Do you have to build a full operating model when performing a DCF analysis?

Doing one for a stock pitch for an investment club. Is there any quicker way to do it? Intuitively with the accounts needed for a DCF I could always take the shortcut and project capex as a % of sales and depreciation as a % of capex, but do industry professionals build a full 3 statement model with depreciation/debt/NWC schedule every time they do a DCF analysis(or more specifically, calculating unlevered free cash flow as capex/dep/change in NWC is projected).

No, they don't. It really depends on the situation and timeline. It can also depend on your group

If you're doing a quick and dirty DCF valuation analysis (e.g. as part of a pitchbook) using only public information (e.g. company filings, equity research), then often times a full 3-statement operating model is not needed. You can project out the main line items/schedules, use company guidance, use equity research estimates, make general assumptions/flatline (% of sales) etc. When your information is limited, building an overly detailed/complex model can be redundant. Too many assumptions can lead to false precision (garbage in, garbage out.)

If you're working on a more important project or a live deal, then you'll have better, more detailed financial forecasts (e.g. management model, seller model, input from tax advisors etc). In this case, building a 3-statement model is the norm.

That being said, since your project is for school and you likely have the time, I would just build the 3-statement model for practice.
