Feature Solution Problem

Consider a feature that can be done in a few different ways. Solution 1 is estimated to take 8-weeks and is the gold plated version. Solution 2 is also estimated at 8-weeks and is the silver version. Solution 3 is estimated at 6-weeks and is the bronze version. Which option do you chose? Certainly not the silver since it takes the same time to produce gold right?


We don't have all the information to make an informed decision. We don't know what the initial costs are for each solution. We don't know the TCO (Total Cost of Ownership) for the long term. We don't know the risks.


Lets put up some more info:


Sol 1: Needs 6 human resources for a cost factor of 8.6. Requires licensing at a yoy cost factor of .2. Requires 2 new long-term commodities at a cost-factor of 3.3. Has a potential impact of other projects due to resource constraints.


Sol 2: Needs 4 human resources at a cost factor of 9. No licensing required. Requires 1 new commodity at a cost of 2.3. Has a potential impact on other projects.


Sol 3: Needs 4 human resources at a cost factor of 6. No licensing. No new commodities. No risk to other projects. Long term risks due to support, estimated at yoy cost of 1.1.


Which is the best option? Still, we haven't normalized the information. We don't know the long-term costs of 1 & 2. We don't know details of coat to other projects...something more to think about.
