It has the risk of being a B-team but it's also a good way to onboard new hires. You get a much higher turnover rate of new things to try, do, and learn. One place I worked did communications generation (PDF letters etc), we had massive clients and 300 hour projects and we had 3 hour simple letters. Churning those small ones out was the best way to get me to learn when I signed up. Just as long as someone sensible and experienced is watching. And some people just don't gel well with project marathons - I'm definitely a sprinter who loses focus on huge projects despite my years of experience. I'd rather do a lot of small ones.

It eventually got sold to a bigger more respectable company and those 300 hour quotes crept up north of 1000 hours and it was impossible to finish any job in under 10 hours but that's another story about internal red tape.
