ScopeSnap FAQ

What kind of input does ScopeSnap need to work?

ScopeSnap is designed to work with the raw, unstructured text you already have from discovery.

ScopeSnap ensures you are estimating a complete and well-defined scope, which dramatically improves overall estimate accuracy.

Can I customize the generated proposals?

Yes. The proposals and Statements of Work generated by ScopeSnap are built from your refined scope and estimates.

Is ScopeSnap suitable for very large, complex enterprise projects?

Absolutely. ScopeSnap is built to handle complexity. Its methodology of breaking down large ideas into epics and detailed tasks is ideal for enterprise projects.
