Ranking of Likely Conflicting Values
Extracting/synthesizing values from the Holistic List of values and considering other possible values, the project has attempted to specify key values in relative order of desirability. This Ranking of Likely Conflicting Values will help when trade-offs and judgments have to be made.

Explanation |
| 1 |
Cost of Production |
- Production = Operations, data entry, support after implementation, …
- Low Cost of Production implies that reducing the ongoing cost is the driving concern and that other variables might be adjusted to reduce this cost.
- If there is a high value on lowering the cost of production, typically the cost of development will rise.
|
| 2 |
Time/Speed |
- Meets product delivery deadline.
- The rate at which the solution is delivered without regard to the quality of the solution.
- High speed implies that other variables will be sacrificed in order to achieve quick deliverables.
|
| 3 |
Quality |
- Consistency without error.
- The raw goodness of the final results in terms of usability, reliability, fitness for a purpose, etc. How suitable is the end result for a purpose.
- High quality implies that there will be added quality assurance activities, and that fitness for an intended purpose will not be abridged to make deadlines and cost targets.
|
| 4 |
Functionality |
- Solution performs according to full range of specifications.
- High functionality means that the breadth of coverage of the solution (in terms of goals, functionality, or features) will not be compromised to make deadlines or cost targets.
- Note: We assumed that if we compromised functionality we would still provide a meaningful solution.
- Given that we will seek an incremental development strategy, parts of the functionality would be delivered at different times. This timing does NOT imply compromising or cutting the functionality.
|
| 5 |
Reusability |
- The extent to which the effort will utilize AND create reusable components (analysis, design or actual product components).
- High reusability implies that there are formal activities to locate and attempt to use existing reusable components and that there are formal activities to identify, develop and certify new reusable components.
|
| 6 |
Cost of Development |
- This is an inverse relationship with the cost of production. Low cost of development implies that reducing cost and producing the results at a low cost is the driving concern and that the other variables might be adjusted to reduce the cost.
- For example, it is cheaper to "hard code". However, the resulting cost to make changes or support flexibility will raise the Cost of Production.
|
| 7 |
Fit for the Registries |
- The degree to which the solution meets the Registries' needs. For example:
- The solution has a "core", but with flexibility for extensions to meet Registry specific needs. Thus, all Registries could be served fully.
- The solution is a traditional application that meets 80% of their needs without any real means to extend the solution per Registry.
