Agile
A family of software-development practices that prioritise short iterations, frequent customer feedback, and adjusting plans as the work reveals what was wrong about the original plan.
Agile is older than most people realise (the manifesto is from 2001) and worse-implemented than most teams will admit. The original idea was simple: planning further out than you can predict is wasted work, so plan short, ship, learn, replan. Everything else (Scrum, Kanban, SAFe, sprints, retros, story points) is implementation detail layered on top.
The most useful question for a team that says it is "doing agile" is: when was the last time the plan changed because of what shipped last week? If the answer is never, the team is doing waterfall in two-week chunks.
Wavect is agile in the original sense: we work in short cycles, demo often, and we are willing to throw out work that turned out to be wrong. We are skeptical of the certification-industry version of agile, where the meeting cadence becomes the goal.
