In the The early 20th century, Frederick Taylor claimed developed "Scientific Management." Taylor was an engineer and tried to adjust the scientific way of thinking to management. His approach was the great work and remarkable.

However, if when trying to adjust apply scientific management to the a real business, many problems were happened occurred. Because human beings are not machines, workers feel pain and stress while with completely planned and calculated working.

Scientific Management has meanings methods for measuring the quality of working, but Scientific Management is not enough for running the a real business.

Hi Kuu3,

I'll try to explain some of the corrections, hopefully that helps:

"claimed" - This is usually used when you are taking ownership of something that already exists. For example, if there was a cookie on the table and I "claimed" it, that means it's mine. :) In this case, Frederick Taylor made something new, so I used "developed".

"the great work" - By saying it's remarkable, you are already saying that the work was great, so I just took this section out.

"However, if" - I changed the "if" to "when" because it sounds like he actually tried it. "If" could make it sound like he planned it, but never actually tried.

"adjust" - I changed it to "apply" because to adjust means that you're changing something. Apply means that you're using it. For example, you could apply a wrench to a nut to changed something, like Taylor applied Scientific Management to a business.

"the real business" - I changed it to "a real". If we were talking about the specific business he applied it to, I could use "the", but since it could have been any business, I used "a".

"were happened" - You can take out "were" completely. "Happened" can be used, but "occurred" sounds a little more formal, which matches up with the rest of the writing better.
