Project Manager VS Program Manager
While there are similarities between managers of projects and programs, there are also stark differences between both roles. It helps if you look at the differences between projects and programs which require similar management styles, but have different overall objectives. Thus, the project manager vs program manager dynamic is in place.
A project is a singular effect that is focused on a concept or product while a program consists of several projects that fall under the same department. This means that running a program is far more complicated than overseeing a single project which means that different skill sets and objectives apply when it comes to managing the overall effort.
To put it another way, a project is a temporary effort that has a singular goal while a program is several projects grouped together because of their general similarities. For example, a marketing campaign may be considered a program that promotes several different projects that include traditional media, promotions, social media, public relations, and more.
