For example, let’s say that your washing machine at home broke down and you need to fix it. Instead of calling the handyman to come, your husband decides he’s going to fix the machine. He ends up spending half a day figuring out the machine, and does eventually fix it. He did however have to make a trip to the tool shop to buy some extra tools and parts for the machine. Now, if you had called the handy man, it would probably have taken the handyman much less time, and he would have all the necessary tools and parts already, because that is his job. So in this instance, was your husband’s time and effort worth it? Oh, and because he took half the day fixing the machine, you now had to take over his duties of dropping the kids off at soccer and swim practice.
These little jobs are done by people who log on to a company’s site and choose tasks, which could be as simple as clicking a link. Amazon's Mechanical Turk is one of the most well-known sites of this type. Also, there are crowdsourcing projects, which are similar to data entry, where companies engage an army of virtual workers to each do one small part of a larger project.
