When a contractor is remodeling your bathroom or your garden, the amount of time spent planning the design is insignificant compared to the cost of labor and supplies. But in software, the planning is the entire project. The closer the plan is to covering every single possible case, the closer the software is to being done. In construction, the work doesn't even start until the plan is done. Every one of these comparisons that involve a physical product whether it's contracting, bridge building, or manufacturing all completely miss the mark. If you compare with other industries where the plan is the product, you'll start to see more similarities with software development. And the less the planning is cookie-cutter the more trouble those industries have with estimates as well.
