Explanation

In Agile, the 'Tail' (also called the 'Release Tail' or 'Hardening Sprint' in some frameworks) refers to the period at the end of a project or release cycle dedicated to stabilization activities - beta testing, regression testing, integration, documentation, and defect fixing. It represents the work needed to finalize and ship the product after the main development iterations are complete. A 'Spike' is a time-boxed research task; 'Code Freeze' is a point in time rather than a period; 'Lag' is a scheduling term unrelated to this concept.
