I've been wondering about this question for a while. I'm aware that Job Titles are not completely meaningful (specially, in the [financial][1] sector) but still, calling one as 'Project Manager' should represent a standard.

The Job Title usually goes along with the role the professional executes on his daily work. Controlling Scope and Schedule is the basics, and usually it implies in leading a team. However, there's one Constraint, the [cost][2], which - I believe - would differentiate a 'Team Leader' or a 'Project Leader' from a *real* 'Project Manager'.

Looking for the [PMI definition][3], it states that 

> (...) project management brings a unique focus shaped by the goals,
> resources and schedule of each project

which makes no clear reference to *costs*. In this same link, is mentioned the knowledge areas the PM is expected to cover, which are:

 - Integration	 
 - Scope	 
 - Time 
 - Cost	 
 - Quality	 
 - Procurement 
 - Human resources	
 - Communications	 
 - Risk management 
 - Stakeholder management

Where some of them, as previously stated, are 'basics' for a Project Leader / Manager, and others will... well... fall into a 'gray' area that varies from company to company and maybe from market to market.

I've checked some similar questions like ['The difference between a Functional and a Project Manager'][4] and ['The difference between a Project Manager and a Project Leader'][5] and turns out that the former is focused on two specific and not overlapping roles (from my point of view) whereas the latter is understanding both Leader and Manager from a 'controlling' perspective (by force or by willing) which is not what I'm referring to in my question.

*Bottomline:* Is it correct to call one *Project Manager* even if this 'Leader', 'Manager', or any other expression we want to use, does not deal with project *costs*?
