The phrase refers to foregoing time-consuming and often unproductive preliminary activities in favor of directly addressing a technical specification (TS). For example, in software development, this could mean bypassing initial, less critical planning stages and immediately focusing on coding based on detailed specification documents.
This direct approach can significantly accelerate project timelines and reduce wasted resources, particularly when the specification is comprehensive and well-defined. Historically, this methodology gained traction in environments emphasizing rapid prototyping and iterative development cycles, prioritizing tangible results over extensive upfront deliberation.
