Study Finds 268% Higher Failure Rates For Agile Software Projects

Richard Speed reports via The Register: A study has found that software projects adopting Agile practices are 268 percent more likely to fail than those that do not. Even though the research commissioned by consultancy Engprax could be seen as a thinly veiled plug for Impact Engineering methodology, it feeds into the suspicion that the Agile Manifesto might not be all it's cracked up to be. The study's fieldwork was conducted between May 3 and May 7 with 600 software engineers (250 in the UK and 350 in the US) participating. One standout statistic was that projects with clear requirements documented before development started were 97 percent more likely to succeed. In comparison, one of the four pillars of the Agile Manifesto is 'Working Software over Comprehensive Documentation.'

According to the study, putting a specification in place before development begins can result in a 50 percent increase in success, and making sure the requirements are accurate to the real-world problem can lead to a 57 percent increase. Dr Junade Ali, author of Impact Engineering, said: 'With 65 percent of projects adopting Agile practices failing to be delivered on time, it's time to question Agile's cult following. 'Our research has shown that what matters when it comes to delivering high-quality software on time and within budget is a robust requirements engineering process and having the psychological safety to discuss and solve problems when they emerge, whilst taking steps to prevent developer burnout.' Projects where engineers felt they had the freedom to discuss and address problems were 87 percent more likely to succeed. Worryingly, workers in the UK were 13 percent less likely to feel they could discuss problems than those in the US, according to the study.
