No estimates has the highest potential for improvement. Estimates are often wrong. In many organizations they are reliably wrong. Without spending time on estimates and wondering how to make them accurate, you can: * Make risk assessments: Which tasks are most likely to cause a schedule problem or where an implementation approach could fail. * Spend more time on retrospectives. Retrospectives are more valuable than estimates because the data is accurate.
