slapdashness

This term conveys a strong sense of negligence and haste, suggesting a complete disregard for precision or quality. It is typically used in a critical or derogatory manner to describe work that is superficially finished but structurally or logically flawed. It differs from simple speed by emphasizing the resulting lack of care.

As an abstract noun derived from the adjective slapdash, it is an uncountable mass noun. It cannot be pluralized and does not take a numerical modifier; instead, it requires partitive constructions such as a degree of slapdashness or an instance of slapdashness to quantify the quality.
