Curbing Resource Consumption Using Team Based Feedback


Published on

This work details a team-based feedback approach for reducing resource consumption. The approach uses paper printing within office environments as a case study. It communicates the print usage of each participant’s team rather than the participant’s individual print usage. Feedback is provided weekly via emails and contains normative information, along with eco-metrics and team-based comparative statistics. The approach was empirically evaluated to study the effectiveness of the feedback method. The experiment comprised of 16 people belonging to 4 teams with data on their print usage gathered over 58 weeks, using the first 30-35 weeks as a baseline. The study showed a significant reduction in individual printing with an average of 28%. The experiment confirms the underlying hypothesis that participants are persuaded to reduce their print usage in order to improve the overall printing behaviour of their teams. The research provides clear pathways for future research to qualitatively investigate our findings.

Digital Enterprise Research Institute www.deri.ieResults: Statistical Significance Difference sample normally distributed The Anderson-Darling test P-value = 0.343 Q-Q plot confirms normality Paired t-test Standard level of significance alpha = 0.05 P-value = 0.025 It is statistically significant to say that the feedbackmethod helped decrease the individuals’proportional printing after it was applied14 / 20
  15. 15. Digital Enterprise Research Institute www.deri.ieTeam Level Printing All units except unit 2 reduced overall unit printing.15 / 20
  16. 16. Digital Enterprise Research Institute www.deri.ieDiscussion Previous survey revealed three themes Theme 1 Any printing conducted by staff was viewed as necessary,excepting accidents. Theme 2 Staff viewed different metrics as relevant or alternatively,as unnecessary for feedback on printing behaviour. Theme 3 Staff viewed co-workers championing reduced paper useas a helpful reminder to be conscious of how much theywere printing.16 / 20
  17. 17. Digital Enterprise Research Institute www.deri.ieTheme 1 All printing is necessary About 31% of the participants – showed a slightincrease in their proportional printing Likely that the driving force behind the non-responsive people is Theme 1. Any feedback method needs to address fully orpartially this theme to get better results e.g. by changing business processes17 / 20
  18. 18. Digital Enterprise Research Institute www.deri.ieTheme 2 Flavoured feedback Software in this experiment applied variousflavours in tandem Stating the same information in different ways thataddress different models of individual perception isin fact a good feature of feedback methods18 / 20
  19. 19. Digital Enterprise Research Institute www.deri.ieTheme 3 Comparison and competition Temporal comparison Contrasts team printing performance in a week toperformance the week prior. Social comparison Compares printing performance on a team-to-team basis Feedback method has been able to form anincentive for individuals to lower printing. Some teams did not respond Outliers exist and affect overall unit performance Future work: hybrid personal and team-based feedback19 / 20
  20. 20. Digital Enterprise Research Institute www.deri.ieConclusions Team-based feedback is persuasive. Applying several strategies in tandem helpsdecrease divergence of outliers TODO Study the effect of communities dynamics Test hypothesis with other types of resources: e.g. energyconsumption20 / 20
