ANECDOTE

The Ideal Days Misunderstanding

  • Chris Sims' team used "ideal days" for estimation instead of story points, which measured time as if no interruptions happened.
  • A VP misinterpreted this as the team only working 2.5 days a week, causing misunderstanding and reputational damage.
ADVICE

Communicate Methods Transparently

  • Always socialize your team's working methods widely, especially with stakeholders unfamiliar with agile terms.
  • Communicate in ways that leadership understands, focusing on outcomes and delivery timelines, not internal tools or jargon.
INSIGHT

Agile Terminology Impacts Acceptance

  • Agile terminology can create barriers when misunderstood by outsiders, impacting acceptance and trust.
  • Names like "Extreme Programming" or "Scrum Master" carry connotations that may hinder mainstream adoption, so careful messaging is critical.
