Potential increases in interviewer productivity are a direct function of many variables including questionnaire length, incidence, sample efficiency and dialing mode. In additon, factors such as numbers of interviewers actively working on a survey, sample availability, acceptance levels of call abandonment, and response rate all influence actual productivity at any time. With that in mind, PRO-T-S® has been designed to guarantee the maximum throughout at all times given the limitations and guidelines imposed on any particular study.
The examples below are a representative sample of surveys conducted and cover a spectrum of incidences and questionnaire lengths, providing realistic examples of how PRO-T-S will increase production with little intervention:
Example 1: Customer Satisfaction Study: 8% Incidence. 3-4 minute screen. 22 minute questionnaire. Client bid the project at .3 Completes Per Hour; using PRO-T-S it came in at .59 CPH. He said he had "3 or 4" other projects that he had similar results with. The interviewers ask to be put on the dialer. 96% improvement.
Example 2: Calling customers who had recently made an inquiry to the business office The sample is, of course, very high quality and incidence is near 100%. The interview length is 5.18 minutes. They achieved a 51% improvement.
Example 3: Predictive tests: Cat/Dog Study. 16 CPH on power. 24 CPH on researchPredictive. This is a 30-second questionnaire used to test predictive dialing in a live environment.
Example 4: They ran a study on PRO-T-S and the same study with manual interviewers. PRO-T-S did 38.5% better then the other interviewers. Length of Interview: 15 minutes Incidence: 24 % Length of Screener: 4 minutes Type of Sample: RDD Number of Interviews: 300
Example 5: Weekly 1,000 interviews that averaged twenty-three (23) minutes, with an incidence of 94%. Dialings per hour were 20% higher in CATI-mode; completes per hour 19% higher, a rate of 1.41 per hour.
Example 6: Survey had a 6.5% incidence, with the screener averaging twenty-two (22) seconds. The 950 interviews averaged twenty-three (23) minutes. Manual dialing had a production rate of 0.38 per hour; CATI-mode 0.58 - a 53% increase in hourly production.
Example 7: Survey had a 95% incidence with approximately 2,000 interviews of ten (10) minutes length conducted in both CATI and manual dialing modes. CATI dialing produced a 68% increase in both dialings and completes per hour.
Example 8: In an analysis of over 1,700,000 PRO-T-S dialings, average time to a connect was 32 seconds compared to a manual dialing figure of 56 seconds - a 43% reduction.
Example 9: A competitor was getting one recruit in 3.2 hours. Our client, using PRO-T-S, increased the recruit rate to one per hour - a 320% improvement. It was costing $67 per recruit; he got it down to $19 per recruit.
Example 10: "I was totally shocked - they did almost 2 times better [than interviewers not using PRO-T-S]." Two suppliers doing the same syndicated project, manual vs. PRO-T-S dialing -. $13 vs. $8.75 per complete.
Example 11: “We will save $60,000 this quarter using PRO-T-S.” [Original system cost: $127,200.]
Example 12: "Without PRO-T-S, the job was costing $48 per interview. With PRO-T-S, the costs dropped to $22 per interview.
Of course, the actual mix of studies will determine the overall production gains, but even a modest 33% increase means that Proactive mode alone will provide full direct payback in four months or less.
