Common / Authoritative DefinitionsThe following are common or authoritative definitions that are arguably somewhat flawed.
A set of tasks that must be completed in order to arrive at a particular goal or outcome. [often quoted definition with many minor variations and an unclear source]
Projects have objectives but not necessarily goals or outcomes. For example, a project to build a set for a film where the set itself isn't a desired goal or outcome but is rather an objective that brings you closer to goals such as film revenue.The phrasing "must be completed" is inaccurate because there may be many ways to achieve an objective.
A temporary endeavor undertaken to create a unique product, service or result. (PMI, 2008a, p. 5)
Why does the result need to be unique? All things are endeavors are arguably temporary but why is this a defining characteristic of a project? The intent here appears to differentiate between a project and process where a process is repeated exactly the same way many times.Why list products and services? Projects can create infrastructure, knowledge, analysis, events and so forth."create" is inaccurate as most projects update existing things.
A project is any undertaking, carried out individually or collaboratively and possibly involving research or design, that is carefully planned to achieve a particular aim. [Wikipedia project page 2022]
"... possibly involving research or design ..." --- and possibly involving driving to Denver or possibly involving a ham sandwich."... a particular aim." -- projects may have dozens of objectives.
