The many–hands problem makes it difficult to determine who should be held accountable for mistakes since:
a. one person in the project will always work on many different aspects of the project.
b. there will always be one person working on one part of a project at a time.
c. there will always be more than one person working on a significant project.
d. everyone in the project will always work on every aspect of the project, allowing everyone to know all the details about the project.

using the following data:
"often, unless a company is small, the completion of computer-related projects necessitates the involvement of numerous people, usually working in teams. in such situations, most likely, no single person will be completely well-versed in every aspect of an entire project - it is likely that he/she will be specifically familiar with the component with which he works. this makes it tricky to discern who or how many should be held responsible, liable, or accountable for wide-ranging and/or grim mistakes. this quandary is commonly referred to as the many-hands problem."
