1) it failed to communicate and market it’s product
2) it’s product didn’t fit the user’s needs
3) it’s technology strategy made development too expensive
4) it’s product technical quality was too low
5) it’s product did not look appealing to potential new users
Developers are responsible for 3 and 4, sales and marketing for 1 and finally designers for 2 and 5.
With competent developers you can start a startup and make sure 3 and 4 never come to pass, but lack of good product designer will eventually kill it.
Here I use the broader sense of user-centered designer, which includes:
- research
- testing
- prototyping
- validation
- UI/UX design
- visual design
- …
The first four being the most important for a product market fit.
This is especially important for B2B products, because there understanding the needs of the business and their processes is key to making sure the product fits the user’s day-to-day work but the businesses’ future needs as well.
It may not be common, but you can and should use extended UCD research methods on the customer business processes itself instead of relying on PMs and sales just asking customer’s what they want. (This is often called Business Design or Service Design around here.)
