Productyping is the evil twin of pretotyping. If pretotyping can be summarized as: “make sure you are building the right it before you build it right,” productyping can be summarized as: “build it right even if you are not sure you are building the right it.”Here are some signs that you might be productyping instead of pretotyping:
- You add non-critical features and embellishments that no user has requested.
- You worry about scalability when you don't even have 100 (or 10) users.
- You spend too much time to tweaking the UI: This line should be 3 pixels instead of 2.
- ...
And here's the grandaddy of them all:
- You prematurely design and develop a general solution instead of addressing specific needs, problems and requests of your existing users in a timely manner.
This XKCD comic really hits the spot on this last point:
