This document discusses lean management and startup methodology. It begins by defining a startup as an organization designed to deliver a new product or service under extreme uncertainty. It describes the empirical and iterative process of testing hypotheses and adapting based on results that startups use rather than the waterfall management approach of more traditional companies. The document then explains how scrum, the startup's preferred management style, uses transparency, inspection, and adaptation as its three pillars. It provides details on how scrum works through the use of stories, backlogs, sprints, daily standup meetings, and sprint reviews to monitor progress in an iterative process.
