In hindsight, a certain percentage of expenditure is always wasted. Waste is usually the result of risks that go bad or lack of experience in a key field.
Examples of waste:
Relate waste to the stage of your organization. Identifiable waste is at a minimum in a small, new organization. In hindsight, it will one day seem that waste is quite high because it has put resources into projects that didn't work.
Large, well-resourced organizations appear wasteful and often are. But sometimes they're not. Perhaps they're too big to simply absorb costs that a small organization would. For example, they need to buy all their own proper equipment and hire professionals. Perhaps they simply have the resources to do a good job without pinching pennies. (E.g. hire the best people.) Sometimes they invest in better resources because it is actually more profitable than minimum performance resources. That is, they achieve economies of scale.
