I haven't written a prototype in forever. I don't find them effective. And they typically take way longer than you expect at the outset.

Do some wire charts or graphics and present those. It's far more boring to do than writing a prototype, and learning design tools is cumbersome, but they allow you to demo things better to executives, redraw stuff on the fly in meetings, copy and paste to a document or slideshow, share with external parties, and people don't get hung up on minutae that come with presenting a prototype. Stakeholders far prefer seeing a well thought out document or slideshow than a dinky fake app.

Once you get signoff on the design and flow, then jump straight into the real code, skip the whole prototype step.

I'd rather be coding, but sometimes it's just not the most efficient use of my time.
