I am working on a Modernization of Operations in a Data intensive company where operation major work is data validation, File checks and application monitoring.. Can you suggest what should be my pat

You ask “what should be my part” with a specific objective “to provide a one-click operation”. I guess it depends a bit on your role. It seems there is some hybrid/mixed role that you’re in or different type of responsibilities are assigned.

If you’re a PM with no programming skills: If I were in this situation, I would put myself in the position of an implementor/manager accountable for delivering a working solution according to the collected requirements.

If you’re a programmer in a PM shoes: I would rather put on a “developer hat” and focus on coding and testing the program. Pushing any BA/PM tasks out of my scope. Alternatively asking for a clear segregation of duties.
