2I'm not sure either choice is the best way of phrasing this. Please can you give the whole sentence you would like to say? As to a general answer to your question, yes you can use the pattern plural noun + plural verb + singular noun. In many cases, however, I find that it sounds awkward and would be better if phrased differently. – SteveES – 2017-05-23T12:50:46.933

Thanks @SteveES here is the whole sentence : "Processes are an integrated set of activities that are done in order to achieve a single objective." I'll be happy if I learn a better way for saying this : ) – aghArdeshir – 2017-05-23T12:55:10.730

2I don't understand what you are trying to say, if you can explain it in more detail that would be helpful. Do you mean that each individual process is made up of a set of activities? Or that multiple processes are integrated into a set of activities? Or something else entirely?! – SteveES – 2017-05-23T12:59:17.970

WHOOOOOOOOOOO.... seeing your comment made me fix my mindset. +100. Actually it is documentation of a software. It has something to do with some BPMN charts. It Doesn't matter. I was trying to imply a set containing of some activities. Each set is a process. So Processes are more than a set. Now I see.. I should simply just say "Processes are integrated sets of activities that are done to ..." . right ?

Thanks @SteveES . It was so helpful and life-saving. : ) – aghArdeshir – 2017-05-23T13:25:27.090

2Just to double-check... Does your statement applies to all processes individually (rather than all processes together, or only some processes; would it be equally true to say a process is... about any process)? Also, do you mean 1 process = 1 set of activities; 1 process = multiple sets of activities; or 1 process = (at least) 1 set of activities + some other stuff? – SteveES – 2017-05-23T13:34:49.530

WOW! That opens a door to lots of things. I like how you are "DETAILSISTIC". : ) - YES! my statement applies to all process individually, meaning each process is a set of activities (and YES) among other things. e.g.: 1 process = 1 set of activities + some other "minor" stuff. I love to know where it goes, but by the way I think I will go with "Processes are integrated sets of activities ...". Thanks . – aghArdeshir – 2017-05-23T13:59:30.340

2I would advise being as precise and unambiguous as possible in technical documentation. I would therefore advise using "Each process is..." or "Each process consists of...", as this makes it clear that it applies to all processes, while also allowing you to clearly state what a single process involves. Saying "Processes are integrated sets..." leaves it ambiguous as to whether a single process contains 1 set, or contains multiple sets. – SteveES – 2017-05-23T14:24:46.733
