Blog 24. Capture new requirements for the electronic expansion

In the last blog, 7, I performed the trick to decompose the restrictions on the caravan and the caravan environment (presented in blog 4) into requirements concerning only the electronic expansion black box (presented in blog 6). I stated how each environment restriction would affect the electronic expansion black box.

After the decomposition of existing requirements, it is now time to fill up with new requirements on the electronic expansion black box, not having any consequence from outside the black box, but not yet being considered.

After decomposing requirements number 1 to 5, I will now capture the new requirements as parts of requirement number 6. These can be anything considered a user of the electronic expansion (via interface -E-2). As you can see when reading these requirements, the user is a hard rocker who wants to play loud music the night around, using electricity charged by the solar panel, when he sleeps in the daytime. Also, he wants to be internet-connected, to stream music from Spotify.

Now the electronic expansion is relatively well understood and described; in the next blog, I will show how to find solutions to these requirements.
