It started with a problem.
Before printed newspapers, employment was arranged through personal recommendation, craft guilds, labor exchanges, and direct inquiry at workplaces. As newspapers became widely distributed in the eighteenth and nineteenth centuries, employers began publishing notices for wanted workers. The Times of London printed employment notices in the late eighteenth century. By the mid-nineteenth century, the classified advertisement for jobs was an established feature of daily newspapers in Britain and the United States. Writing a job advertisement required articulating what was needed in a way that could be understood by a stranger — a discipline that revealed ambiguities in the role itself.

The job advertisement standardized the description of labor requirements. An employer had to specify what skills, experience, or attributes were expected — information that was often implicit when hiring through networks. This specification made the role legible to people outside the employer's existing relationships, expanding the candidate pool. It also made hiring less dependent on social proximity to the employer. The classified ad sections of newspapers grew to be significant sources of newspaper revenue in the nineteenth and twentieth centuries. The transition from newspaper classified ads to online job boards in the late 1990s and 2000s further expanded reach while preserving the underlying structure: a published description of what is sought.
What a builder can learn.
Our interpretation: writing a job advertisement is an act of clarification. Most small businesses that struggle to hire struggle to describe exactly what they need. The advertisement forces a decision: what skills, behaviors, and results are required? When a business cannot answer this precisely enough to publish it, the hiring process is often a search for the right person rather than a test against defined criteria. The discipline of writing the advertisement — even if never published — often clarifies what is actually needed.
A door still open.
A hypothesis worth testing: if a small business wrote a detailed job description for its next hire before it began looking, and shared the draft with an existing employee in a similar role to check its accuracy, what discrepancy would it find between the written description and the role as it is actually done?
If you had to describe your most needed hire in enough detail that a stranger could decide whether they were qualified, what would you have to define that you have not yet defined?
