At the risk of sounding like a broken record: Paper protoyping. Even if it's for yourself, it never feels the same to interact with a product than you think it will. This holds even more true when it's for other people.
For internal projects, investment is obviously a huge problem, and once you've built the wrong thing you're unlikely to get more money to do it right. But for a given price point, there's a huge range of quality you can obtain. Paper protoyping helps you maximize that at very low expense.
