Design Patterns in Software Maintenance: An Experiment Replication at Brigham Young University, Krein et al. (2011). Outcome recorded: mixed. "Our results both confirm and contradict the original experiment[...]the patterns question remains wide open. View paper
Design Patterns in Software Maintenance: An Experiment Replication at UPM - Experiences with the RESER'11 Joint Replication Project, Juristo & Vegas (2011). Outcome recorded: failed. Our results are inconsistent with the original experiment. View paper
Design Patterns in Software Maintenance: An Experiment Replication at Freie Universität Berlin, Prechelt & Liesenberg (2011). Outcome recorded: mixed. Only one of the results is statistically significant; it confirms the result of the original experiment stating that the simplified version of the GR program could be extended more quickly than the pattern version View paper
