills” or “empathy”. You would give each item a certain weight where “relevant knowledge” could be given a weight of “4” while “empathy” for this specific job could be given “2” in weight.
When a requirement specification is populated with a list of weighted items, it’s time to pitch a set of cases against the specification. You figure out the scale you want to use and put a score on each item of the requirement specification for the case you evaluate. The scale goes from “0” to any number you set as the maximum score. A candidate for a job could score a “3” on “relevant knowledge” and a “5” on empathy on a scale from “0” to “5”. You then multiply the score with the item’s weight to get the “weighted score”. So even though the candidate receives a maximum score on empathy, she only gets a weighted score of “10” on that item compared to “12” on “relevant knowledge”.
Finally, you sum up all the weighted scores, divide by the sum of the item weights, divide by the maximum score and multiply with 100. Then you have a total percentage score of how well that case fits the requirement specification.
A tool? What do you mean with “a tool”?
You want a tool to help you create a requirement specification with a list of weighted items and then to easily manage and evaluate many cases against it?
Sure, I have that. Do you have an HP-41 calculator?
I know, I know. It’s a stupid question. Of course you have the best calculator ever made sitting right there on the table and in daily use no less.
Then I will supply you with this neat evaluation program utilizing a new trick; dynamic menus.
What’s that? Well, head on over to my calculator’s page and check it out. Choosing the perfect girl is at right your fingertips.
