Here's how to write an executive summary (with examples) so you never have to read the entire report just to get a few details. It's a short, informative version of the long document - business plan or proposal - that includes all the critical information anyone needs in one go. But there's another document that's equally important - and that is an executive summary. I've learned a lot since then - and, most importantly, the need to put a lot of thought into it and make ideas work.Ī business plan or project proposal may not seem like the most important or complicated document, but it can guide the entire company and can even be shared with investors to win prospects. I wrote my first business plan when I started my company (so I know the firsthand challenges). Keeping up with long documents like business plans or project proposals can be a tricky task.
