OSE Specification Score

O-5 Score:

0- nil 1- hardly any 2- some 3- considerable 4- good 5- excellent

1. scalability - can same design be simply used? Full Extensive Scalability and Intensive Scalability are 5. Order of magnitude for Full is 2 - from one person or a few to 100 or a few hundred - based on Dunbar's number as minimum village design. 0 is no Scalability, 1 is under 2. 2 is double size. 3 is no extensive Scalability, but intensive Scalability works well. 4 is full extensive Scalability. 5 is full extensive and Intensive Scalability.
2. modularity. O is dedicated parts, used nowhere else in Set. 1 is a single common module. 2 is 10% of modulesused in other machines, and 3/is same as 2 but many (5+) other machines use the modules. 4 - most of device is common modules. 5- all of the modules are used in other machines.
3. Unique parts count. 0 is >100 unique parts or modules
4. robustness
5. product Ecology
6. sourcing - reliability of sourcing. 0 is when there is a monopsony.
7. Fabrication Paralleling. If unique parts are low, and majority of the same operations can be done at least by 12 people, then it's 5. If only some of fab can be massively paralleled, the it's 4. If most of fab cannot be highly parallel, but some if it can then it's 3. 2 is when none of the fab can be highly parallel, such as only 4 people can engage. 1 is when entire process is linear, but at least a few people can be allocated to linear tasks. 0 is when the entire process is linear, and only up to a pair can work on each task. Best case is when there is a low number of steps, and each step is done by an unlimited number of people, limits donly by body count and tool count. This means that it's a fully modular design.
