Agile Manifesto: Principles of Modern Software Development
Examine the Agile Manifesto's core values, principles, and critiques from its authors about modern practices.
What was corrected
Article embellished an Association for Project Management survey finding, attached a specific precise productivity figure to Jeff Sutherland's book that could not be verified in his documented claims, described a specific research finding attributed to GitLab and Buffer's remote-work reports that could not be verified in either, misdated a Haystack Analytics burnout survey and altered one of its statistics, distorted McKinsey Digital's technical debt research, misattributed a feature-usage statistic partly to 'Pragmatic Marketing' (both figures actually trace to the Standish Group), cited a 2021 meta-analysis by 'Diebold, Ostberg, Wagner, and Zendler' that could not be verified, and misattributed a Scrum-usage statistic to a Scrum Alliance survey when it actually comes from Digital.ai's State of Agile report.
Softened the APM claim to match its actual published finding, replaced Sutherland's specific figure with an accurate description of his book's argument and its case-study-based support, replaced the GitLab/Buffer claim with an accurate description of what those reports actually document, corrected the Haystack Analytics survey's year and the misattributed statistic to reflect its real finding (pandemic-worsened burnout, not overwork as the stated cause), corrected the McKinsey Digital description to match its actual technical-debt research framing, corrected the unused-features statistic to attribute both figures to the Standish Group, removed the unverifiable meta-analysis citation while preserving the general research consensus it was meant to illustrate, and corrected the Scrum-usage statistic's source attribution to Digital.ai.
Why this is better
Verified against PMI's Pulse of the Profession reports, the APM's published 2022 agile research, Haystack Analytics' original 2021 burnout study, McKinsey Digital's published technical-debt research, Standish Group feature-usage citations, and Digital.ai's State of Agile report series; no corroborating source could be found for a 2021 Diebold, Ostberg, Wagner, and Zendler meta-analysis of 44 Agile studies.
