What are the methods for evaluating the effectiveness of IT projects?

Question

Project management

Excluding purely financial valuation methods

Answer 1

Of course, there is not enough information to answer the question)
Read the book by Tom DeMarco "Deadline. A novel about project management", the book is not large and easy to read. But there you can find answers to many questions.

Answer 2

You have not defined performance criteria. First determine it, then you yourself will find the answer to your question.

Answer 3

I agree with begemot_sun.
If one of the goals of the project was to educate newcomers, these are the same criteria and methods of evaluation.
If the goal was to use the project as a channel for PR - for example, the number of clients who came from it will be an assessment method.
Although you asked for non-financial methods and criteria for the success of the project, I think that all other criteria ultimately come down to money, to the marginality of the project.
Look:
the release was on time, which means there were no costs for the maintenance of the team, rent, etc. during project downtime.
The task set for the project has been solved, which means that there will be no improvements to the project, an increase in the project time, or the cost of paying for this time. Or maybe you will have time to finish the new functionality for an additional cost or take a new project to work.
The emotional resource of the team is saved - it means that the first two points are more likely to be completed than if the team is exhausted.
