What are the three primary variables (or triple constraints) in any project?

"Time, cost and scope" are the three variables which is the correct answer for the above question.

Explanation:

Time: Time is the first primary variable of any project which is necessary because if time will change the technology will also be changed. For example, If there is an IoT project which takes around one year in development. But after one month of starting a project of one organization the other organization deploy the project into the market and then the project has no use (which is in development phase) when it deploys after 11 months. Cost: The second primary variable is cost because If there is more cost for one project then it will develop first than the other which cost is less. It is because everyone has the importance of money. Scope: The third primary variable is a scope which defined the cost and value of the project in the market. If the scope of any project is limited then there is the limited value of that project in the market. The above question asked about the three primary variables for any project which are Time, Cost and Scope which is described above.
