SCOPING DIAGRAM
Objective:
-
To organize all possible elements that is related to a problem for scoping it.
Method:
-
Thoroughly investigates all elements related to the problem at hand.
-
Fill in the scoping diagram and identify the foci.
-
Use this diagram to produce a set of engineering requirements corresponding to you foci.
Key tips:
-
Make sure to do some research and interviews before using this tool, because it is limited when you ties to scope your problem without having enough background knowledge for the problem.
Flexibilities:
-
This tool is also useful when you want to perform a quick interview because you can first ask the questions that related to your foci. If time allows, you can then ask other questions
PAIRWISE COMPARISON
Objective:
-
To rank the relative importance/preference of objectives/design concepts/alternatives.
Method:
-
Create a square matrix with objectives on the first row and first column.
-
Cross out diagonal entries in the matrix.
-
If one objective is more preferred than the other, score 1; otherwise, score 0.
-
Tabulate all the score horizontally and rank them in descending order - most critical to least.
Flexibilities:
-
As seen in this example picture, instead of 1 and 0, a scale from 1-3 of how critical it is used. The scoring scale is up to you to decide.

This activity does not require that each team member be highly knowledgeable about each asset. As long as there is at least one person who can explain satisfactorily to the rest of the group why the loss of one of two assets would have the greater or equal negative impact on the business, the group can reach a consensus about the asset pair.
