Lifetime and its Evolution Process over Generations

  title={Lifetime and its Evolution Process over Generations},
  author={Tetsuo Tamai and Yohsuke Torimitsu},
Software evolution process does not end at the death of an individual software system but usually continues its evolution over generations through being replaced by newly built software. To explore this research topic, we conducted a survey collecting data of software lifetimes, replacement practices and factors of replacement. In this paper, we report the results of the survey and discuss some possible long range strategies for software life cycle planning and control based on our findings.
