An interesting way to visualize this concept, from @andrewchen's presentation is as follows:
I also took some notes from the discussion:
- Twitter, Facebook, Google all started as MDPs (without a viable business model)
- Viability is measurable, whereas desirability is more difficult to measure
- Desirability is about demand -- does it exist at any price (including free)
- Are you viable initially, or only after X number of users?
- MDPs can give awareness, publicity, etc. to a company to help them launch 2nd, 3rd products
- MySpace -- Still viable, but not as desirable anymore?
- Just starting out: Tradeoffs between desirability and viability
- Desirability is a _component_ of viability
- MVP when spoken about, often really refers to MDP
- Can viability kill desirability? (ie. Facebook early stages)
- With a desirable product, your viability may be tied to different users than you think
- Like "Ladies Night" -- free customers and paying customers
- What should you focus on at what time? Feasibility vs. Desirability vs. Viability
- Feasibility is a lot easier for most type of applications now
- Viability is easier too since costs have gone down
- So the most difficult part now might be Desirability
