Patent ID: 8352309

Claim:
A method, comprising: displaying a percent question that requests a product evaluator to indicate how often an event occurs; in response to receiving a response to the percent question, requesting a first set of responses to a first list of subquestions and a second set of responses to a second list of subquestions, wherein the first list of subquestions is applicable when the event occurs and the second list of subquestions is applicable when the event does not occur, and wherein the response to the percent question represents a fraction; receiving additional responses to a plurality of additional questions, wherein the percent question, the first list of subquestions, and the second list of subquestions comprise a plurality of questions, and wherein the response to the percent question, the first set of responses, the second set of responses, and the additional responses comprise a plurality of responses; and determining, via a serviceability assessment program included in a computational device, a service time based on the plurality of responses to the plurality of questions, wherein the service time is determined based on the responses to the plurality of questions and the subquestions, a frequency value denoting a fraction of time when a question is applicable, and a question time value, wherein the service time is determined by adding a previous service time to a product of the question time value for the question and the frequency value, wherein the frequency value is updated based on a question fraction representing the responses to the percent question, a frequency of true subquestions, and a frequency of false subquestions, wherein the frequency of true subquestions is a product of the frequency value and a question fraction, and wherein the frequency of false subquestions is a product of the frequency value and the question fraction subtracted from 1.
