Biggest challenge? Clarity. A lot of projects start with a vague goal — like “make it better” or “get everything.” Sounds fine, but unless everyone agrees on what success looks like, you end up spinning your wheels or fixing the wrong thing.

Let me know if you want to dig deeper.

one of my biggest challenge when starting project, it's when the goals are not Clear and the find a Realistic Scope. i remember i was working on a project and i suppose to deliver some structural advise and structural design but the client wasn't clear about what he really need to build, therefore starting this project was a challenge and also respecting the delail was a challenge as the deliverable was not clear

Unclear objective and lack of proper planning at the initial stages of the project are my biggest challenge when starting a project.
