Values - LuxuryPhoneConfig - IBD

In this IBD, the initialValues compartments reveal that in the context of the block LuxurySmartPhone the sensors for the front and back cameras have the Context-Specific Values 14.0 MP and 24.0 MP respectively for pixels:

The upper IBD shows how one might present the result to stakeholders; the notation can be easily read by non-SysMLers (except for the unfortunate naming of the initialValues compartment).

For the brave, the lower IBD shows an advanced "under-the-hood" view with the initialValues also for the parts at each level, so that we can see that, in fact, from the point of view of each Block, parts too may have Context-Specific Values (which is very useful for some systems configuration problems).

Please note again that in the tool:

MagicDraw/Cameo: For context-specific values you do not have to deal with fiddly instances, you can edit the values directly in the 'initialValues' compartment! Enable 'Tools > Define Context Specific Initial Value' on a part whose Block has a value.

MagicDraw/Cameo: The context menu item 'Tools > Define Context-Specific Value' will only be available UNTIL you have assigned one! Thereafter it does not appear anymore because the tool will have already created a tree of instances to carry the values.

MagicDraw/Cameo: The context menu item 'Tools > Define Context-Specific Value' will only ever be available in an Internal Block Diagram on a part property symbol typed by a Block that has a value property!

Finally, let's look next at how the entire 3 layers of "deep" re-configuration fit together.

Notes

[ASSERTION, NAMING, WARNING] The SysML block compartment name 'initialValues' for what are really "context-specific values" is confusing - even completely misleading; please just think of them as 'contextValues' (and initial values as a special context case)

[DISPLAY, FEATURE, TIP, TOOL] MagicDraw/Cameo: To show the type of initialValues (context-specific values) use the display option Show Slot Type

[CAPABILITY, FEATURE, TIP, TOOL] MagicDraw/Cameo: You can edit context-specific values (initial values) directly in an IBD by using the context menu item Tools > Define Context Specific Initial Values on appropriate blocks; once activated you can edit the values directly like Slot values

[FEATURE, TIP, TOOL]{INFORMATIVE} MagicDraw/Cameo: For context-specific values you do not have to deal with fiddly instances, you can edit the values directly in the 'initialValues' compartment! Enable 'Tools > Define Context Specific Initial Value' on a part whose Block has a value.
