&gt;I think this is when a manager is supposed to add resources.<p>No, no, no, a thousand times no. Software isn&#x27;t an assembly line. It&#x27;s not piece work. Adding more people to a late project only makes it <i>later</i>, as the existing dev team has to work to bring the new hires (even if they&#x27;re experienced developers, they&#x27;re still new to the project) up to speed. Adding more resources to a late project, without accounting for a period of reduced productivity is the absolute worst thing management can do. I have literally seen projects go from, &quot;Well, it&#x27;s borderline, but we can deliver if we work weekends,&quot; to, &quot;There is no way we can do this by the delivery date,&quot; because management decided to add two new developers to the team.<p>The worst thing is, Fred Brooks published a book talking about this phenomenon in the &#x27;70s: <i>The Mythical Man Month</i>. And somehow, the lesson still hasn&#x27;t sunk in.
