What is the classifying noun for a person who is both a project team member and a consumer of the final product?

Question

In an example scenario, two people, say a capenter and a plumber, are both working on a shopping mall construction project. The carpenter, lives in a foreign land, will return home when her direct involvement in the project is complete, while the plumber is a local lad and is looking forward to taking advantage of the wonderful purchasing opportunities the new mall will offer.

Both the carpenter and the plumber are project team members.

What single term describes the plumber's involvement with the project as both a project team member and a consumer?

Answer 1

(dual) stakeholder

From dictionary.cambridge.org:

stakeholder noun

a person such as an employee, customer, or citizen who is involved with an organization, society, etc. and therefore has responsibilities towards it and an interest in its success

The interesting part is that in your example, both the carpenter and the plumber are stakeholders (as employees, explicitly having responsibilities towards it). Also, implicit is their interest in its success, to see their effort bear fruit.

However, the plumber additionally is a stakeholder with an explicit interest in its success as someone who is (looking forward to be) a customer. Also, as a local citizen, he perhaps has an implict interest in its success due to the associated developments it may bring.

Probably, you can call the plumber a dual stakeholder.

Note: Silenus did use the term stakes in an earlier comment.
