deadlinemiss

Deadlinemiss is a term used in project management and software development to describe the failure to complete a task or deliverable by its scheduled deadline. As a noun, it denotes the event of missing a deadline; as a verb, it can be used informally to describe the action of missing a deadline. The term is a blend of “deadline” and “miss” and appears in discussions of schedule risk and performance, often alongside other jargon describing delays and overrun.

Origins of deadlinemiss are informal. The term shows up in online discussions, blog posts, and some internal corporate communications as a shorthand for overdue work. It is not part of formal project management standards and is less common in official documentation. Its usage tends to occur in contexts that emphasize time pressure, accountability, and quantitative metrics, where organizations may track deadlinemiss events, response times, and root causes.

In practice, deadlinemiss is used to categorize overdue tasks within dashboards and reports, enabling teams to flag schedule risk and trigger corrective actions. Typical responses include re-prioritizing work, rebaselining schedules, adding buffers, reallocating resources, or implementing process improvements to improve estimation accuracy and reduce future deadlinemiss events. Some organizations measure a deadlinemiss rate to monitor performance over time.

Criticism of the term notes that it is informal jargon and may reduce clarity in formal communications. Many practitioners prefer the terms “missed deadline,” “deadline overrun,” or “schedule slippage” for precision. See also: missed deadline, deadline slippage, schedule risk, project management.
